What is the material of the disposable raincoat
Disposable raincoats can be made of polyvinyl chloride plastic (pvc) or polyamide plastic (pa).
Polyvinyl chloride plastic (pvc): Polyvinyl chloride plastic is made by polymerizing vinyl chloride monomer and is one of the commonly used thermoplastics. Its product name is abbreviated as “Chlorine Plastic” and the English abbreviation is PVC. Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature is very close to the plasticizing temperature, and its mechanical strength is poor. Therefore, it is impossible to use polyvinyl chloride resin to plastic products, and plasticizers, stabilizers, fillers, etc. must be added to improve performance to make polyvinyl chloride plastics, which are then processed into various products. Polyvinyl chloride is divided into rigid polyvinyl chloride and soft polyvinyl chloride according to the amount of plasticizer added.
Polyamide plastic (pa): PA plastic is the first resin developed by a company in the United States for fiber, and it was industrialized in 1939. In the 1950s, it began to develop and produce injection molded products to replace metal to meet the requirements of downstream industrial products to reduce weight and reduce costs. PA has good comprehensive properties, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and has low friction coefficient, certain flame retardancy, easy processing, suitable for glass fiber and Other fillers are filled to enhance modification, improve performance and expand the scope of application.
