Description

technical field [0001] The invention relates to the technical field of heater production, in particular to a heater shell material filled with nano barium sulfate and modified PET. Background technique [0002] Functional polymer materials are currently a hot spot in material science research, and polymer composite conductive materials with PET characteristics are among the best. So far, the academic and industrial circles are actively researching and developing it. PET is one of the commonly used disposable plastic materials polyethylene terephthalate plastics, the chemical name is polyethylene terephthalate (PET), commonly known as polyester resin. The molecular structure of PET is highly symmetrical, and it has a certain crystal orientation ability, so it has high film-forming properties. It is often used in the electrical and electronic and automotive industries, various coil skeletons, transformers, TV sets, tape recorder parts and casings, Processing materials for aut...
