Abstract
A thermoplastic polyurethane composition includes a thermoplastic polyurethane (TPU) and a polyoxymethylene. The thermoplastic polyurethane composition comprises 50 to 95 parts by weight of the TPU and 5 to 50 parts by weight of the polyoxymethylene, per 100 parts by weight of the thermoplastic polyurethane composition. The thermoplastic polyurethane composition has an Izod notched impact of greater than 0.5 fflb/in at −40° C. as determined by ASTM D256 10, Method A, and an elastic modulus of greater than 700 psi at 130° C. as determined by ASTM D412. A fluid transfer tube is formed from the thermoplastic polyurethane composition.
Claims20
A thermoplastic polyurethane composition comprising:
- 60 to 95 parts by weight of a thermoplastic polyurethane, per 100 parts by weight of the thermoplastic polyurethane composition;
- 5 to 32 parts by weight of a polyoxymethylene, per 100 parts by weight of the thermoplastic polyurethane composition;
- a compatibilizer comprising maleic anhydride-functional polyethylene or polypropylene;
- and
- a cross-linking agent which is different than said compatibilizer comprising maleic anhydride-functional polyethylene or polypropylene;
- wherein said thermoplastic polyurethane composition has an Izod notched impact of greater than 0.5 ft·lb/in at −40° C. as determined by ASTM D256 10, Method A, and an elastic modulus of greater than 700 psi at 130° C. as determined by ASTM D412.
