PTFE 가스켓

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.

이점

고열 저항 – 작동 온도는 250℃에 도달할 수 있습니다.

저온 저항 – 좋은 기계적 인성을 가지고 있습니다. -196℃까지 내려가도 5%의 연신율을 유지할 수 있습니다.

내식성-대부분의 화학물질 및 용제에 불활성이며 강산 및 알칼리, 물 및 다양한 유기 용제에 견딜 수 있습니다.

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.

전기적 특성 폴리테트라플루오로에틸렌은 넓은 주파수 대역에서 유전율이 낮고 유전 손실이 낮으며 내압, 체적 저항률 및 내아크성이 높습니다.

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.

대기 노화 저항: 방사선 저항 및 낮은 투과성: 대기에 장기간 노출, 표면 및 성능은 변경되지 않습니다.

불연성: 산소 한계 지수가 90 미만입니다.

산 및 알칼리 저항: 강산, 강알칼리 및 유기 용매에 불용성.

내산화성: 강한 산화제에 의한 부식에 강합니다.

산도: 중성.

PTFE의 기계적 성질은 비교적 부드럽습니다. 표면 에너지가 매우 낮습니다.

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.
