One of Hottest for PTFE Gasket Wholesale to Denmark

PTFE gasket is manufactured by molding method with PTFE granular resin. Compared with other plastic, PTFE has a superior properties against chemicals and temperature. Because of such excellent properties, PTFE gasket has a wide application as a sealing material.

Technical Data Sheet

Application Area

As a sealing material, PTFE gaskets can be used in flange joint of various equipments and pipes in chemical industry, food producing industry, medicine industry and so on. It can bear the most bitter chemical medium, and has good anti-creeping performance. The unloaded operating temperature range is -180~+260℃.

Modular back-ups, MB profile, are specifically designed to compliment the PolyPak profiles. To help make the selection and ordering of the correct part number for the MB profile easy and efficient, the part numbering system used is very similar to that of the PolyPak. By formulating high modulus blends of Molythane (4617) and PolyMyte (4652), Parker has ensured that MB back-ups can be used with either type of base sealing material while maintaining the expected temperature range and fluid compatibility. The robust design ensures pressure ratings up to 10,000 psi are met.

Back-up rings are the most common anti-extrusion devices in dynamic sealing. They provide simple solutions to safely increase system pressure or solve an existing seal extrusion problem. Back-up rings function by positioning a more robust material adjacent to the extrusion gap, taking the seal’s place and providing a barrier against high pressures. Back-ups can be used to offset the reduced pressure rating effects of wear rings or to improve seal life at increased pressures. They can also be used to protect seals against pressure spikes, or to ensure seal performance at higher temperatures.
