Our custom PTFE gaskets are made from 100% virgin polytetrafluoroethylene (PTFE), known for its outstanding chemical resistance, wide temperature tolerance, and ultra-clean sealing capability. These PTFE sealing gaskets are ideal for static sealing in flange connections, valves, pumps, и reactor vessels, particularly in environments requiring extreme corrosion resistance and purity, such as химическая обработка, pharmaceutical manufacturing, food-grade systems, и semiconductor cleanrooms.
Exceptional chemical resistance: Withstands over 98% of aggressive acids, bases, and organic solvents including hydrofluoric acid and sulfuric acid.
Wide temperature performance: Operates reliably from от -200°C до +260°C, with short-term peaks up to 300°C.
FDA/EU food-grade compliant: Suitable for CIP systems, biopharmaceutical pipes, и sterilization lines.
Ultra-low friction: Permanent self-lubricating surface with a coefficient of friction ~0.05.
High dimensional stability: Supports ±0.1mm precision customization with multiple thicknesses available (0.5mm–10mm).
Excellent dielectric performance: Perfect for electrical insulation applications.
Non-contaminating: Made from pure resin with no fillers, suitable for ultra-high-purity использовать.
Chemical Equipment: Flange gaskets and static seals for acid/alkali pipelines, reactors, valves
Food Industry: FDA-compliant PTFE gaskets for sanitary pipe systems, mixing tanks, и filling machines
Pharmaceutical & Medical: Clean seals for GMP-compliant bioprocessing, sterilizers, and freeze dryers
Semiconductor Manufacturing: PTFE insulation gaskets for wafer carriers, ultra-pure gas systems
Green Energy / Hydrogen Electrolysis: Long-life PTFE sealing rings для alkaline medium sealing
Custom Machinery: Ideal for replacing worn-out metal gaskets in legacy or narrow joint assemblies
Customization flexibility: Any shape, thickness, diameter
High sealing integrity under low torque or irregular flange faces
Reduced maintenance downtime with longer gasket lifespan
Cleanroom compatible and non-leaching properties
