PVC has high hardness and mechanical properties

PVC has high hardness and mechanical properties

The use of PVC sheet can not only achieve the purpose of increasing production and efficiency, but also has the characteristics of improving land utilization, saving costs, and giving full play to mechanical efficiency.

First, what are the four major properties of PVC sheet:

(1) Mechanical properties:

PVC has high hardness and mechanical properties, which can be increased with the increase of molecular weight and decreased with the increase of temperature. The mechanical properties of hard PVC are much better than those of soft PVC.

(2) Thermal properties:

PVC has poor heat resistance and stability, and begins to decompose at 140 ° C, and its melting temperature is 160 ° C. The linear expansion coefficient of PVC is small, and it has inflammability.

(3) Electrical properties:

PVC is a polymer with good electrical properties, and because of its larger polarity, its electrical insulation is not as good as PP board and PE board.

(4) Environmental performance:

PVC can resist acid, alkali, salt and other organic solvents, more suitable for medicine, chemical anti-corrosion materials.

Second, PVC sheet waterproof coil is a kind of plate commonly used in people's lives, PVC sheet plastic sheet production line with plastic as the main raw material for the production of plastic sheet production line equipment, its raw materials include pvc, PP, PE, PC and so on.
