Chunhuan’s CNC-machined PTFE screws and bolts are precision-engineered for demanding applications where metal fasteners fail due to corrosion, contamination, or insulation issues.
Исключительная химическая стойкость
Resists acids, alkalis, solvents, oxidizers — ideal for chemical processing, plating, and pharmaceutical equipment.
Extreme Thermal Tolerance
Operational range from от -200°C до +260°C, with short-term resistance up to 300°C — suitable for cryogenic and steam environments.
Non-Stick & Self-Lubricating
Friction coefficient as low as 0.04, perfect for applications like extrusion dies, hot glue systems, and anti-fouling assemblies.
High Electrical Insulation
Dielectric strength up to 10 кВ/мм and volume resistivity >10¹⁸ Ω·cm — safe for high-voltage terminals, electrolytic systems, and clean electrical connections.
FDA & Pharmaceutical Compliance
Pure PTFE screws meet FDA 21 CFR 177.1550 and USP Class VI, ensuring safety in food, cleanroom, and biopharma settings.
Flange sealing, reactor sight glass mounting
Semiconductor wafer handling & cleanrooms
Pharmaceutical filling systems
Electroplating racks & acid-resistant fixtures
Electrical terminals & cable insulation fasteners
Pure PTFE – For high-purity, clean environments
Наполненный ПТФЭ – Reinforced with glass fiber, carbon fiber, or graphite for added mechanical strength and wear resistance
✅ Why Choose PTFE Screws Over Metal?
Unlike metal fasteners that corrode or contaminate sensitive systems, PTFE screws provide unmatched chemical inertness, zero ion leaching, and long-term reliability under harsh conditions.
