Universal Processing

Robust Melt Strength & Extrusion Control

MFI 6.0–12.0 g/10min Processing Versatility: Tailored with a balanced molecular weight profile, FEP 4610 provides high melt strength and draw-down stability, making it the ideal general-purpose resin for standard-wall wire insulation, heavy-duty tubing, and compression molding.

Heavy-Duty Durability

Maximum Stress-Crack & Abrasion Resistance

Industrial-Grade Mechanical Armor: Exhibits superior tensile strength (24 MPa) and extraordinary environmental stress-crack resistance (ESCR). Built to withstand high mechanical pull, tight bundling, and abrasive wear in industrial environments.

Dielectric Reliability

Stable High-Voltage & RF Barrier

Low Permittivity (2.03 @ 1 GHz): Delivers rock-solid insulation for high-voltage industrial lead wires, aerospace wiring, and instrumentation lines with dielectric strength exceeding >100 kV/mm across extreme temperature cycles.

Extreme Defense

UL 94 V-0 Safety & Total Chemical Immunity

Zero Flammability Risk (LOI > 95%): Features self-extinguishing safety with minimal smoke generation. Defies aggressive petrochemicals, battery acids, hydraulic fluids, and corrosive vapors at operating temperatures up to 205 °C (400 °F).

Target Applications

Engineered for heavy-duty industrial wiring & chemical fluid systems.

APPLICATION 01

Industrial & Aerospace Wire Harnesses

Premium insulation for military aircraft airframe wiring, oil & gas downhole sensor cables, automotive engine compartment harnesses, and industrial equipment requiring rugged cut-through resistance.

APPLICATION 02

Corrosive Fluid Tubing & Gas Sampling Lines

Extrudes heavy-wall and medium-wall fluoropolymer tubing, heat exchanger coils, and continuous environmental gas sampling tubes requiring crack resistance and total chemical impermeability.

APPLICATION 03

Molded Chemical Liners & Heavy Fittings

Provides outstanding melt integrity for compression-molded anti-corrosion valve linings, pump diaphragms, flanged pipe fittings, and electrical feedthrough seals.
