We can offer all kinds of ptfe gaskets made of virgin PTFE(standard and modified), and filled PTFE(compound).

The modified virgin PTFE can increase the service life of sealing rings to 300% longer than standard PTFE theoretically. It is the new-generation PTFE material with high reliability which greatly improves on the performance of conventional PTFE, while possessing the same excellent characteristics of conventional PTFE, such as heat resistance and chemical resistance, It also has improved creep resistance and greater durability under severe conditions when used in applications such as valve seats, packing, gaskets and bellows .

Material range:

Include virgin& all filled grades PTFE and others from Dupont, Daikin, 3M, 3F, etc.

Virgin PTFE100% PTFE
Filled PTFEFiller Type
Inorganic fillerGlass fiber, Graphite, Bronze, Carbon fiber, MoS2
