Product Description

                                                                                     PTFE Rod and Filled PTFE products


PTFE is a high performance polymer that can make various products owing to its versatile properties. Some of the most astounding properties of PTFE that make it amendable to versatile industrial use include exceptional resistance to weather, Chemical inertness, resistance to heat, excellent electrical insulation and more.

PTFE is available in virgin & filled compounds to improve the basic characteristics to match very diverse applications & optimization for specific end uses. The grade of PTFE is selected from Virgin & Filled grades of PTFE, based on required property for required service conditions / applications. The selection guide elaborates various grades of PTFE & Filled PTFE, filler content in PTFE, basic properties & relevant service conditions / End applications. 

Common used Fillers for PTFE: Glass fiber, molybdenum disufide, graphite, bronze powder, silica, carbon fiber and so on.

PTFE rods can be used to make various types of seals, back up rings, washers, and other components.
