High carbon packing made of high carbon fiber and graphite filled into material, adding lubricant. High carbonized fiber packing is manufactured by heating polyacrylonitrile fiber into carbonized fiber, which is then braided into packing after impregnation in PTFE dispersion. This high carbon packing has good heat conduction and low corrosion rate,and the price is relatively lower, so it’s generally used in dynamic sealing in the presence of weak acid or alkaline media, or media that contains few solid particle grains.
Ceramic fibre packing is braided with high quality ceramic fiber without ant impregnant. Ceramic packing is braided without any flammability component.This kind of gland Packing is static sealing packing.Ceramic fibre packing has many excellent capabilities of high strength and high temperature resistant, better insulation,incombustible,etc,It can be impregnated with graphite latex.This kind of graphite ceramic fibre packing is used in sealing of high temperature and high pressure.It can be reinforced with stainless steel or glass fibre.This will make much improvement to Ceramic Fibre Packing.
Fiberglass Braided Packing is diagonally braided from textured glass-fiber yarn, impregnated through out with PTFE emulsion, silicone-free break in lubricant. It is very dense and supple packing, good chemical resistance.
Ramie fiber packing is very soft and easy to be impregnated.It turn to be with higher strength, better corrosion and attrition resistance after impregnation of PTFE dispersion. The packing made of ramie fiber has very slim attrition to the shaft, so it’s an ideal material to be used in sea water ,clean water with low temperature, low speed, and equipment with the media of food, oil, and fruit juicy,ect.
