Polyimide SP-1 Grade Blocks 50×50 mm — High Temperature Resistant Engineering Plastic
High-Performance Polyimide Blocks for Extreme Applications
The SP-1 grade polyimide block is a high temperature resistant engineering plastic designed for demanding industrial environments. With excellent heat resistance, dimensional stability, and machinability, these blocks are widely used in aerospace, automotive, electronic insulation, and industrial tooling. Each block is supplied in a 50 × 50 mm (≈1.97" × 1.97") footprint with thickness options of 35 mm (1.38"), 40 mm (1.57"), 45 mm (1.77"), and 50 mm (1.97").
✔ Key Benefits of SP-1 Polyimide Blocks
- ✅ Heat resistance: Continuous use up to 260 °C (500 °F), ideal for high-temperature insulation and structural applications.
- ✅ Dimensional stability: Low creep and tight machining tolerances (±0.05 mm typical).
- ✅ Chemical durability: Resistant to fuels, oils, and solvents in industrial environments.
- ✅ Mechanical strength: Excellent wear resistance and long service life.
- ✅ Lightweight: Easier handling and reduced logistics costs compared to metals.
