Plastic seal process how much you know it

Plastic seals are generally made ​​of plastic for the synthesis of polymers, also called polymer or giant molecule , is also generally known as plastic or resin , can change the body style. Plastic seal products wide range of common construction materials commonly used accory plastic truck seals is a thermoplastic engineering plastics .Plastic seal material is used in polyethylene: common polyethylene can be divided into low-pressure polyethylene , high-pressure polyethylene and linear LDPE . Among the three , HDPE has a better thermal properties, electrical properties and mechanical properties of LDPE and LLDPE which has a good flexibility, impact resistance , film formability and the like. LDPE and LLDPE is mainly used for packaging film , agricultural film, plastic modification .Use PVC referred to as PVC accory adjustable length plastic seals made ​​of thermoplastic resin made ​​by the polymerization of vinyl chloride in the role of initiator . Is a vinyl chloride homopolymer. Homopolymers of vinyl chloride and vinyl chloride copolymer resin collectively . It has good flexibility and impact resistance, so often used as a raw material of plastic seals .The role of the plastic seal and production process description : Seal with PP plastic injection molding , there are the steel inner seal products at minus 45 degrees , 50 degrees above zero the same type , the surface stamping or laser mark , serial number , bar code, locking lever is 2 * 5 flat lever , adjustable tighter seal when applied , the color can be made of red, blue , green, yellow , can also be made ​​into other colors according to user requirements .Plastic seal is made ​​of engineering thermoplastics Plastic seals are generally made ​​of plastic for the synthesis of polymers, also called polymer or giant molecule , is also generally known as plastic or resin , can change the body style. Plastic seal products wide range of common construction materials commonly used plastic seal is a thermoplastic engineering plastics .
