Problems solved by technology

[0004] However, compared with ordinary PC materials, PET has poor heat resistance and low heat distortion temperature. The introduction of PBT materials will inevitably lead to a decrease in heat resistance and flame retardancy of the material, which limits its application. At present, the main The heat resistance is improved by adding heat-resistant additives such as maleimide copolymer and N-phenylmaleimide to the blend system, but it often requires a large amount of addition to play a role, and often lead to deterioration of other properties of the material
