`02 Daploy HMS Polypropylene for Foam Extrusion
`
`Polypropylene foam
`
`Polymeric foams consume around 3.5 million tonnes of plastics materials
`
`annually and account for about 10 % of all polymer usage in Europe. Foamed
`
`polymers are used in a wide number of application areas, which range from
`
`construction, automotive and household products to food and protective
`
`packaging. Among the many benefits of foamed materials are their good
`
`mechanical rigidity at low specific gravity, thermal and acoustic insulation,
`
`cushioning against mechanical shock and a significant contribution to source
`
`reduction in raw material usage.
`
`The foam market is dominated by the amorphous polymers (such as PS, PU
`
`and PVC) which have been industrially foamed for more than 50 years.
`
`Polypropylene (PP) foams are a relative late comer to this market. The reasons
`
`for this lie in the molecular structure — standard PP's are semi-crystalline
`
`materials with a linear molecular structure. They lack the required extensional
`
`rheological properties in the melt phase which are required for the production
`
`of extruded low density foams with a fine and controlled cell structure. This
`
`limitation is resolved by the Borealis Daploy range of High Melt Strength (HMS)
`
`PP products. These are long chain branched materials, which combine both high
`
`melt strength and extensibility in the melt phase. They open up the possibility
`
`of bringing the many well-known property benefits of PP into the world of low
`
`density polymeric foams. These benefits include a wide mechanical property
`
`range, high heat stability, good chemical resistance and no monomer issues. PP
`
`also brings its good environmental credentials to this market.
`
`From a fairly recent and small beginning, the global PP foam market is growing
`
`rapidly (>20 %/year). Current PP foam applications include automotive,
`
`insulation, food and protective packaging. In Europe, the dominant PP foam
`
`applications are in the food packaging and automotive areas.

`
`In the case of food packaging, PP foam offers a lightweight packaging
`
`solution with excellent grease/fat resistance (no stress cracking) and with
`
`no issues surrounding its monomer. Its high heat stability means products
`
`are microwaveable, with good thermal insulation giving them a ‘cool touch’
`
`during removal.

`applications
`
`In automotive applications, lightweight foam solutions are helping to improve
`
`vehicle performance and fuel efficiency. With increasing pressure for
`
`end-of-life vehicle recycling, mono-material solutions are being sought and,
`
`with PP becoming a preferred polymer, recyclable foamed PP solutions are a
`
`logical next step. PP foams have an excellent moisture barrier and chemical
`
`resistance which are important for durability and functionality in the presence
`
`of hot oil, grease or fuel. Its high heat stability also opens up the possibility
`
`for under the bonnet applications. PP foams also have very good cushioning
`
`properties, thereby contributing to improved driver and passenger safety.
`
`As a leading PP supplier, Borealis is committed to supporting the
`
`development of the extruded PP foam market through its Daploy HMS PP
`
`products and by offering PP foam solutions.

`
`Daploy HMS-PP
`
`The basic extensional rheological properties of the long branched Daploy
`
`HMS-PP products are shown in figure 3, in comparison to those of standard
`
`linear PP's. The window in the high melt strength and extensibility area of this
`
`graph defines the requirements for a high performance foaming grade. With
`
`such long chain branched polymers, it is possible to produce very low density
`
`(20 - 50 kg/m‘*) extruded PP foams which possess a fine and controlled closed
`
`cell structure. This is not possible with standard linear PP's or modified
`
`materials which fall outside the critical high performance foaming window.

`
`Daploy HMS-PP products can be blended with the full range of standard PP
`
`extrusion grades and other polyolefinic products. This offers the opportunity
`
`to widely tailor the foam properties to meet the particular demands of the
`
`end-use application. Furthermore, Daploy HMS-PP products are specifically
`
`designed to be suitable for processing on most types of existing industrial
`
`foaming equipment.
`
`Daploy HMS-PP products and their blends are not crosslinked. This means
`
`that extruded PP foams produced from them are fully recyclable, an
`
`increasingly important environmental demand within the polymer industry.

