When we produce PVC products, we produce them through extrusion and injection processes. At this time, various products such as PVC Resin, plasticizer, stabilizer, impact enhancer, calcium carbonate, and pigment are mixed and put into the extrusion and injection machine to mix the products. Leochem's PVC compound division is that supplies the compounds in ONE-PACK to make products of uniform quality that are easy to work with.
