NOVELTY - High temperature resistant low shrinkage PA10T composition compirses PA10T, reinforcing filler, glass fiber, antioxidant, lubricant, and other auxiliary agent; the reinforcing filler does not include glass fibers; the average length of the glass fiber is 400-500 μm, the average diameter is 7-15 μm, and coefficient of variation of length is 0.5-0.7. USE - The composition is used for LED reflective support used in LED lamp with incandescent lamp. ADVANTAGE - The composition: can meets the high temperature resistance of PA10T to the greatest extent and improves its dimensional stability during processing and use, and meets the requirements of LED reflector material for high temperature resistance and dimensional stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparing the high temperature resistant low shrinkage PA10T composition comprising adding each raw material into the high-speed mixer, stirring and mixing evenly; feeding the mixed material into the twin-screw extruder from the main feeding port of the twin-screw extruder, melting and mixing, extruding and granulating. LED reflective support, comprising high temperature resistant and low shrinkage PA10T composition.
