Celanese FORTRON® 1140 E7 Polyphenylene Sulfide (PPS)
Categories:	Polymer; Thermoplastic; Polyphenylene Sulfide (PPS); Polyphenylene Sulfide (PPS); Molded
Material Notes:	Description: Fortron 1140E7 is an inherently flame-retardant grade exhibiting extremely low flash and fast cycle times. It has excellent electrical properties, high hardness and stiffness. This grade exhibits good high-temperature load-bearing capabilities. It is especially used for thinner walled and longer flow length parts requiring low flash behavior. Good weldability due to a modest filler level. Commonly used in electrical connectors and other thin wall/long flow length parts. Information provided by Celanese Corporation.
