Abstract
Polymeric compositions comprising 7-28%, preferably 12 to 25%, of a thermoplastic olefin polymer, 1-10%, preferably 2 to 6%, of a siloxane polymer containing 2-70% of siloxane units and at least 20% by weight of carbonate, urethane or amide units, and 69 to 90%, preferably 72 to 83%, of an elastomer. The olefin polymer can for example be polyethylene, polypropylene, or a polar ethylene copolymer. The elastomer can be 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.
