Filled PTFE product is manufactured by moulding method with filled PTFE resin. Filled PTFE resin is manufactured by compounding PTFE granular resin with different kinds of fillers, such as glass fiber, carbon fiber, bronze and also lubricating materials like graphite, molybdenum disulfide. Those PTFE compounds have the following advantages over unfilled.
