Synthetic fiber yarn, well know by phenolic fibre, the cross-linked organic polymer fiber material is used as the skeleton. The fiber does not melt or burn in a flame at 2500°C. It has good thermal insulation performance and excellent corrosion resistance. Organic cross-linked polymer fiber is based on this fiber, processed by the company’s unique PROIM process, and processed by imported international high-speed braiding machines. It is a compression packing with excellent performance. It is especially suitable for packing seals of reciprocating or rotating machinery under high linear velocity, high pressure, containing suspended particles and corrosive media.
