Characteristics of PTFE sheet and PTFE rod2018-07-12
Teflon plate English name: polytetrafluoroethylene. PTFE sheet is a kind of PTFE-containing polymer chemical material. It is widely used in packaging, electronic and electrical, chemical energy, corrosion-resistant materials. Teflon high-performance special coating is fluorine based on polytetrafluoroethylene as matrix resin. Paint, the English name is Teflon, because of the pronunciation, it is often called Teflon, Teflon, Teflon, Teflon, etc. (all Teflon transliteration).
Characteristics of PTFE plate and PTFE rod:
1. The temperature range is very wide (from -200 degrees Celsius to +260 degrees Celsius).
2. Basically resistant to all chemicals except some fluorides and alkaline liquids.
3. Excellent mechanical properties including anti-aging properties especially for bending and swing applications.
4. Outstanding flame retardancy (according to ASTM-D635 and D470 test procedures, it is classified as a flame retardant material in air.
5. Excellent insulation properties (regardless of frequency and temperature)
6. The water absorption rate is extremely low, and it has a series of unique properties such as self-lubricating and non-stickiness.
Application areas of PTFE sheets:
PTFE sheets can be used in seals/gaskets, rings, wear plates/seats, insulation parts, corrosion resistant industries, mechanical parts, linings, oil and gas, petrochemical industry, chemical industry, equipment Manufacturers, etc.
Mainly in view of the five characteristics of polytetrafluoroethylene sheet:
Low temperature resistance - especially the PTFE plate has good mechanical toughness; even if the temperature drops to -196 ° C, it can maintain 5% elongation.
Corrosion resistance - inert to most chemicals and solvents, tetrafluoroethylene, strong acid and alkali, water and various.
Weather resistance - PTFE has an aging life in plastics.
In the high-tetrafluoroethylene PTFE plate material in the material.
Non-adhesive—The surface tension in the PTFE body material does not adhere to any, and its mechanical properties have a very small coefficient of only 1/5 of the polycondensation, which is an important feature of the perfluorocarbon surface. Since the fluorine-carbon chain is extremely low in molecular interaction, the polytetrafluoroethylene has no viscosity.
