PVC has excellent flame retardancy, wear resistance, chemical corrosion resistance, comprehensive mechanical properties, product transparency, electrical insulation, and relatively easy processing characteristics. So, what are the characteristics of PVC plastic extrusion molding? Let's take a look below.

PVC is a non crystalline material with flame retardancy, good chemical stability and low tensile force. It has excellent flame retardancy, wear resistance, chemical corrosion resistance, comprehensive mechanical properties, product transparency, electrical insulation, and relatively easy processing characteristics, and has been widely applied in various fields. So what are the characteristics of PVC plastic profile extrusion molding? Let's take a look below.

Characteristics of PVC plastic profile extrusion molding:

1. Amorphous material, low moisture absorption, and poor fluidity. In order to improve fluidity and avoid bubbles, the plastic can be pre dried. The mold pouring system should be thick and short, the gate section should be large, and there should be no dead corners. The mold must be cooled and the surface should be chrome plated.

2. It is easy to differentiate, and it is easier to differentiate when touched with steel or copper at a temperature of 200 degrees. During differentiation, corrosive and irritating gases escape, and the forming temperature scale is small.

When selecting a screw type injection machine nozzle, the aperture should be large to prevent dead corners and material stagnation, without any inserts. If there are inserts, they should be preheated.

PVC is a good building material, which mainly has the functions of preventing mold and moisture, and has the effect of not absorbing water. It can be sawn off or drilled off, and it mainly has the effect of bending. It is widely used in bathrooms, cabinets, and furniture. The above are the extrusion molding characteristics of PVC plastic profiles, hoping to be helpful to everyone.
