ABSTRACT:
Polymeric compositions comprising 5-60%, preferably 12 to 40%, of a thermoplastic olefin polymer, 1-10%, preferably 2 to 6%, of a siloxane polymer and 30-94%, preferably 58 to 86%, of an elastomer. The olefin polymer can be polyethylene or a polar ethylene copolymer. The siloxane polymer can contain polycarbonate blocks. The elastomer can be an amorphous polyamide of low crystallinity, a thermoplastic elastomer, an ionomer, or a styrene/butadiene copolymer. The compositions are particularly useful in the medical field, for example in the form of tubing.
