Sebenzisa
Le mveliso ibonelela ngokhuseleko lwe-ultraviolet kwiintlobo ngeentlobo zeepolymers kuquka ii-homo- kunye nee-copolymers ze-styrene, iiplastiki zobunjineli ezifana nee-polyesters kunye nee-acrylic resins, i-polyvinyl chloride, kunye nezinye ii-halogen eziqulathe iipolymers kunye nee-copolymers (umz. ii-vinylidenes), ii-acetals kunye nee-cellulose esters. Ii-Elastomers, ii-adhesives, ii-polycarbonate blends, ii-polyurethanes, kunye nezinye ii-cellulose esters kunye nezinto ze-epoxy.
