PVC Large Anatomy

PVC Durable Hoarding PVC material is polyvinyl chloride. It is one of the most produced plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder. It cannot be used alone and must be modified.PVC Durable Hoarding PVC is a white powder with an amorphous structure, a small degree of branching, and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastic can exhibit different physical and mechanical properties. By adding an appropriate amount of plasticizer to PVC resin, a variety of hard, soft and transparent products can be made. PVC, the main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is loved, popular and widely used in the world today. PVC Durable Hoarding global usage ranks second among various synthetic materials. PVC is being produced and applied worldwide at a growth rate of 4%. The growth rate of PVC in Southeast Asia is particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. Specific gravity: 1.38 g/cubic centimeter, molding shrinkage: 0.6-1.5%, molding temperature: 160-190°C, melting point 212°C.

Features: Beautiful And Practical Hoardings Excellent mechanical properties, electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. Beautiful And Practical Hoardings Suitable for making thin plates, wire and cable insulation layers, seals, etc.

Molding characteristics:
1.Garden Heat-resistant Hoarding Amorphous material, with low moisture absorption and poor fluidity. In order to improve fluidity and prevent bubbles, the plastic can be dried in advance. The mold pouring system should be thick and short, the gate cross-section should be large, and there should be no dead corners. The mold must be cooled and the surface should be chromium-plated.
2. Garden Heat-resistant Hoarding Due to its corrosive and fluidity characteristics, it is best to use special equipment and molds. All products must add different types and quantities of additives as needed.
3. Garden Heat-resistant Hoarding is extremely easy to decompose. It is more likely to decompose when in contact with steel and copper at a temperature of 200 degrees. During decomposition, corrosive and irritating gases escape. The molding temperature range is small.
4. When using a screw injection machine nozzle, the hole diameter should be large to prevent material stagnation in dead corners. It is best not to have inserts. If there are inserts, they should be preheated.
