Embodiment 1 to 5 and comparative Embodiment 1 to 3

[0052] The compositions of Examples 1 to 5 and Comparative Examples 1 to 3 were prepared by melt blending the components shown in Table 1 in a twin-screw extruder. After exiting the extruder, the blended composition was cooled and cut into pellets. The pellets were surface coated with 0.1% by weight calcium montanate.

[0053] Each sample was rated V-0 according to the UL-94 flammability test on 1 / 16" and 1 / 32" thick rod stock.

Abstract

Disclosed are polyamide compositions containing a polyamide component comprising 20 to 100 weight percent of at least one semiaromatic polyamide, non-halogenated flame retardant comprising one or more of a phosphinate, a disphosphinate and polymers thereof, and zinc borate that have reduced corrosion effects on melt processing equipment.

Description

field of invention [0001] The present invention relates to non-halogenated flame retardant thermoplastic semiaromatic polyamide compositions that reduce the effects of corrosion on melt processing equipment. Background of the invention [0002] Polyamide resins have excellent mechanical properties, moldability, and chemical resistance, and thus have been used in automotive parts, electrical / electronic components, mechanical assemblies, and many other applications. Articles made from polyamide resins can have extremely desirable physical properties. However, in certain applications, it is desirable that the polyamide resin composition be flame retardant and comply with the UL-94 standard for high flame retardancy. This requirement has prompted the development of various methods for imparting flame retardancy to polyamide resins. A common method of imparting flame retardancy to thermoplastic resin compositions involves the incorporation of halogenated organic compounds such ...
