Plastic seal technology: how much do you know
- Mar 03, 2017 -

Plastic seals usually made from plastic polymers, also known as polymers, or macromolecules, also commonly known as plastic or resin, you can change the body style. Common construction materials in a wide variety of plastic seal products, usually made of plastic seal is a kind of Engineering Thermoplastics.
Plastic seal the material is polyethylene: commonly used can be divided into low pressure polyethylene, polyethylene and linear polyethylene LDPE. Among the three, HDPE has good thermal properties, electrical properties and mechanical properties of LDPE and LLDPE have better flexibility, impact resistance, film and so on. LDPE and LLDPE are mainly used for packaging film, agricultural film, plastic modification, etc.
Plastic seals are made of polyvinyl chloride PVC for short, by polymerization of vinyl chloride in the presence of initiator made of thermoplastic resin. Is vinyl chloride homopolymer. Vinyl chloride homopolymer and collectively referred to as vinyl chloride vinyl chloride copolymer resins. It has good elasticity and impact resistance, commonly used as a raw material for plastic seal.
Plastic seals of role and making process introduced: seals used PP plastic once injection forming, seals within clip has steel tablets, products in lingxia45du, lingshang50du not variant, surface used stamping or laser playing logo, and water,, and barcode, lock rod for 2*5 flat rod, Shi seal Shi free regulation pull tight, color can made red, and blue, and green, and yellow, also can according to user requirements making into other color,.