`
`Foam extrusion process
`
`The first steps in the foaming process (polymer feeding and melting) are
`
`common to all extrusion processes. However, three later stages are specific
`
`and critical to the process, as illustrated in figure 4.
`
`These three specific steps in the foam extrusion process comprise of
`
`(a) dissolving of a blowing agent gas in the polymer melt
`
`(b) cell nucleation
`
`(c) cell growth and stabilization
`
`In order to perform these additional steps, foaming extruders are longer
`
`than standard types, typically with an overall L/D ratio > 40, in either a single
`
`or tandem extruder configuration.

`
`Polymer-gas solution
`
`A blowing agent is introduced into the polymer melt either by direct gas
`
`injection (physical foaming) or by decomposition of an added chemical
`
`blowing agent (chemical foaming). In both cases, a key requirement for a
`
`uniform and controlled cell structure is a homogenous polymer-gas solution.
`
`This is controlled by two factors: the solubility of the blowing agent gas in the
`
`polymer and the sorption kinetics. The solubility itself is not the limiting factor
`
`Fig ure 5: Solubility of common blowing agent
`gases In PP
`
`for foaming when using the more common industrial
`
`foaming agents: butane and carbon dioxide. With the gas
`
`concentrations typically used in foam extrusion, these
`
`can be quantitatively dissolved with standard extrusion
`
`pressures up to 10 MPa (100 bar). Figure 5 shows the
`
`equilibrium solubility curves for the more common
`
`blowing agent gases in PP.
`
`The achievement of equilibrium solubility is determined by
`
`the sorption kinetics and this is therefore a time dependent
`
`process. This process can be accelerated by raising the
`
`melt temperature and using screw designs which promote
`
`good mixing of the polymer melt and injected gas.

`
`Cell nucleation
`
`Control of cell nucleation is crucial to obtaining the desired fine and uniform
`
`cell structure of the final foam. It is a complex area with several, often
`
`interrelated, factors playing a ro|e.The three main factors which influence
`
`the cell nucleation are the pressure drop in the die, the concentration of the
`
`blowing agent and the concentration of the external cell nucleating agent.
`
`The rate of pressure drop at the die is determined by the die geometry.
`
`Higher rates of pressure drop at the die significantly increase the cell density,
`
`irrespective of the concentration of blowing agent gas or external nucleator.
`
`High shear rates are also believed to play a role in promoting cell nucleation.
`
`It has also been established that higher concentrations of blowing agent gas
`
`lead to increased cell density. The addition of external nucleating agents is
`
`the most commonly used method of controlling cell nucleation in the foaming
`
`process. These are basically finely divided and dispersed solid particles (eg.
`
`talc), which provide sites for cell nucleation. Figure 6 shows an example of the
`
`influence of these two factors on cell density in the case of PP foamed with
`butane and talc as the nucleator.

`

`
`Cell growth and stabilization
`
`Melt temperature is one of the most important process parameters in foam
`
`extrusion. In the case of PP foam, depending on the type and concentration
`
`of the foaming agent used, the optimum in melt temperature may vary from
`
`approximately 130°C to 180°C.
`
`When the melt temperature is too low, foaming is limited because the
`
`material solidifies before the cells have the possibility to expand fully. When
`
`the temperature is too high, the foam first expands, then collapses again due
`
`to lack of stabilization of the structure. There is an optimum melt temperature
`
`window for foaming in which lowest densities are achieved; this temperature
`
`is lower than the standard PP melt temperatures (210°C to 240°C). The latter
`
`part of the foam extruder is dedicated to the melt cooling and intimate mixing
`
`of the polymer-gas system.
`
`It is during this part of the process that the Daploy HMS-PP plays its crucial
`
`role. Its high melt strength and extensibility help to control cell growth. By
`
`a ‘strain hardening’ mechanism it prevents rupture of the cell walls and
`
`coalescence, which would otherwise lead to a polymer containing a few
`
`rather large holes in it — far from the desired fine and closed cell structure.
`
`The foam is finally stabilised by a cooling stage before winding. This is
`
`either by means of a calibrating mandrel in the case of an annular die or by
`a conventional roll stack when a flat die is used.

