Ptfe Thread Seal Tape For Gas

10(001).jpg

PTFE-Tape with lower density <0,70g/cm3 are applied for the sealing of threaded joints on systems for water, compressed air, cooling and steam systems and hydraulic systems. It is applicable on all types of materials (iron, metal, plastic, fibre etc.). Thread seal tape in general is also suitable on systems where heavy hygiene requirements are made (hospitals, food industry etc.) and can thus be used for drinking water and domestic water

It is used for sealing of threaded joints on installations with especially gas and oxygen, while Sealrite may be used on all types of installations with gas and lager threads.

The high density taps described here are applied for the sealing of threaded joints on systems for water, compressed air, cooling and steam systems and hydraulic systems. It is applicable on all types of materials (iron, metal, plastic, fibre etc.) It is suitable for about all tubing materials like iron, stainless steel, cast metals, plastics, fibre etc.

The relative molecular mass of polytetrafluoroethylene is relatively large, with the lower being 100,000 and the higher being more than 10 million, generally millions (the polymerization degree is on the order of 104, while polyethylene is only 103 ). The general crystallinity is 90 ~ 95%, melting temperature 327 ~ 342 ℃. CF2 units in Polytetrafluoroethylene molecules are arranged in a serrated shape. Since the radius of fluorine atoms is slightly larger than that of hydrogen, adjacent CF2 units cannot be completely cross-oriented, but form a spiral twisted chain, fluorine atoms cover almost the surface of the entire polymer chain. This molecular structure explains various properties of polytetrafluoroethylene. When the temperature is lower than 19℃, a 13/6 helix is formed. Phase change occurs at 19℃, and molecules are slightly untied to form a 15/7 helix.
Although the breaking of carbon-carbon bond and carbon-fluorine bond in all fluorocarbon needs to absorb 346.94 and 484.88kJ/mol respectively, the depolymerization of polytetrafluoroethylene to produce 1mol tetrafluoroethylene only needs 171.38kJ of energy. Therefore, when cracking at high temperature, Polytetrafluoroethylene is mainly depolymerization into tetrafluoroethylene. The weight loss rate (%) of polytetrafluoroethylene at 260, 370 and 420 ℃ is 1 × 10-4, 4 × 10-3 and 9 × 10-2 per hour respectively. It can be seen that polytetrafluoroethylene can be used at 260 ℃ for a long time. Since highly toxic by-products such as fluorophosphate and perfluoroisobutylene are also produced during pyrolysis, special attention should be paid to safety protection and prevention of polytetrafluoroethylene from contacting open flames.
