Detailed Product Description

PTFE gasket, also named Teflon gasket abroad, is made by cutting PTFE stick, pipe and sheet into flat shape, v shape gasket or valve annulus. It is anticorrosive, anti-aging and not electric. PTFE PH value is among 0-14. It can have good mechanical strength at -100100. The pressure is 10Mpa.

Note: When the temperature is lower than -185, PTFE gasket will get brickle. Pure PTFE gasket is a kind of clean sealing product. It wont pollute any substance it touches. It is widely used in the industry of foodstuff and medicine.

Graphite filled PTFE gasket

Graphite filled PTFE gasket, also named graphite reinforced PTFE gasket or black PTFE gasket, is compounded by special-purposed materials of particular characters. It has outstanding compression, recovery and sealing performance. Its sealing and torque-keeping performance overcomes the shortcomings of traditional PTFE on the creep feature of cold flow and material. Besides, it can keep bolt load better than traditional PTFE, which not only improves long-term sealing, but also reduces flanges maintenance. Graphite filled PTFE gasket has the advantages of low fabrication factor, good compression strength and high wear resistance, so it is more widely used than traditional PTFE. Thus, it improves environment and saves cost. It is suitable for chemical industry, hydrocarbon reaction and power plant.

Fiberglass filled PTFE gasket.

Fiberglass filled PTFE gasket, also named fiberglass reinforced PTFE gasket, is compounded by special-purposed materials of particular characters. It has outstanding compression, recovery and sealing performance. Its sealing and torque-keeping performance overcomes the shortcomings of traditional PTFE on the creep feature of cold flow and material. Besides, it can keep bolt load better than traditional PTFE, which not only improves long-term sealing, but also reduces flanges maintenance. Graphite filled PTFE gasket has the advantages of low fabrication factor, good compression strength and high wear resistance, so it is more widely used than traditional PTFE. Thus, it improves environment and saves cost. It is suitable for chemical industry, hydrocarbon reaction and power plant.

Expanded PTFE gasket

Expanded PTFE gasket is high-class particular material really. It has excellent performance of creep resistance, cold-flow resistance, ultra low-temperature resistance, no pollution, easy installation and disassembly. Even in the condition of variable pressure, it can withstand much big interior pressure. So it is much suitable for coarse, brickle glass flange or variable temperature condition. We may choose Gore, Klinger, Garlock, Sealon and other expanded PTFE sheet to produce sealing gasket. The processing size of PTFE gasket is 2000mm at most. Special specification or various non-standard products are custom-made on demand.