`08 Daploy HMS Polypropylene for Foam Extrusion
`
`Daploy HMS-PP blends and foamability
`
`In order to modify the final foam properties, Daploy HMS-PP's can be blended
`
`with standard extrusion grade PP’s, as will be described in more detail in the
`next section.
`
`An important consideration, however, is the foamability of such blends. When
`
`a long chain branched PP is mixed with a standard PP, it is evident that this
`
`will have a ‘diluting’ effect on the melt strength and extensibility of the blend
`
`compared with that of the pure HMS-PP. This effect is shown in figure 7.
`
`It can be seen, however, that quite high levels (approx. 60 %) of blend partner
`
`can be added before the extensional rheological properties of the blend begin
`
`to fall outside the critical high performance foaming window.
`
`This is further verified in figure 8, where the minimum achievable foam
`
`density is shown as a function of the HMS-PP content in the blend. A wide
`
`range of blend compositions where it is possible to produce low density
`
`(<100 kg/m3) PP foams exist.

`
`Providing PP foam solutions
`
`The modification of foam properties is a crucial requirement in order to be able
`
`to produce PP foams with properties that meet the technical performance
`
`demands of particular end-use applications.
`
`The homopolymer based HMS-PP’s can be used pure or blended with
`
`standard homopolymers, providing foams with high stiffness and heat
`
`stability. Enhancements in impact strength and toughness of the foam
`
`can be achieved by using random or heterophasic (block) copolymers as
`
`blend partners. In the case of random copolymers, impact performance
`
`is improved at temperatures above approximately 0°C. If good impact
`
`performance is required at low temperatures (< 0°C) then heterophasic
`
`copolymers should be used.
`
`Further interesting property modifications can be made available by using
`
`Borealis Borsoftm random heterophasic copolymers as blend partners. These
`
`are soft PP’s (tensile modulus ~400 MPa). The blend with these products
`
`provides the opportunity to produce soft PP foams with good impact strength
`
`and toughness at low temperatures. Even softer foams can be obtained
`
`by blending Daploy HMS-PP’s with various polymeric materials such as
`
`metallocene LLDPE's, TPO's and EVA's.
`
`Borealis has recently developed random copolymer based HMS-PP. Blends
`
`with this product family will result in even softer foam and enable their use in
`
`a wide range of existing and newly developed applications.

`
`10 Daploy HMS Polypropylene for Foam Extrusion
`
`The above general description of HMS blends can be further refined to
`
`provide more quantitative predictions of PP foam properties. This makes use
`
`of various theoretical models for describing foam properties. One of the more
`
`important foam properties is the tensile modulus which is determined by
`
`three basic parameters:
`
`0 Tensile modulus of the compact material
`
`0 Foam density
`
`0 Foam structure
`
`The tensile modulus of the starting (compact) material is determined by the
`
`chosen blend partner and the composition — typically this modulus will be in
`
`the range of 750 to 2,000 MPa. The tensile modulus of the foamed material
`
`will decrease as the density decreases. The third parameter is foam structure
`
`and this relates to factors such as the relative proportions of open and closed
`cells and cell size.
`
`Figure 10 shows experimental data for tensile modulus as a function of
`
`foam density for different Borealis blend partners. The agreement with the
`
`theoretical predictions is good and this provides confidence in the ability to
`
`use this as a quantitative tool.

`
`Similar predictions can be made for other foam properties, for instance,
`
`in the of case thermal insulation. Figure 11 shows the variation of thermal
`
`conductivity with foam density. It can be seen that at low densities (ca. 1 00
`
`kg/m3) the thermal conductivity is reduced by a factor of about ten, when
`
`compared to compact PP.
