PTFE - an acronym for Polytetrafluoroethylene - is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials. PTFE has extremely low coefficient of friction. PTFE is generally considered a thermoplastic polymer; at 327°C it maintains a very high viscosity, thus requiring particular transformation techniques for manufacturing of finished and semi-finished goods. PTFE can be employed at any temperature from -200°C to +260°C.
and its advanced properties make it an ideal choice of material for a wide range of applications - particularly those requiring high temperature, chemical resistance and excellent slip-stick performance. PTFE has advanced properties making it an ideal choice of material for a wide range of applications. PTFE rod, PTFE sheet and PTFE tube is particularly useful where high temperature or excellent chemical resistance is required. With its low coefficient of friction PTFE also exhibits excellent slip-stick performance.
PTFE is reinforced with 25% glass fibres. The added glass fibre improves the wear properties and, to a minor degree, also the deformation strength under load while leaving substantially unchanged the electrical and chemical characteristics. However, it is important to remember that glass, has a rather poor resistance against alkalis and is easily attacked by hydrofluoric acid. The coefficient of friction is also slightly increased.
25% carbon is added to the PTFE, along with a small percentage of graphite. The carbon tends to improve - to a considerable degree - wear and deformation strength, whilst leaving the chemical resistance practically unchanged, but substantially modifying the electrical properties.
PTFE, because of the properties previously described, is used in many applications. Properties can be improved and/or modified by adding suitable fillers. The fillers most commonly used, in concentrations to suit application, are: Glass fibre, Carbon fibre, Bronze, Graphite, Molybdenum disulphide (MoS2), Metal powders, Ceramics, Metal oxides, and can also be produced using mixtures of two or more additives.
PTFE had Special performance Compared with other plastic. such as Never aging, Colleagues of high and low temperature resistance, and etc. so PTFE was widely used as a resistant high & low temperature material, corrosion-resistant materials, insulation materials in the atomic energy, defense, aerospace, electronics, electrical, chemical industry, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, food, and metallurgical smelting industry, and become irreplaceable products
