Plastic seal is a polymer compound synthesized from plastic
Plastic seals are generally polymer compounds synthesized from plastics, which can also be called macromolecules or macromolecules. They are also commonly known as plastics or resins, which can change their shape and style. There are many types of common construction materials for plastic seal products, and the commonly used plastic seal is made of a thermoplastic engineering plastic.
The material used for plastic seals is polyethylene: commonly used polyethylene can be divided into low pressure polyethylene, high pressure polyethylene and linear high pressure polyethylene. Among the three, HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE have better flexibility, impact properties, film-forming properties, etc. LDPE and LLDPE are mainly used for packaging films, agricultural films, and plastic modification.
The plastic seal is made of polyvinyl chloride, abbreviated as PVC, and is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. It has good elasticity and impact resistance, so it is often used as a raw material for plastic seals.
