Product Description

Factory Price White Expanded PTFE Round Sealing Cord Rope
 

Product Description

Expanded PTFE Rope  is made of 100% PTFE of puffed PTFE material cut or punched. Expanded PTFE material (eptfe) expands PTFE into a unique material with strong, tough and porous properties and is highly fibrotic.

It not only maintains the unique properties of PTFE itself - excellent chemical stability (not affected by general chemicals); extremely low coefficient of friction; wider operating temperature; non-aging and permanent durability;
Now its multi-fiber structure gives it an unimaginable tenacity as a sealing product, and more importantly, it fundamentally solves the common problems of other types of sealing materials -- creep and cold flow, which greatly improves the performance compared with pure gaskets and filled gaskets. In addition, it is easy to cut, easy to install, and has a long service life. This is undoubtedly a remarkable revolution.

1. Easy to cut, asy to install can be mechanical stamping or manual cutting into any shape of the gasket, let your work become easier.

2. It's suitable for rough surface has unique compliance forming ability, it can produce good sealing effect on rough or damaged flange surface without increasing much pressure.
3.Extremely strong chemical corrosion resistance does not react with any chemical except for a very small number of chemicals such as fused alkali metals, tertiary nuclei, etc., and can be applied in all sealing occasions within the allowable range of temperature (315ºC), which will greatly reduce the variety and number of seals.
4.The unique high density fiber structure with good creep resistance and cold resistance, it has strong creep resistance. Its mechanical properties are very stable because it contains no adhesive and additives.
