The phenolic fiber does not melt or burn in a flame at 2500℃. It has good thermal insulation performance and excellent corrosion resistance.
The material is an intermediate phase between PAN fiber and carbon fiber, having high strength and modulus, impregnated with PTFE, used for the substrate of braided packing or as the reinforcing material for sealing materials.
Bolts with temperatures above 150 ° C require advanced disc spring pretensioning technology. It is recommended to use this series as much as possible at operating temperatures below 300 or around and corrosive media
