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.

kauntungan

Tahan suhu dhuwur – suhu kerja bisa nganti 250 ℃.

Tahan suhu sithik – duwe ketahanan mekanik sing apik; sanajan suhu mudhun nganti -196 ℃, bisa dijaga elongasi 5%.

Resistensi korosi-Ora gampang kanggo bahan kimia lan pelarut, lan tahan asam lan alkali, banyu lan macem-macem pelarut organik.

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.

Sipat listrik Polytetrafluoroethylene duwe konstanta dielektrik kurang lan kerugian dielektrik ing kisaran frekuensi sing amba, lan duwe voltase breakdown sing dhuwur, resistivitas volume lan resistensi busur.

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.

Resistensi penuaan atmosfer: resistensi radiasi lan permeabilitas rendah: ekspos jangka panjang ing atmosfer, permukaan lan kinerja tetep ora owah.

Non-combustibility: Indeks watesan oksigen luwih saka 90.

Ketahanan asam lan alkali: larut ing asam kuat, alkali kuat lan pelarut organik.

Resistensi oksidasi: tahan karat dening oksidan sing kuwat.

Asam: Netral.

Sifat mekanik PTFE cukup alus. Nduwe energi permukaan sing sithik banget.

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.
