PTFE gasket

PTFE gaskets have excellent properties of creep resistance, cold flow resistance, ultra-low temperature resistance, no pollution, and easy installation and disassembly. Under a small pre-tightening force, it can withstand considerable internal pressure even in a pressure fluctuation environment. It is very suitable for rough or unevenly worn and fragile glass-faced flanges and temperature-changing sealing occasions. We can choose Gore, Klinger, Garlock, Sealon and other expanded PTFE sheets for customers to produce the required gaskets for customers.

avantaj

Rezistență la temperaturi ridicate – temperatura de lucru poate ajunge la 250 ℃.

Rezistență la temperaturi scăzute – are o rezistență mecanică bună; chiar dacă temperatura scade la -196 ℃, poate menține alungirea cu 5%.

Rezistență la coroziune – Este inertă pentru majoritatea substanțelor chimice și solvenților și poate rezista la acizi și alcali puternici, apă și diferiți solvenți organici.

Weather resistance-has excellent aging life in plastics.

High lubrication-is the low coefficient of friction in solid materials.

Non-adhesion-it means that the surface tension in the solid material is small and does not adhere to any substance. Its mechanical properties have a very small friction coefficient, which is only 1/5 of that of polyethylene. This is an important feature of the perfluorocarbon surface. In addition, because the fluorine-carbon chain intermolecular forces are extremely low, PTFE is non-sticky.

Non-toxic and harmful-with physiological inertia, as an artificial blood vessel and organ implanted in the body for a long time without adverse reactions.

Proprietăți electrice Politetrafluoretilena are o constantă dielectrică scăzută și pierde dielectric într-o gamă largă de frecvențe și are tensiune de rupere ridicată, rezistivitate de volum și rezistență la arc.

Radiation resistance Polytetrafluoroethylene has poor radiation resistance (104 rad), and it degrades after being exposed to high-energy radiation, and the electrical and mechanical properties of the polymer are significantly reduced. Application Polytetrafluoroethylene can be formed by compression or extrusion processing; it can also be made into water dispersion for coating, dipping or making fibers. PTFE is widely used as high and low temperature resistant, corrosion resistant materials, insulating materials, anti-stick coatings, etc. in nuclear energy, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textiles, food and other industries.

Rezistență la îmbătrânire atmosferică: rezistență la radiații și permeabilitate redusă: expunere pe termen lung la atmosferă, suprafața și performanța rămân neschimbate.

Incombustibilitate: indicele limită de oxigen este sub 90.

Rezistență la acizi și alcalii: insolubilă în acizi puternici, alcali puternici și solvenți organici.

Rezistență la oxidare: rezistentă la coroziune de către oxidanți puternici.

Aciditate: Neutru.

Proprietățile mecanice ale PTFE sunt relativ moi. Are o energie de suprafață foarte redusă.

Polytetrafluoroethylene (F4, PTFE) has a series of excellent performance: high temperature resistance-long-term use temperature of 200~260 degrees, low temperature resistance-still soft at -100 degrees; corrosion resistance-resistance to aqua regia and all organic solvents; Weather resistance-aging life in plastics; high lubrication-with a small coefficient of friction (0.04) in plastics; non-stickiness-with low surface tension in solid materials without adhesion of any substances; non-toxic-with physiological inertness; excellent electrical properties , Is an ideal C-level insulating material.
