氟塑料 FEP F46系列
FEP fluoroplastic products ( F46 )

● 主要性能 Key Features
    聚全氟乙丙烯(Fs46、FEP)是一种新型的结晶型全氟碳高聚物,是聚四氟乙烯的改性产品,它的长期使用温度为-80~200℃,并具有优异的化学稳定性、突出的表面不粘性、低温机械强度、电绝缘性、气密性、耐褶性,以及很低的吸水性和摩擦系数,在大气中暴露寿命可超过40年。
    Perfluorinated ethylene-propylene copolymer ( F46,FEP ) is a new kind of crystalline perfluorocarbon polymer. It is a modified product of PTFE, and its long-term working temperature is from -80~200℃. It has excellent chemical stability, outstanding surface lubricity, high mechanical strength at low temperature, electrical insulation, air tightness, non-creasing property, low water absorption and friction coefficient, as well as an exposure life more than 40 years in the atmosphere.

● 主要用途 Main application
    用于电缆外绝缘层,尤其作复杂电子设备内的导线绝缘层有更好的使用效果,FEP制作的各类热收缩管和薄膜可紧套在需防粘、防腐的辊筒或其它设备上,已在化工、印染、食品等行业深受欢迎,FEP制作的“U”型防粘夹条用于纺织工业设备的浆纱机上,防止化学浆粘住机械部件,也可用于冶炼行业电解铜工业中种板的保护边。FEP制作的管材还大量用腐蚀性液体和气体的输送管、内衬管、热交换器管、液面针。
It is used as outer insulating layer in cables, and especially has better effect as insulation on the complex electronics equipments. FEP heat shrinkable tubes and film can be tightly tubed around antiseize or anticorrosive rollers and other equipments, which are widely used in chemical, printing, dyeing, and food industry, etc. FEP U-form antiaeize clip bars are used in sizing machines in textile industry to prevent chemical pulp from sticking mechanical components, also can be used as groove guards for starting sheets in copper electro-refining industry. FEP pipes products are also widely used as the pipelines for corrosive liquid and gas, liner pipes, heat exchanger tubes, and liquid level indicators.
