More flow.
Less compromise.
A relatively high melt flow rate supports faster extrusion and the processing of small-gauge wires with thin insulation walls.
High-speed extrusion resin
Thinner walls.
Bigger possibilities.
Everflon™ FEP 4630. Melt-processible fluoroplastic pellets engineered for thin-wall wire insulation, high-speed extrusion and demanding electrical applications.

Meet the material
Built for speed.
Balanced for performance.
A tetrafluoroethylene–hexafluoropropylene copolymer, supplied without additives. The original product information identifies it as meeting ASTM D2116 Type II requirements.
More flow.
Keep the signal
in focus.
Low relative permittivity and low high-frequency dissipation factor support twisted-pair constructions and low-voltage insulation.
Fluoroplastic properties.
Everyday processing.
Chemical resistance, flexibility, low moisture absorption and improved plate-out resistance combine in a conventionally melt-processible resin.
Applications
Small dimensions.
Serious capability.
Choose FEP 4630 where thin sections, electrical performance and efficient melt processing come together.
Wire & cable insulation
Small-diameter, thin-wall insulation for small-gauge wires and twisted-pair constructions in low-voltage applications.
Solid & foamed insulation
Suitable for solid insulation, or gas-injection foaming with an appropriate nucleant and nitrogen. Process conditions require application-specific qualification.
Films & intricate parts
Industrial film and intricate or thin-wall injection-molded parts that benefit from fluoroplastic properties and high resin flow.

Processing & handling
From pellet
to precision.
Conventional equipment. Application-specific settings. Start with the resin’s processing requirements and qualify your finished product.
Process with proper ventilation.
Use local exhaust ventilation to remove fumes and vapors. Read the current safety data sheet before processing and prevent contamination of smoking tobacco.
Melt processing
FEP 4630 can be processed by melt extrusion and by injection, compression and blow molding. Approximately 3 mm pellets support smooth feeding. Extruders and molding machines should use high-nickel, corrosion-resistant materials and be capable of operating up to 400°C. This is equipment capability, not a universal processing setpoint.
Foamed insulation
Use an appropriate nucleant with nitrogen gas injection. Resin selection, die design and process settings should be validated for your required insulation geometry and electrical performance.
Packaging & storage
Supplied in 25 kg plastic bags. The source recommends 1,000 kg orders for convenient shipment. Store to prevent airborne contamination and condensation when containers are opened.
