kovamuovi
Kovamuovi is Finnish for rigid plastic material used in the production of sheets, panels and molded parts. The term denotes hard, dimensionally stable plastics as opposed to flexible polymers such as elastomers or soft plastics. Kovamuovi encompasses several polymers manufactured in rigid form, including PVC (rigid vinyl), PMMA (acrylic), PC (polycarbonate), PS (polystyrene) and PETG, as well as blends and reinforced variants.
Rigid plastics used in kovamuovi offer high stiffness, good dimensional stability and a wide temperature range,
Manufacturing methods for kovamuovi include extrusion or calendering for sheet stock, and injection molding or thermoforming
