PVC compound is a PVC resin that has been mixed with several additives. The purpose of adding this additive is to obtain the quality of the material according to the planned application. Basically PVC resin itself cannot be processed without the addition of additives. Some additives that are often added to PVC resins, for example, plasticizers (make PVC more flexible). Heat stabilizer (makes PVC heat resistant during processing), filler (makes it heavier in density and also cheap). Lubricant (makes the surface / visual smooth and shiny) and several other additives such as flame retardant additive (makes it more resistant to fire), UV resistance (resistant to UV radiation from the sun), anti-fungal, anti-termite and so on.
