Customized Heterotype Rubber Flange Gasket PTFE EPDM Valve Rubber Seal
Introduction:
The patented rubber back cushion structure attached to a reinforced rubber back cushion with a high-performance material has a wide range of flexible life and can operate in most chemical environments. Chemical inertness and temperature stability, long service life means more time to change the frequency of low, so reduce maintenance costs, complete specifications, suitable for most brands of pumps and with the most specifications size.
Diaphragm valve rubber PTFE composite diaphragm is made of advanced EPDM or NBR as the main body, in its effective sealing composite part by special activation processing of 100% pure PTFE shell, mainly suitable for food, chemical, pharmaceutical and other industries.

Eight properties of EPDM material:
Details of PTFE material performance:
High temperature resistance: long-term use temperature 200~260 degrees;
Low temperature resistance: still soft at -100 degrees;
Corrosion resistance: resistance to aqua regia and all organic solvents;
Weather resistance: strong aging life in plastic;
High lubrication: with the smallest friction coefficient in plastic (0.04);
Instickiness: having less surface tension in solid materials and not adhering to other substances;
Non-toxic: with physiological inertia;
Excellent electrical performance: it is an ideal insulation material, a thick layer of newspaper can block 1480V high pressure; smoother than the ice.
