碳纖維增強聚四氟乙烯
產(chǎn)品牌號:CFRP
產(chǎn)品特性:CFRP制品是由一定長徑(4:1~12:1)的碳纖維與聚四氟乙烯樹脂組成的一種有機復(fù)合材料。
良好的自潤滑性和耐磨性,是理想的無油潤滑密封材料。
廣泛的高低溫使用范圍,可以在-180℃~+280℃范圍內(nèi)長期使用。
優(yōu)異的化學(xué)穩(wěn)定性。強酸、強堿、強氧化劑等腐蝕介質(zhì)對它都不起作用。
耐大氣老化性好。
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.
