HEAT RESISTANT THERMOPLASTIC ARTICLES INCLUDING POLYHYDROXY POLYMERS |
摘要 |
<p>Disclosed is a molded or extruded thermoplastic article including a polyamide composition including (a) a polyamide resin having a melting point and/or glass transition; (b) one or more polyhydric alcohols having more than two hydroxyl groups and having a number average molecular weight (Mn) of less than 2000; (c) one or more co-stabilizer(s) (d) one or more reinforcement agents; wherein 4 mm test bars prepared from said polyamide composition, exposed at a test temperature at 170° C. for a test period of 500 hours have a retention of tensile strength, on average, of at least 50 percent, as compared with that of unexposed control of identical composition and shape.</p> |
