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 ...
