Tubing. Tubing for a wide range of working environments: including versions for the food industry, flame-retardant, PWIS-free or media-resistant designs. Specified types in accordance with ATEX directive for potentially explosive atmospheres.
As well as having the lowest coefficient of friction of any solid (0.05-0.08), PTFE has a very high upper temperature limit of 260°C. PTFE in its form can be easily deformed by high loads and compressive forces. To minimise this additives such as glass (usually creamy colour), Bronze (usually brown colour), Carbon (black colour) are added prior to moulding. PTFE can also be chemically etched on one surface …

The main disadvantage of PFA is that it is more expensive than PTFE and FEP. PFA is ideal for appliions that require a higher purity grade, excellent chemical resistance and a high working temperature. This fluoroplastic is widely used in medical tubing, heat exchangers, semi-conductor baskets, pumps and fittings, and valve liners.
PTFE (polytetrefluoroethylene) is a soft, low friction fluoropolymer with outstanding chemical resistance and weathering resistance. PTFE is stable at temperatures up to 500 o F and it is often used in high temperature environments. PTFE also has excellent electrical insulating properties.
Solvent resistance of PTFE PTFE is insoluble in almost all solvents at temperatures up to about 300°C. Fluorinated hydrocarbons cause a certain swelling which is however reversible; some highly fluorinated oils, at temperatures over 300°C, exercise a certain dissolving effect upon PTFE. Resistance of PTFE to atmospheric agents and light
Teflon conveyor belt, also known as Teflon conveyor belt, Teflon mesh conveyor belt, PTFE conveyor belt, etc., has weather resistance and anti-aging. After p
PTFE (Teflon®) Best chemical resistance, lowest friction coefficient and high temperature range (-200⁰C + 260⁰C) Good dielectric strength; Excellent weather resistance and insensitive to UV rays; Poor mechanical properties. Food Safe (non-toxic) Used for O-rings, valve seats, stem seals, gaskets, insulators, guides, bellows
Low Temperature Properties of Polymers Introduction Most plastics at room temperature show their familiar properties of flexibility (a low Young’s modulus) and high resistance to cracking but when the temperature decreases this can change rapidly and many common plastics become brittle with low …
