碳纤维增强聚四氟乙烯
产品牌号:CFRP
产品特性:CFRP制品是由一定长径(4:1~12:1)的碳纤维与聚四氟乙烯树脂组成的一种有机复合材料。
良好的自润滑性和耐磨性,是理想的无油润滑密封材料。
广泛的高低温使用范围,可以在-180℃~+280℃范围内长期使用。
优异的化学稳定性。强酸、强碱、强氧化剂等腐蚀介质对它都不起作用。
耐大气老化性好。
Designation: CFRP
Characteristics:
CFRP products are made of a composite material which consists of carbon fibers(aspect ratio 4:1~12:1) and polytetrafluoroethylene resin, characterized by:
Good self-lubrication performance and wear resistance which make them a superior lil-free lubricating sealing material.
Adaptability to awide range of temperatures for lon-term use (from -180℃~+280℃).
Excellent chemical stability to strong acids, alkalies, oxidants and other corrosive mediums.
Good resistance to atomospheric aging.
