改性PTFE高温组合垫：由全新一级细颗粒料为母料，填充一定比列的石墨、碳纤维、对位聚苯、玻纤等改性材料，使该产品能在-180摄氏度到300摄氏度高温下正常工作，并且增加其抗压性。其主要产品有石墨阀座、PPL阀座、聚苯酯阀座等。其特征：它具有优良的化学稳定性、耐腐蚀性、密封性、高润滑不粘性、电绝缘性和良好的抗老化耐力。填充改性四氟材料对于耐磨耗、导热、抗糯变、自润滑等方面比纯聚四氟乙烯制品有较明显的提高。
Modified PTFE High Temperature composite Gasket
The modified materials such as graphite, carbon fiber, counter-position polystyrene, glass fiber and so on are filled with a new class of fine particles,enable the product to work properly at -180C to 300C,and increase its compressibility.Its main products are graphite seat, PPL seat, polystyrene seat and so on.Its characteristics:It has excellent chemical stability, corrosion resistance, sealing, high lubrication non-stickiness, electrical insulation and good anti-aging endurance.The filling modified Teflon has a better resistance to wear, heat conduction, waxy change and self-lubrication than pure PTFE.
