Tok i go pas long EVA Hot Melt Adhesive

EVA hot melt adhesive em i wanpela solvent-fri, wara-fri, 100% strongpela, 'fusible polymer'. Em i strong long rum tempereja na i save melt i kamap olsem wanpela 'flowable', 'viscous liquid adhesive' taim ol i hatim i go inap long wanpela mak. Bihain long em i melt, em i kamap wanpela lait braun, translusen o waitpela samting. Bikpela samting bilong 'hot melt adhesive', em 'basic resin', em i wanpela 'copolimer' bilong 'ethylene' na 'vinyl acetate' aninit long bikpela presa, na ol i bungim wantaim ol 'tackifiers', 'viscosity modifiers', 'antioxidants', na ol narapela samting, long kamapim 'hot melt adhesive'.

EVA em i wanpela plastik samting we i gat ethylene (E) na vinyl acetate (VA) long en. Ol i ken stretim 'ratio' bilong dispela tupela kemikal long inapim ol narapela narapela nid bilong yusim. Sapos i gat planti 'vinyl acetate' (VA) insait long en, dispela i save mekim 'transparency', 'softness', na 'toughness' i kamap gutpela moa.

Ethylene-vinyl acetate copolymer (ol i save kolim tu olsem ethylene-vinyl acetate copolymer) em ol i kisim long rot bilong kopolimerisim ethylene (E) na vinyl acetate (VA). Nem bilong en long tok Inglis em Ethylene Viny Acetate, sotpela nem bilong en olsem EVA o E/VAC. Ol rot bilong mekim polimeraisesen i gat hai-presa bikpela polimeraisesen (bilong ol plastik), solusen polimeraisesen (PVC prosesing aids), emulsen polimeraisesen (ol glu), na saspensen polimeraisesen. Ol i save yusim 'emulsion polymerization' long 'vinyl acetate' (VA) konten we i antap long 30%, tasol ol i save yusim 'high-pressure bulk polymerization' long liklik VA konten. EVA i gat planti kain wok.

Planti taim, EVA we i gat 'vinyl acetate' aninit long 5% em ol i save yusim long wokim ol piksa, LDPE modifaia bilong ol waia na kebol, na ol glu; EVA wantaim 5%-10% bilong 'vinyl acetate' em ol i save yusim long wokim ol 'elastic film'; EVA wantaim 20%-28% bilong 'vinyl acetate' em ol i save yusim long wokim ol 'hot melt adhesives' na ol samting bilong 'coating'; na EVA wantaim 5%-45% bilong 'vinyl acetate' em ol i save yusim long wokim ol piksa (olsem ol piksa bilong egrikalsa) na ol pepa, ol samting we ol i wokim long injeksen na ol samting we ol i wokim long 'mould', ol samting we i gat 'foam', na ol 'hot melt adhesives'. Ol i save yusim planti taim long ol samting bilong su we i gat 'foam', ol 'functional greenhouse films', ol 'packaging molds', ol 'hot melt adhesives', ol waia na kebol, na ol toi.
