PTFE gasket

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.

Fanoherana ny hafanana avo-mety hahatratra 250 ℃ ny mari-pana miasa.

Fanoherana ny hafanana ambany – manana hamafin’ny mekanika tsara; na dia midina hatramin’ny -196 ℃ aza ny mari-pana, dia afaka mitazona ny elongation 5% izy io.

Fanoherana ny harafesina-Tsy azo ihodivirana amin’ny ankamaroan’ny akora simika sy solvents ary mahazaka asidra mahery sy alkaly, rano ary solvents organika isan-karazany.

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.

Toetran’ny herinaratra Polytetrafluoroethylene dia manana fatiantoka diélectrique ambany sy fatiantoka diélectrique amin’ny halaviran’ny hatetika, ary manana herinaratra mihena be, fanoherana ny haavon’ny boky ary fanoherana ny 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.

Fanoherana ny fahanteran’ny atmosfera: fanoherana ny taratra sy ny tsy fetezena ambany: maharitra maharitra amin’ny atmosfera, tsy miova ny velarana sy ny fahombiazany.

Tsy azo dorana: ambany noho ny 90 ny mari-pahaizana fetran’ny oxygen.

Fanoherana ny asidra sy ny alkaly: tsy afaka amin’ny asidra mahery, alkaly mahery ary solvents organika.

Fanoherana oksizena: mahatohitra fahasimbana ataon’ny oxidants mahery.

Asidra: tsy miandany.

Ny toetra mekanika an’ny PTFE dia malefaka ihany. Manana angovo ambony ambany be.

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.
