muovityypin
Muovityypin refers to the classification or type of plastic. Plastics are broadly categorized based on their chemical structure, properties, and manufacturing processes. Common classifications include thermoplastics and thermosets. Thermoplastics can be repeatedly softened by heating and solidified by cooling, allowing them to be molded into various shapes. Examples include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). Thermosets, on the other hand, undergo irreversible chemical changes upon heating and curing, forming a rigid, cross-linked structure that cannot be reshaped by reheating. Examples include epoxy resins, phenolic resins, and vulcanized rubber.
Further subdivisions of plastic types exist based on specific properties, such as density, flexibility, transparency, and
