1. Mechanical Strength: With the addition of 30% glass fiber, PEI GF30 exhibits a significant improvement in rigidity and mechanical strength. The tensile and flexural strengths of the glass fiber-reinforced PEI profile PEIGF30 are approximately 1.4 times that of pure PEI. This enhancement enables PEIGF30 to withstand higher static loads and dynamic stresses, making it suitable for applications requiring high strength and rigidity.
2. Temperature Resistance: In high-temperature environments, PEI GF30 maintains its shape and dimensional stability, showing little deformation or size change. While pure PEI has a thermal deformation temperature of 201°C, PEI GF30 has a thermal deformation temperature of 210°C, providing enhanced thermal stability.
3. Dimensional Stability: PEI GF30 performs exceptionally well in applications requiring resistance to friction and temperature variations. Its coefficient of thermal expansion is half that of PEI Natural, resulting in better wear resistance and a smaller thermal expansion coefficient.
4. Application Range: PEI GF30 is widely used in environments that require resistance to high stresses, fatigue stresses, or impact stresses, such as automotive parts (interior and exterior), semiconductor processing, precision bearings, mechanical load-bearing components, wind power equipment, new energy battery components, and electrical systems. PEI GF30 offers greater advantages in applications demanding higher strength and stability.
5. Processing Characteristics: Although PEI GF30 may be slightly more challenging to process than pure PEI, efficient and precise machining can still be achieved by selecting appropriate processing methods and parameters. Furthermore, the reinforcement effect of PEI GF30 results in products with enhanced performance after processing.
