The Pure PTFE Rod is a premium-grade engineering plastic made from 100% virgin Polytetrafluoroethylene (PTFE). Known for its outstanding chemical resistance, ultra-low friction coefficient, superior dielectric strength, and wide temperature stability, this material is ideal for demanding industrial applications.
Certified to FDA and USP Class VI standards, the pure PTFE rod ensures safety, purity, and reliability for use in food processing, pharmaceuticals, and medical device manufacturing. It remains stable and non-reactive even under extreme environmental or chemical conditions, outperforming most conventional materials.
Exceptional Chemical Resistance
Withstands nearly all acids, alkalis, oxidizers, and solvents—making it a superior choice over metal and other plastics in corrosive environments.
Extreme Temperature Stability
Maintains mechanical integrity from -200°C to +260°C without cracking, melting, or degrading, suitable for both cryogenic and high-temperature systems.
Lowest Friction Coefficient
Among all solid materials, PTFE has the lowest friction coefficient, ensuring self-lubrication, non-stick performance, and minimal wear under motion.
Superior Electrical Insulation
Provides high dielectric strength and stable insulation even in high-frequency and humid conditions, ideal for electronic and communication components.
FDA/USP Certified Purity
Made from 100% virgin PTFE, non-toxic and odorless, meeting strict food-grade and pharmaceutical-grade requirements for safety and compliance.
Excellent Weather and Aging Resistance
Unaffected by UV radiation, ozone, and harsh outdoor conditions, ensuring long service life with minimal degradation.
1. Chemical & Process Industries
Used for seals, gaskets, valve seats, bearings, expansion joints, and pipeline linings, providing high corrosion resistance.
2. Food & Pharmaceutical Equipment
Ideal for food-contact fixtures, pharmaceutical seals, molds, and bearing supports, ensuring hygiene and compliance.
3. Electrical & Electronics
Applied in insulation bushings, high-frequency components, coil supports, and connectors.
4. Mechanical & Automation Systems
Used in low-load bearings, guide rings, sliders, and lubrication-free components to minimize friction and wear.
5. Semiconductor Manufacturing
Applied in wafer carriers, vacuum fittings, and corrosive gas systems, offering high purity and chemical resistance.
Material: 100% virgin PTFE, no recycled or filled material
Standards: Meets ASTM, ISO, FDA, and USP Class VI requirements
Machinability: Excellent; suitable for turning, milling, and shaping complex parts
