1. Overview of PEI Plastic Material
Polyetherimide (PEI) Resin is a transparent or opaque amorphous thermoplastic with a remarkable combination of properties:
High Thermal Resistance: Maintains structural stability at continuous use temperatures up to 170–200°C, and short-term exposure up to 220°C.
Excellent Mechanical Strength: Retains rigidity and dimensional stability under high loads and mechanical stress.
Outstanding Chemical Resistance: Resistant to hydrolysis, solvents, fuels, and various chemicals.
Flame Retardancy: Meets UL94 V-0 standards without additional additives, making it suitable for electrical and electronic applications.
Electrical Insulation: Exceptional dielectric properties suitable for high-temperature electrical components.
PEI is available in virgin grades, reinforced variants, and black masterbatches for tailored performance in color, mechanical properties, and thermal conductivity.
2. Key Features of PEI Material
High-Temperature Resistance: Suitable for applications requiring long-term performance at elevated temperatures.
Dimensional Stability: Minimal warping or shrinkage ensures precise parts in injection molding and machining processes.
Durable and Wear-Resistant: Ideal for components subjected to friction or mechanical stress.
Customizable Color and Formulation: Including High Temperature Black Masterbatch for opaque or reinforced parts.
Chemical and UV Resistance: Maintains performance in challenging industrial and outdoor environments.
Biocompatibility (select grades): Some medical-grade PEI is suitable for sterilizable medical devices.
