此垫片是由GORE戈尔PTFE的膨体聚四氟乙烯材料切割或冲压而成，膨体四氟材料（eptfe)它是将聚四氟乙烯膨化成为一种具有强韧而多孔性的独特材料，它高度纤维化，这种材料不但保持了聚四氟乙烯本身独特的性能--极佳的化学稳定性（不受一般化学品的影响）；极低的摩擦系数；较广阔的操作温度；不会老化永久耐用；现在它多纤维的结构使其作为密封产品具有超乎想象的坚韧性，更重要的是他从根本上解决了其它类型四氟密封材料的通病--蠕变和冷流，与纯四氟垫片和填充四氟垫片相比性能大为改善，另外，易于切割，便于安装，使用寿命长等特性使它能在几乎所有的密封场合中得到实际应用。这无疑是一项了不起的革命。
The gasket is made of a expanded PTFE material cut or punched by GORE PTFE,EPTFE is a unique material with strong and porous properties by puffing PTFE,It's highly fibrotic,this material not only maintains the unique properties of PTFE--Excellent chemical stability (Unaffected by general chemicals);Very low coefficient of friction;Broader operating temperature;will not age permanently durable;Now its multifibre structure makes it incredibly tough as a sealing product,More importantly, he has fundamentally solved the common problems of other types of Teflon sealing materials -- creep and cold currents,Compared with pure PTFE gasket and filled PTFE gasket, the performance is improved greatly,In addition, easy to cut, easy to install,Its long service life enables it to be applied in almost all sealing situations.This is undoubtedly a remarkable revolution.
