Seblex 7839/4 HS UV2 is a calcium carbonate filled thermoplastic styrenic rubber modified polypropylene compound which has been oil extended. It is a high flow injection moulding grade. It is also quite shear thinning and has good mould filling capability. It has been developed for flexibility and low surface hardness to give it "soft-feel" characteristics and stabilized for automotive heat ageing and weathering requirements.
