How are plastic seals produced PVC plastic sealing strips are very common among the sealing strips. Generally, plastic sealing strips can be divided into two parts for extrusion production during production. One part is to produce raw materials into the plastic particles we need according to the quality of the product. The second part is to extrude the product through plastic pellets. S
Precautions for plastic seals Now the function is getting worse and worse. The aging mechanism is not the opposite.
