PTFE गस्केट

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.

फाइदा

उच्च तापमान प्रतिरोध-काम तापमान 250 reach पुग्न सक्छ।

कम तापमान प्रतिरोध-राम्रो यांत्रिक क्रूरता छ; तापनि तापक्रम -196 drops मा घट्छ भने, यो 5% लम्बाइ कायम राख्न सक्नुहुन्छ।

जंग प्रतिरोध-यो धेरै रसायन र विलायक को लागी निष्क्रिय छ, र बलियो एसिड र क्षार, पानी र विभिन्न कार्बनिक विलायक को सामना गर्न सक्छ।

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.

विद्युत गुण Polytetrafluoroethylene कम ढांकतात्मक लगातार र एक व्यापक आवृत्ति दायरा मा ढांकता घाटा छ, र उच्च ब्रेकडाउन भोल्टेज, मात्रा प्रतिरोधकता र चाप प्रतिरोध छ।

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.

वायुमण्डलीय बुढ्यौली प्रतिरोध: विकिरण प्रतिरोध र कम पारगम्यता: वातावरण को लागी दीर्घकालीन जोखिम, सतह र प्रदर्शन अपरिवर्तित रहन्छ।

गैर-दहनशीलता: अक्सिजन सीमा सूचकांक below ० भन्दा तल छ।

एसिड र क्षार प्रतिरोध: बलियो एसिड, बलियो क्षार र कार्बनिक विलायक मा अघुलनशील।

ओक्सीकरण प्रतिरोध: बलियो oxidants द्वारा जंग प्रतिरोधी।

अम्लता: तटस्थ।

PTFE को यांत्रिक गुणहरु अपेक्षाकृत नरम छन्। एक धेरै कम सतह ऊर्जा छ।

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.
