What is PTFE Molding Grade?
PTFE (Polytetrafluoroethylene, CAS 9002-84-0) molding grade resin is a specialized form of PTFE granular powder — a tetrafluoroethylene polymer — explicitly engineered for compression molding. It offers increased adaptability in shaping products and creating stock shapes like rods, tubes and sheets. High-pressure shaping in molds produces parts with exceptional chemical resistance, low friction and dimensional stability for the most demanding industrial service.
Features & Benefits of Peflon™ PTFE Granular Molding Powder
Engineered for compression molding lines — balanced flow, clean processing and superior finished-part performance across sealing, bearing and chemical-service applications. See independent PTFE material properties for baseline data.
Uniform Flow
Controlled granular flow fills molds evenly — consistent density across thick and thin sections.
Non-Stick Surface
Exceptional release properties — ideal for applications where preventing adhesion is critical.
Chemical Resistance
Resistant to virtually all acids, bases, fuels and solvents — preserves integrity in hostile media.
Wide Temperature Range
From cryogenic −200 ℃ to +260 ℃ continuous service without loss of mechanical or electrical properties.

Teflon Material Applications
Peflon™ PTFE molding-grade granular powder is compressed and shaped under controlled conditions — producing precise, customized rods, tubes, sheets, bellows, piston rings, valve plugs, diaphragms, gaskets and seals.
Teflon Sheets
Compressed and shaped via skiving or rolling into thin, flat sheets.
Rods
Cylindrical stock for bearings, insulators and mechanical/electrical/chemical components.
Bellows
Accordion-like structures for pumps, valves and piping — flexibility under expansion/contraction.
Valve Plugs, Diaphragms
For industrial valves and pumps in fluid handling systems.
PTFE Tubes
Extruded or molded tubes in various diameters and lengths.
Skived Films & Sheets
Sliced from PTFE resin blocks into precise-thickness flat sheets — aerospace, food, pharma.
Piston Rings
Precision-molded or cut rings for sealing pistons in automotive, hydraulic and machinery.
Expansion Joints
Layered PTFE assemblies for bridges and piping systems under thermal expansion.
PTFE Granular Molding Powder Processing
From raw resin to finished part — the compression-molding workflow for PTFE stock shapes like rods, tubes, sheets and billets.
1 · Material Selection
Select the right virgin or filled PTFE molding grade by particle size, molecular weight and end-use requirement.
2 · Mould & Die Selection
Choose a mould sized to the target billet or part, matched to press tonnage and shrinkage allowance.
3 · Compression Molding
Cold-press the PTFE resin in the mould under high pressure to form a dense, uniform preform.
4 · Sintering
Sinter the preform above 327 °C to fuse the particles into a solid, void-free billet, then cool under control.
5 · Semi-Finished Billet
Cooled rods, tubes, sheets and billets — dimensionally stable stock shapes ready for finishing.
6 · CNC Machining & Turning
Finish to final part tolerances by CNC machining, turning, skiving or cutting.
