Description

PTFE ( polytetrafluorethylen ) – is fluoropolymer with excellent characteristics.
· High continual temperature resistance until 250°C (for a short time 280°C), temperature degradation start at about 350°C
· Good frost resistance until –200°C (PTFE foil are flexibility to –150°C)
· PTFE material has high tensile strength, good flexibility including minus temperature, at high wing loading is not to be crush. (Cold fluid polymer)
· With its non-polar structure is one of the best dielectric materials.
· Excellent chemical resistance in al range of pH. It is stable in boiling nitric acid, aqua-regia, resistance to halogens, alkali and majority organic solvents. Not until temperature 200°C is attack melting alkaline metals, fluorine and fluorine hydrocarbons.
· It is extreme resistance climatic conditions during 30 years.
· Next its invaluable character with low friction coefficient, therefore it use for produce bearing.
· It don’t stick with all plasticators and it has markedly anti-adhesive properties.
· It don’t resistance high energetic radiation (depolymerize).
