Core Engineering Capabilities

Built for Speed, Thin Walls, and High Integrity.

Everflon™ PTFE F1000 achieves rapid thermal coalescence with low void generation under extreme draw-down conditions.

Extreme Draw Down

High Reduction Ratios up to 2000:1

Engineered for high-speed ram extrusion across demanding reduction ratio ranges (250:1 to 2000:1), minimizing extrusion defects during ultra-thin-wall continuous runs.

Thermal Kinetics

Fast Continuous Sintering Rates

Optimized polymer morphology facilitates efficient lubricant flash-off (100–300°C) and fast gel-phase fusing at >342°C, significantly accelerating line production speeds.

Dielectric Quality

Superior High-Frequency Insulation

Maintains exceptionally low dielectric constant and dissipation factors across wide thermal and radio-frequency bands, critical for aerospace and subminiature signal conduits.

Chemical Shield

Universal Media Resistance

Completely inert to aggressive industrial acids, alkalis, corrosive solvents, and aviation fuel blends with near-zero moisture absorption over long-term deployment.

Thermal Scope

-240°C to +260°C Operating Range

Retains useful mechanical flexibility and high elongation from cryogenic limits (-400°F) up to elevated continuous operating temperatures (500°F).

Purity & Safety

FDA 21 CFR 177.1550 Compliant

Properly sintered end-products qualify for food-contact compliance under FDA 21 CFR 177.1550 and European Regulation (EU) No. 10/2011 standards.

Industry Deployment

Targeted for High-Draw Down Applications.

Engineered specifically for extrusion operations where concentric wall integrity and rapid line speeds are paramount.

Spaghetti & Thin-Wall Tubing

High-precision micro-bore tubing for medical fluidics, analytical sensors, and chemical dispensing requiring pinhole-free structures.

Wire Coating & Cable Jacketing

High-speed continuous primary insulation and outer jacketing for mil-spec aircraft wiring, automotive sensors, and high-frequency data cables.

Corrosive Fluid Conduit

Smooth-bore inner liners for semiconductor chemical delivery, preventing reactive gas and liquid hydrocarbon permeation.

Extruded Beading & Profiles

Solid profile beading and sealing cords requiring exceptional surface smoothness, uniform fibrillation, and low friction.

Standard Paste Extrusion & Sintering Protocol

Compounded with dearomatized liquid lubricant aids (e.g., naphtha/ISOPAR) and preformed at 1.5–2.0 MPa (220–290 psi) into a cylindrical slug. Ram extruded through high-reduction dies to establish green strength, followed by a calibrated two-step thermal cycle:

Phase 1: Lubricant Flash-Off

100°C – 300°C (212–572°F)

Complete volatilization without void creation

Phase 2: Gel-State Sintering

> 342°C (648°F)

Melt coalescence into void-free solid PTFE

Material Integrity Advisory

Sub-19°C (66°F) Storage & Shear Protection

PTFE fine powders are sensitive to irreversible shear-induced fibrillation prior to extrusion. Fibrillated particles appear as surface blemishes or pinhole defects in finished extrusions.

Store resin containers below 19°C (66°F) to minimize mechanical compaction sensitivity.
Screen compacted resin gently through a 2 to 4.76 mm sieve (4 to 10 mesh) prior to compounding.
Maintain cleanroom ambient dew point control to prevent moisture condensation during billet preforming.
