Static charges that build up on the surface of plastic products can attract dust and dirt, cause sheet and film to cling, and cause stacked products to stick together. This static buildup can then cause the resulting parts, film or sheet to cling to one another, or stick to the mold or tool.

THE CHALLENGE PVC sheet and profile extrusion processors were looking for ways to hit lower density targets while maintaining a high-quality cell structure. The result was lower production density with fewer voids in the extruded sheet or profile, leading to higher quality finished goods and a reduction in scrap rates.
