Muoviraakaaineet, also known as plastic raw materials or plastic resins, are the fundamental building blocks from which all plastic products are manufactured. These materials are typically derived from petrochemicals, meaning they originate from crude oil and natural gas. The refining process separates these hydrocarbons into various components, which are then polymerized through chemical reactions to create long chains of molecules that form the plastic resin.

The most common types of plastic raw materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and polyethylene terephthalate (PET). Each of these possesses unique properties that make them suitable for different applications. For instance, polyethylene is known for its flexibility and durability, making it ideal for packaging films and bottles. Polypropylene offers good heat resistance and strength, commonly used in automotive parts and textiles. PVC is valued for its versatility and resistance to chemicals and fire, finding use in pipes, window frames, and flooring. Polystyrene is lightweight and insulating, used in disposable cutlery, containers, and insulation. PET is strong and clear, making it a popular choice for beverage bottles and food packaging.

These raw materials are usually supplied in the form of small pellets or granules. Manufacturers then melt these pellets and mold them into desired shapes using various processes such as injection molding, extrusion, and blow molding. The properties of the final plastic product are determined by the type of raw material used, as well as any additives incorporated during the manufacturing process to enhance characteristics like color, strength, or UV resistance.
