Products Details

PTFE ring size identification

Polytetrafluoroethylene (PTFE), with excellent chemical stability, corrosion resistance, sealing, high lubricating non-stick properties, electrical insulation and good aging resistance.

PTFE BACK-UP RING&WASHER is generally used in the sealing of corrosion-resistant pipelines, containers, pumps, valves, and radar, high-frequency communication equipment, and radio equipment with high performance requirements.

Products Advantages

High temperature resistance – working temperature up to 250 ℃.

Low temperature resistance – good mechanical toughness; 5% elongation can be maintained even when the temperature drops to -196°C.

Corrosion resistance – inert to most chemicals and solvents, strong acid and alkali resistance, water and various organic solvents.

Weather Resistant – Has the best aging life of any plastic.

High Lubrication – The lowest coefficient of friction among solid materials.

Non-stick – is the smallest surface tension in a solid material that does not stick to anything.

Non-toxic – It is physiologically inert, and it has no adverse reactions when it is implanted in the body as an artificial blood vessel and an organ for a long time.

Atmospheric aging resistance: radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.

Incombustibility: The oxygen limit index is below 90.

Acid and alkali resistance: insoluble in strong acids, alkalis and organic solvents (including magic acid, ie fluoroantimony sulfonic acid).

Oxidation resistance: can resist the corrosion of strong oxidants.

Acidity and alkalinity: Neutral.

The mechanical properties of PTFE are relatively soft. Has very low surface energy.we are able to supply top quality items, aggressive price and greatest buyer assistance.
