Quasi MDI-agumisa mamiriro ezvinhu
Quasi MDI-wakagumiswa PTMG maitiro
KUTSANANGURWA
Chinoumba: DY2513 ndiyo umbwa pedyo yenhengo ABC. Chinoumba A ndiye polyol, B ndiye polyurethane prepolymer iyo dzakaguma pamwe isocynate, C ndiye cheni extender.
Mamirire: The yokupedzisira chigadzirwa inahwo zvakanaka zvevanopesana nemishonga mano, zvakanaka rebound. Uye pokuoma zvinogona kugadziridzwa kubudikidza yakasiyana reshiyo. Ruvara zvinogona kugadziridzwa ne ruvara.
Application: Izvi zvinhu rakashandiswa kugadzira Polyurethane sieves, PU rollers, kuchenesa nguruve (discs) uye dzimwe elastomer.
