...shown that more than one third of battery power is used for air-conditioning. Improved temperature management is thus crucial to achieving greater range. Borealis Daploy high melt strength polypropylene (HMS PP) products are used to replace rigid plastic materials in numerous automotive applications, including roof liners, moisture barriers in door modules, and lightweight air ducts. HMS PP products combine both high melt strength and extensibility in the melt phase. They open up the possibilit...

...e high melt viscosity, it is above all the extensibility behaviour of the melt – the strain hardening – that essentially governs the processing properties during coating, foaming and blown film extrusion [8]. Through the use of Daploy HMS (a newly developed HMS-PP), it has now become possible to obtain a combination of melt strength and extensibility comparable with PE-LD. In practical terms, it means that, for the first time, PP can be made to expand much more easily with very low foam densitie...

...it is possible to provide a wide range of properties from rigid and temperature-resistant low-density packaging materials to very soft foams (Fig. 2). The introduction of long-chain branched statistical copolymers with the designation Daploy WB260HMS (Borealis) represents one of the most recent development in this field. While the modulus of elasticity of long-chain branched homopolymers is between 1600 and 2000MPa, and is thus suitable for rigid applications (especially packaging), long-chain ...

Grades with bimodal molecular weight distribution are a possibility, while another is long-chain-branched HMS-PP (grade: Daploy HMS) with high melt strength, which is also significantly extending the range of possible applications for PP in foamed materials, extrusion coating and blow moulding [3]. In this case, advantages are also gained through combination with the nuclea...

...cts made from this foam can be found in automobiles, insulation, food containers and protective packaging. In Europe polypropylene foam applications are mainly found in the food and automobile sectors. The newly developed product Daploy WB 140HMS, which is based on a long chain branched polypropylene with densities down to 35 kg/m3, is particularly suitable for applications in catering and microwave tableware. It is also envisaged that a newly developed high performance polypropylene should be a...

...olymer which permits high-speed production of optically perfect polymer films, and is also sterilizable [3]. When PP is processed as blown film, however, the problem of bubble instability becomes more acute with increase in production speed. Daploy WB180HMS from the family of long-chain branched polypropylenes which only Borealis currently offers can be of service here. Add a few percent to the film formulation (preferably to the middle layer) and production can be boosted by up to 40 %. As Dapl...
