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.

faida

Upinzani wa joto-joto linaweza kufikia 250 ℃.

Upinzani mdogo wa joto-ina ugumu mzuri wa kiufundi; hata ikiwa joto hupungua hadi -196 ℃, inaweza kudumisha urefu wa 5%.

Kutu ya kutu-Haina kemikali nyingi na vimumunyisho, na inaweza kuhimili asidi kali na alkali, maji na vimumunyisho anuwai anuwai.

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.

Sifa za umeme Polytetrafluoroethilini ina upungufu wa dielectric mara kwa mara na upotezaji wa dielectri katika masafa anuwai, na ina voltage kubwa ya kuvunjika, upunguzaji wa kiasi na upinzani wa 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.

Upinzani wa kuzeeka wa anga: upinzani wa mionzi na upenyezaji mdogo: mfiduo wa muda mrefu kwa anga, uso na utendaji hubadilika bila kubadilika.

Isiyowaka: Kiwango cha kikomo cha oksijeni kiko chini ya 90.

Upinzani wa asidi na alkali: hakuna katika asidi kali, alkali kali na vimumunyisho vya kikaboni.

Upinzani wa oksidi: sugu kwa kutu na vioksidishaji vikali.

Ukali: Si upande wowote.

Mali ya mitambo ya PTFE ni laini. Ina nishati ya chini sana ya uso.

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.
