阻燃PEI 1010-7101沙伯基础

阻燃PEI 1010-7101沙伯基础---Pei application fields：Pei has excellentcomprehensive balance performance, which is widely used inelectronic, electrical, aviation and other industries, and as ametal substitute for traditional products and cultural and dailynecessities.

Pei is used in the automotive field, such as manufacturinghigh-temperature connectors, high-power lamps and indicator lights,sensors for controlling the external temperature of automobilecabin (air conditioning temperature sensor) and sensors forcontrolling the temperature of air and fuel mixture (effectivecombustion temperature sensor). It can also be used as a vacuumpump impeller resistant to high temperature lubricating oilerosion, a ground glass joint (socket) of a distiller operating at180 ℃ and a reflector of a non illuminated anti fog lamp.

Pei replaces metal to make optical fiber connector, which canoptimize component structure, simplify manufacturing and assemblysteps, and keep more accurate size.
