PET 70 may refer to a type of PET material containing 70% specific components (such as glass fiber reinforcement ratio, brightening agent content, etc.), or it may refer to 70 series products. Taking the common 70% glass fiber reinforced PET as an example, it has excellent mechanical properties, high tensile and flexural strength, good rigidity, and can withstand significant external forces, making it suitable for manufacturing automotive engine parts and mechanical structural components. Its heat distortion temperature is significantly improved, allowing it to work stably in high-temperature environments, and it is used in the electronics and electrical appliance fields to make high-temperature resistant sockets, switch housings, etc. Simultaneously, it has good dimensional stability, is less affected by temperature and humidity, and can ensure that products do not deform over long-term use, meeting the manufacturing needs of high-precision parts. Furthermore, it has good chemical corrosion resistance, resisting the erosion of various chemical substances, and has a wide range of applications.
