Polyacetalharzzusammensetzung und Artikel davon |
摘要 |
A polyacetal resin composition comprising (A) 100 parts by mass of polyacetal resin generating formaldehyde in an amount of not more than 100 ppm when heated at a temperature of 200° C. for 50 minutes under the nitrogen atmosphere and (B) 0.01 to 5 parts by mass of a hydrazide compound can provide an article which is remarkably reduced in an emission amount of formaldehyde even though molded either at a higher temperature or under molding conditions wherein the resin temperature rises partially. Therefore, the polyacetal resin composition can be molded according to various molding methods and under a wide range of molding conditions. The article molded from the resin composition has succeeded in reducing the emission amount of formaldehyde, measured according to VDA275 method, to not more than 1 mg/kg, the level never achieved before, and therefore is usable for various applications where a reduced VOC is required. |
