I-MDI Porfecymer
Ubulukhuni: Usogwini A 75a - Ugu lwe-95a
Umkhiqizo unezici zokumelana okuhle kokugqokwa, ukuqina kanye nezakhiwo ezinhle kakhulu zemishini.
Isetshenziselwa ukwenza imikhiqizo emihle ye-polyurethane elastomer efana namasondo enjoloba, amapuleti abuhle nezindandatho zokubopha uphawu.
