XIFLON PFA TUBE is a semi-finished product manufactured from high-performance perfluoroalkoxy (PFA) resin, sourced from carefully selected and trusted suppliers including XIFLON fluoropolymer resin. Designed for demanding applications, our PFA tubes combine:
Withstand aggressive chemicals, solvents, and prolonged UV exposure.
Continuous service temperature: −90 °C to +260 °C without degradation.
Superior insulation with high dielectric strength and low dissipation factor.
Excellent tensile strength, smooth finish, and a durable non-stick surface.
Our PFA TUBES are manufactured using precision extrusion technology. Prime-grade PFA resin is melted and formed into tubes under tightly controlled temperature and pressure, ensuring consistent dimensions, smooth surfaces, and repeatable performance.
Tight OD/ID tolerances with consistent wall thickness for stable flow and easy assembly.
Ultra-smooth, defect-free inner surface; free of inclusions or metal particles.
No polymer degradation during forming; retains chemical and thermal resistance.
Each batch is tested to ASTM methods to ensure reproducibility and reliability.
