Vespel parts is a real all-rounder. Whether you need it as a seal, a structural part, for thermal insulation, or in a high-friction application—this material has you covered. It's a type of polyimide (PI), which means its molecular chain has a special "imide ring" backbone. Picture a ladder-like structure made of benzene rings and nitrogen-containing rings, which makes it incredibly stable. It also handles heat like a champ, working perfectly fine for the long haul even above 300°C. On top of that, it keeps its electrical insulation and mechanical strength really well.
Buy high-precision Vespel PI CNC parts from Ideal Plastic, China's specialized specialty engineering plastics developer and manufacturer. Utilizing standard Vespel SP-1, SP-21, SP-22, SP-3, and SP-211 polyimide profiles, we deliver custom-machined industrial components engineered for extreme thermal environments. By matching hot-press molding blanks with precision multi-axis CNC finishing, we minimize expensive material waste while ensuring a certified ±0.02mm tolerance for mission-critical applications.
Buy Vespel SP-211 Plates from Ideal Plastic to eliminate mechanical stick-slip. Our specialized high-temperature thermoset plates resolve the thermal softening issues common in traditional melting polymers. Formulated by blending a non-melting polyimide base with 15% graphite and 10% PTFE lubrication fillers, these black structural shapes provide excellent friction control and high wear resistance for heavy-load, unlubricated sliding interfaces.
The Vespel SP-22 Plates manufactured by Ideal Plastic factory are high-performance 40% graphite-filled polyimide (PI) plates, featuring ultra-low thermal expansion, low friction coefficient and excellent dimensional stability close to aluminum and steel standards. Capable of extreme temperature resistance from -260°C to 330°C, outstanding chemical corrosion resistance and radiation resistance, these black PI plates are ideal for high-temperature, high-friction and high-precision industrial scenarios.

Vespel SP-21 Plates from Ideal Plastic factory are high-performance black polyimide (PI) composite sheets modified with 15% graphite filler. Different from high-graphite SP-22 grades, SP-21 balances ultra-high mechanical strength, stable electrical performance and excellent self-lubricating wear resistance while retaining full extreme temperature resistance of pure PI materials.
1. ultra-low water absorption
2. micrometer-level dimensional stability
3. outstanding creep resistance
4. chemical corrosion resistance
5. for long-term stress-bearing, high-precision and anti-wear industrial scenarios.
Ideal Plastic factory's Vespel SP-3 Plates are 15% molybdenum disulfide filled polyimide sheets for vacuum and inert gas extreme environments. Surpassing graphite-based SP-21/SP-22, it delivers extreme temperature resistance (-269°C to 400°C), reliable self-lubrication, flame retardancy and radiation resistance. Contact us!
