muoviraakaaineiden
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),
These raw materials are usually supplied in the form of small pellets or granules. Manufacturers then melt
