Material Properties & Performance
Virgin-grade polytetrafluoroethylene (PTFE) represents the gold standard in high-performance engineering plastics. This material exhibits unparalleled chemical inertness, making it impervious to acids, bases, solvents, and corrosive compounds that would degrade conventional materials.
The molecular structure of PTFE creates an ultra-low surface energy, delivering the lowest coefficient of friction of any known solid material—ideal for bearing surfaces, seals, and sliding applications where minimal wear and smooth operation are critical.
⚗️ Chemical Resistance
Resistant to virtually all industrial chemicals, acids, alkalis, and solvents. Only molten alkali metals and fluorine gas at elevated temperatures affect PTFE.
🔥 Thermal Stability
Maintains mechanical properties from cryogenic temperatures (-200°C) to continuous service at 260°C, with short-term excursions to 300°C.
⚡ Electrical Properties
Outstanding dielectric strength and low dissipation factor across wide frequency ranges. Ideal for high-voltage insulation and RF applications.
💧 Non-Stick Surface
Extremely low surface energy prevents adhesion of most substances. Self-lubricating properties eliminate the need for external lubricants.
🛡️ Weather Resistance
Unaffected by UV radiation, ozone, and atmospheric conditions. Suitable for outdoor applications with no degradation over time.
🔬 FDA Compliance
Virgin-grade PTFE meets FDA 21 CFR 177.1550 for food contact applications and USP Class VI biocompatibility standards.

Fabrication & Machining Guidelines
Cutting & Sawing
Use carbide-tipped tools at moderate speeds. Band saws, circular saws, and guillotines all work effectively. Keep tools sharp to prevent material deformation.
Drilling & Punching
Standard HSS or carbide drills perform well. Use backing plates to prevent material distortion. Punch tooling should be sharp with minimal clearance.
Turning & Milling
CNC machining achieves excellent results. Use positive rake angles and adequate support to minimize deflection. Coolant is generally not required.
Bonding & Joining
PTFE's low surface energy requires surface treatment (sodium etching or plasma) before adhesive bonding. Mechanical fastening is often preferred.
