What is PTFE?
PTFE (Polytetrafluoroethylene) is a synthetic fluoropolymer of tetrafluoroethylene with a wide range of industrial and consumer applications. Discovered by Dr. Roy Plunkett in 1938, it is most commonly known by the brand name Teflon™ — famously used in non-stick cookware.

Coating Solutions
Types of PTFE Aqueous Dispersions
Peflon PTFE dispersion is widely used in cookware coating, industrial coatings, and functional surface treatments — where low friction, chemical resistance, and long-term durability are required. After high-temperature sintering, a continuous fluoropolymer film forms, providing stable performance under demanding conditions. In architectural and interior applications, materials such as acoustic felt panels are also widely used for sound absorption, thermal insulation, and decorative wall systems — offering lightweight and sustainable alternatives for commercial spaces.

Why Engineers Choose PTFE
Key Advantages
High Melting Point
Stable at high temperatures, up to 327 °C (620 °F).
Safety
Non-toxic and safe for use in consumer products.
Maintenance-Free
Easy to clean and maintain due to its non-stick nature.
Competitive Price
The lowest-cost option in the fluoropolymer family (vs. FEP, PFA, ETFE, PCTFE).
High Density
PTFE density reaches 2.2 g/cm³.
Hydrophobic
Repels water effectively — stays dry even under prolonged exposure.
Low Friction
One of the lowest coefficients of friction among solid materials.
Chemical Resistance
Resistant to almost all chemicals — ideal for industrial applications.
Electrical Insulation
Excellent insulator — widely used in electrical components.

Processing
The Manufacturing Process of PTFE
PTFE can be processed in several ways — compression molding, paste extrusion, ram extrusion, electrostatic spraying, impregnation, coating, and sintering. Different finished products require different processes; choose the right method with our technical support.-
Impregnation
For PTFE dispersion to produce PTFE-coated fiberglass and architectural membranes. -
Paste Extrusion
PTFE fine powder blended with additives, then paste-extruded into sealing tape, wire insulation and more. -
Ram Extrusion
For free-flow PTFE resin and pre-sintered resin — used to produce rods and tubes. -
PTFE Spray Coating
For PTFE micro powder — electrostatic coating for surface treatment. -
Compression Molding
For PTFE molding powder and filler powder — then sintering the semi-products into finished shapes. -
Sintering
PTFE products require sintering at 100–300 °C before finishing.
