1. Non-toxic, odorless, low density, strength, stiffness, hardness and heat resistance are better than low pressure polyethylene. It can be used at about 100 degrees. It has good electrical properties and high frequency insulation. It is not affected by humidity, but it changes with time at low temperature. Brittle, not wear-resistant, easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common acid and alkali organic solvents have little effect on it and can be used for tableware.

2. Combustion characteristics: It is flammable and continues to burn after leaving the fire. The upper end of the fire is yellow, the lower end is blue, and there is a small amount of black smoke. When burning, it dissolves and drips. And emits petroleum smell. Injection temperature 190-240.

3. PVC It is one of the plastic products with the largest output in the world. It is cheap and widely used. The polyvinyl chloride resin is white or light yellow powder. Different additives can be added according to different uses, and PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products.

4. The density of pure PVC is 1.4g/cm3, and the density of PVC plastic parts with plasticizers and fillers is generally 1.15-2.00g/cm3.
