Core Technological Advantages

Engineered for Flawless Paste Extrusion.

Everflon™ PTFE F500 combines superior molecular integrity with predictable batch-to-batch flow dynamics.

Thermal Stability

Cryogenic to 500°F (260°C)

Retains structural toughness and high ultimate elongation from –400°F (–240°C) up to 500°F (260°C). Withstands extreme thermal cycles in high-heat automotive engine compartments and aerospace assemblies.

Processing Efficiency

High Reduction Ratio (100:1–600:1)

Engineered for smooth ram extrusion with low preform pressure (1.5–2.0 MPa) and moderate extrusion resistance (23 MPa at RR 400:1), guaranteeing uniform wall thickness and concentricity.

Chemical Shield

Universal Chemical Inertness

Complete inertness to virtually all aggressive industrial acids, alkalis, hydraulic fluids, hydrocarbon fuels, and reactive process gases with negligible moisture absorption.

Fatigue Resistance

Superior Stress Crack Resistance

Exceptional flex life, ultra-low stretch void index (SVI < 50), and high clarity make F500 suitable for demanding post-forming including flanging, welding, and convoluting.

Electrical Quality

High-Frequency Dielectric Stability

Exceptional dielectric properties invariant across vast frequency ranges and elevated temperatures, providing high-integrity insulation for micro-miniature wiring and coaxial cable sleeving.

Regulatory Safety

FDA & European Certified

Fully compliant with FDA 21 CFR 177.1550 and European Union Regulation (EU) No. 10/2011 for direct food contact and sanitary pharmaceutical liquid transfer lines.

Industry Deployment

Designed for Mission-Critical Fluid Transfer.

Meeting stringent burst pressure, cyclic pulsation, and permeation standards across American manufacturing sectors.

Automotive & Aerospace Hoses

Overbraided hydraulic lines, aircraft fuel assemblies, turbocharger oil feeds, and high-performance automotive brake systems operating under cyclic pressure.

Chemical & Pharma Tubing

Smooth-bore and convoluted tubing handling aggressive solvents, reactive chemicals, and ultra-clean pharmaceutical bioprocess transfers with zero contamination.

Spaghetti Tubing & Wire Wrap

Thin-wall spaghetti tubing and high-frequency wire jackets demanding high breakdown voltage, precise wall concentricity, and extreme thermal resilience.

Secondary Fabrication Lines

Engineered with superior flexural recovery for precision secondary operations including thermal flanging, bell-mouthing, butt welding, and blow molding.

Engineering Protocol

Optimized Paste Extrusion Workflow.

Step-by-step engineering parameters to guarantee continuous zero-defect extrusion lines.

Stage 01

Compounding & Preform

Blend uniformly with dearomatized hydrocarbon lubricants. Preform at controlled light pressure (1.5–2.0 MPa / 220–290 psi) to eliminate trapped micro-voids.

Stage 02

Ram Paste Extrusion

Extrude at reduction ratios between 100:1 and 600:1 through precision dies. The green structure develops high fibrous cohesion and concentric wall thickness.

Stage 03

Thermal Sintering

Evaporate lubricants in an inline oven at 100–300°C (212–572°F). Sinter above 342°C (648°F) to melt into a completely fused, void-free fluoroplastic resin.

Critical Storage

Sub-19°C (66°F) Handling

Fine powder is sensitive to shear-induced fibrillation. Store below 19°C (66°F), avoid excessive mechanical vibration, and gently screen through 4–10 mesh sieves before preforming.
