Virgin PTFE
Unfilled PTFE for chemical-contact and electrical-insulation components. Review creep, sustained loading and purity documentation before selecting the grade.
Review gradeMaterial composition & selection
PTFE Grades
Choose PTFE by composition and function. Compare unfilled, filled and expanded constructions against the load, contact media, motion and electrical requirements of the component.
Select the Material Family
A grade defines the material. A product drawing defines the shape made from that material. Select both for a complete procurement requirement.
Filled PTFE
Compare filled PTFE compounds for wear, load, creep and thermal behavior. Select the actual filler system and composition rather than a generic filled grade.
Review gradeGlass Filled PTFE
Glass-filled PTFE for components where wear and deformation under load drive grade selection. Include the mating surface and chemical exposure in the review.
Review gradeCarbon Filled PTFE
Carbon-filled PTFE compounds for sliding and seal components. Identify the carbon form, any graphite blend and the required electrical behavior.
Review gradeBronze Filled PTFE
Bronze-filled PTFE for loaded wear and sealing components. Evaluate the metallic filler against the fluid, counterface and electrical requirements.
Review gradeGraphite Filled PTFE
Graphite-filled PTFE for sliding interfaces and seal components. Select the formulation with the counterface, lubrication and contamination limits in view.
Review gradeExpanded PTFE
Expanded PTFE sheet and joint-sealant forms for compliant static sealing. Specify flange condition, compression and the material construction for the joint.

Composition First, Component Fit Next
Unfilled PTFE, a specified filled compound and expanded gasket material address different duties. A grade label alone does not define the finished part or an assembly rating.
Material grades and supplied constructions
Glass-filled PTFE is a compound. PTFE coated fiberglass fabric is a textile with a coated surface. Their shared material names do not make them interchangeable.
Use the product catalog for fabrics, tapes, films and belts; use this grade library for the polymer construction specified in a PTFE component.
