PTFEガスケット

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.

利点

高温耐性-作動温度は250℃に達する可能性があります。

低温耐性-優れた機械的靭性を備えています。 -196℃まで下がっても5％の伸びを維持できます。

耐食性-ほとんどの化学薬品や溶剤に対して不活性であり、強酸や強アルカリ、水、さまざまな有機溶剤に耐えることができます。

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.

電気的特性ポリテトラフルオロエチレンは、広い周波数範囲で低い誘電率と誘電損失を持ち、高い絶縁破壊電圧、体積抵抗率、およびアーク抵抗を備えています。

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.

大気老化耐性：耐放射線性および低透過性：大気への長期暴露、表面および性能は変化しません。

不燃性：酸素限界指数は90未満です。

耐酸性および耐アルカリ性：強酸、強アルカリおよび有機溶剤に不溶。

耐酸化性：強力な酸化剤による腐食に耐性があります。

酸性度：中性。

PTFEの機械的特性は比較的柔らかいです。 表面エネルギーが非常に低い。

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.
