Modified PTFE Powder — Glass, Carbon, Graphite, Bronze & More
Peflon has custom-formulated modified (filled) PTFE since 2008. Every formulation is rigorously tested, passes REACH and complies with EU regulations — typical delivery within 10 working days.
What is Modified PTFE?
Peflon modified PTFE changes the structure or performance of conventional polytetrafluoroethylene (PTFE, CAS 9002-84-0) by physical or chemical means to enhance its characteristics for more demanding applications. By adding fillers to conventional PTFE, the resulting material keeps excellent high-temperature resistance, chemical resistance, a low coefficient of friction and self-lubrication.
Fillers such as glass, carbon, graphite, bronze and MoS₂ raise wear resistance, reduce creep (cold flow) and can add electrical conductivity — see general PTFE property data. Through modification, PTFE’s properties are optimized to meet specific industry requirements.
Types of Modified Methods
Physical Modification
Changes the physical form of the PTFE structure without altering its chemical composition. Filled modified PTFE powder improves properties by adding filler materials.
Surface Modification
Surface treatment enhances surface activity or adhesion so the PTFE powder bonds more readily to other materials in coatings and composites.
Types of Modified PTFE Powder
Nine filler systems — pick by the property you need: wear resistance, low friction, conductivity, compressive strength or thermal stability.
POB Modified PTFE
Abrasion resistance for demanding wear service.
PEEK Modified PTFE
Higher mechanical strength and load capacity.
PI Modified PTFE
Improved mechanical strength and thermal stability.
PPS Modified PTFE
Heat stability and chemical resistance.
Modified PTFE Applications
Peflon modified PTFE — enhanced with fillers for higher mechanical strength and wear resistance — is used in seals, bearings, sliding parts, high-temperature and corrosive environments, electronics, medical, aerospace and automotive.
Molding Sheet
Chemical equipment, seals, insulating materials and mechanical gaskets.
PTFE Rod
Corrosion-resistant parts, seals and insulators for chemical, mechanical and electrical industries.
Cables
Insulating parts for cables with better electrical insulation and anti-pollution properties.
Sliding Parts
Bearings, sliders and guide rails for low-friction service.
Sealing Tape
Pipe-thread sealing across chemical, petroleum and natural-gas industries.
PTFE Skived Film
Widely used across electronic, electrical, chemical and mechanical industries.
Modified PTFE — Frequently Asked Questions
What is modified (filled) PTFE and why use it?
Modified PTFE is virgin PTFE blended with fillers such as glass, carbon, graphite, bronze or MoS₂. Fillers dramatically improve wear resistance, reduce creep (cold flow) and can add conductivity or compressive strength — while keeping PTFE’s chemical resistance and low friction.
Which filler should I choose?
Glass raises wear resistance and cuts creep for general service; carbon adds wear and some conductivity; graphite gives the lowest friction and self-lubrication; bronze maximizes wear resistance, compressive strength and heat transfer; MoS₂ lowers friction. Tell us your load, speed and medium and we will match a filler.
Does filling change PTFE’s chemical resistance?
Inert fillers like glass and graphite keep most of PTFE’s chemical resistance; metallic fillers such as bronze are attacked by strong acids and bases, so grade selection must consider the service medium.
How is modified PTFE supplied and processed?
As free-flowing powder for compression molding and sintering into rod, tube, sheet, plate and seals, or for skiving into film and tape. Filler loading is customized to the target property.
What filler loadings are typical?
Common loadings run from a few percent up to about 40% by weight depending on the filler and the property target. Higher loadings raise wear resistance and stiffness but can reduce elongation — we tune the ratio to your part.
Is Peflon modified PTFE PFOA-free and compliant?
Yes — Peflon modified PTFE is PFOA-free, passes REACH testing and complies with EU regulations, with per-batch documentation available on request.
