Plastic Industry

Plastic is a group of synthetic or semi-synthetic materials obtained from the polymerization process. Plastics are typically organic polymers of high molecular mass. Plastic is a synthetic material and is not found nature. Plastics can be made into various shapes under thermal and mechanical process. The tiles used in the plastics industry are fine and somewhat white and contain a small amount of iron. About 2.9% of consumed talc in plastic industry worldwide is used as filler. In the plastic industry talc is used as filler due to its shape, size, thermal resistance and ductility. Also, talc is added to plastic to increase mechanical strength and improve the surface quality (reduce abrasion). In cars, special plastics entitled engineering thermoplastics (ETP) are used
The plate shape of talc particles can increase the hardness of products such as propylene, vinyl, polyethylene, nylon and polyester. It can also increase the thermal resistance of these products and reduce their contraction. Due to the very low hardness of the talc used in plastic making, the plastic will be easily removed from mold and less abrasion will be created on it in compare with other minerals with more hardness. Another use of talc in plastics is for increasing adhesion impact strength.
