Introduction
Most pure polymers have low mechanical properties and wear resistance. Which is sometimes not suitable for some engineering applications. Therefore, it is very necessary to improve these properties by mixing different types of additives. To improve the properties to be higher and more suitable for application. In addition, additives are also added to improve forming properties. Polymers that have been mixed with additives to improve their forming properties are generally called (polymer compounds). Additives used in the mixture to improve the properties of polymers include fillers. Coupling Agents, Impact Modifiers, Nucleating Agents, Plasticizers
