Our High Performance Polyimide Engineering Rod is the premier choice for extreme industrial applications where standard plastics fail. Known for its exceptional wear resistance and ability to withstand continuous high temperatures up to 300°C, this material offers superior dimensional stability with a low molding shrinkage rate and minimal water absorption (0.1%-0.3%).
Featuring a high tensile strength of 95-130 MPa, our PI rod is ideal for precision machining and serves as a direct Vespel SP1 equivalent. It is widely used in aerospace, semiconductor, and automotive industries for seals, bearings, and insulators.
1. Exceptional Thermal Stability
- Description: Capable of continuous use at temperatures up to 260°C (500°F) and short-term exposure to over 400°C.
- Technical Advantage: Maintains high mechanical strength at elevated temperatures and remains non-brittle even at cryogenic temperatures (e.g., -269°C in liquid nitrogen).
2. Ultra-Low Friction Coefficient
- Description: Boasts an extremely low coefficient of friction (approx. 0.08 - 0.25) and possesses self-lubricating properties.
- Technical Advantage: Performs excellently in oil-free or maintenance-free environments, significantly reducing wear on mating metal surfaces.
3. Superior Wear Resistance
- Description: Exhibits excellent wear resistance, especially grades filled with graphite or molybdenum disulfide (MoS2), such as equivalents to Vespel SP21/SP22.
- Technical Advantage: Ideal for manufacturing bearings, seals, and wear-resistant bushings, offering a service life far exceeding that of standard plastics.
4. Excellent Mechanical Strength
- Description: Features high tensile strength (95-130 MPa) and superior creep resistance.
- Technical Advantage: Resists deformation under high pressure and heavy loads, providing excellent dimensional stability suitable for precision machining.
5. Outstanding Chemical Resistance
- Description: Resistant to organic solvents, oils, fuels, and hydraulic fluids.
- Technical Advantage: Maintains stable performance in most chemically corrosive environments (Note: Not resistant to strong alkalis or concentrated sulfuric acid).
6. Good Electrical Insulation
- Description: Offers a low and stable dielectric constant with excellent arc resistance.
- Technical Advantage: Serves as a reliable electrical insulator even under conditions of high temperature, high humidity, or high frequency.
7. Low Water Absorption
- Description: Has an extremely low water absorption rate (0.1% - 0.3%).
- Technical Advantage: Dimensions are minimally affected by humidity, ensuring the precision of critical parts across varying environmental conditions.
