       Filled PTFE gasket is manufactured by moding method with filled PTFE resin. Filled PTFE resin is manufactured by compounding PTFE granular resin with fillers of many differents kinds. Amongst the many fillers suitable for compounding with PTFE, glass fiber, carbon fiber, Bronze and also lubricating materials like graphite, molybdenum disulphide, have been widely used in large scale production, Broadly speaking PTFE compounds have the following advantage over unfilled.

      PTFE spiral wound gasket is corrosion resistant and high pressure product.  By winding metal with PTFE is model PTFE spiral wound gasket. It could fix the outer ring or inner ring, even with outer and inner ring.

 

PTFE is the most representative fluoric resin and having very unique properties showing superior heat / low temperature / chemical / friction / adhesion resistance along with excellent electrical property.

The material is widely used for the applications that require simultaneous multi properties (i.e Heat resistance + electrical property, Chemical resistance + Heat resistance, Non-adhesive + heat resistance) and, more particularly, for the applications that require chemical / agent resistance in chemical or semi-conductor industry.

 

Low friction

The product shows the lowest friction coefficient among all solid materials.

Superior chemical resistance

The product is stable and safe against almost of all chemicals and agents.

Electrical property

With low electric permittivity loss factor, the product holds superior electrical property and is stable

Fire resistance

The product offers extraordinary resistance to high temperature and flames because it has a very high melting point and auto-ignition Temperature, as well as exceptional thermal degradation thresholds. Teflon's flame propagation characteristics, such as rate of heat release and smoke generation is very low Friction and Wear
