Filled PTFE resin is manufactured by compounding PTFE granular resin with fillers of many differents kinds. Amongst the many fillers suitable for compounding with PTFE, glass fiber, carbon fiber, Bronze and also lubricating materials like graphite, molybdenum disulphide, have been widely used in large scale production, Broadly speaking PTFE compounds have the following advantage over unfilled.Filled compound and Content by wtTensie strength MPa(min)Ultimate strength %(min)Compresive strength MPa(min)20% glass fiber101201625% glass fiber101001620% glass fiber 5% graphile101201660% Bronze10802015% carbon fiber111301624% Bronze 12% glass fiber 6% graphile91001615% glass fiber 10% Polyikmide 5% graphile1012016.7PTFE spiral wound gasket is corrosion resistant and high pressure product.  By winding metal with PTFE is model PTFE spiral wound gasket.
