Abstract: The invention pertains to a fluoropolymer composition including at least a vinylidene fluoride (VDF) homopolymer, a VDF semi-crystalline copolymer, and a polyethylene additive, which is suitable for the manufacture of parts of mobile electronic devices, to a method for the manufacture of said parts, and to a method of manufacturing a mobile electronic device using said parts.

Abstract: Described herein are polyamide polymer compositions including a polyamide polymer, a long reinforcing fiber, and a heat stabilizer. Optionally, the polyamide polymer composition can further include an additive. The polyamide polymer compositions are selectively engineered to leverage improved heat stabilization and improved mechanical performances to synergistically improve the high temperature performance of the polyamide polymer composition. The polyamide polymer compositions can be advantageously incorporated into articles used in high temperature applications settings, at least in part due to the synergistically improved high temperature performance.
