Pei Sheet: High Performance Engineering Plastic

Product Description

Product Description
PEI (Polyetherimide) is a high-performance engineering plastic renowned for exceptional heat resistance, mechanical strength, and chemical stability. It maintains structural integrity at continuous use temperatures up to 170°C, with low water absorption (≈0.5% at 50% RH) ensuring dimensional stability. Flame-retardant and inherently tough, PEI offers excellent electrical insulation and processability via injection molding or extrusion. Ideal for aerospace, automotive, electronics, and medical applications requiring reliability in harsh environments.
Product Features
1. High Temperature Resistance: Continuous service temperature up to 170°C, short-term resistance above 200°C, with excellent thermal aging resistance.
2. High Mechanical Strength: Tensile strength of unreinforced grade is approximately 165MPa, featuring good rigidity, impact resistance, and minimal deformation during long-term use.
3. Strong Stability: Low water absorption (≈0.5% at 50% RH) ensures dimensional stability; resistant to most chemical media (except strong acids and alkalis) and achieves UL94 V-0 flame retardancy rating.
4. Excellent Insulation: Maintains good electrical performance even at high frequencies, suitable for the electronics and electrical industry.
5. Easy Processability: Can be formed via processes such as injection molding and extrusion, suitable for the production of precision components.
