Product Details

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).
