Pangigapo ed EVA Hot Melt Adhesive

Say EVA hot melt adhesive et anggapoy solvent-, anggapoy danum, 100% solido, tan natunaw ya polymer. Solid itan ed temperatura na kuarto tan natunaw pian magmaliw ya onaagus tan malet ya likidon adhesive no napetang ed sakey a grado. Kayari ton natunaw, saya et magmaliw ya light brown, translucent odino off-white ya substansia. Say manunan kabiangan na hot melt adhesive, say basic resin, et sakey a copolymer na ethylene tan vinyl acetate ya walad silong na atagey a presyon, ya inlaok ed saray tackifier, viscosity modifiers, antioxidants, tan arum ni, pian nagawa so hot melt adhesive.

Say EVA et sakey a plastik ya materyales ya gawad ethylene (E) tan vinyl acetate (VA). Say ratio na sarayan duaran kemikal et nayarin i-adjust pian nasumpal so nanduruman pankaukolan ed aplikasyon. Say mas atagey ya vinyl acetate (VA content) et manresulta ed mas malinew ya transparency, inka-anlemew, tan inka-tough.

Say ethylene-vinyl acetate copolymer (ya tatawagen met ya ethylene-vinyl acetate copolymer) et naala diad panamegley na copolymerizing ya ethylene (E) tan vinyl acetate (VA). Say Ingles ya ngaran to et Ethylene Viny Acetate, ya pinatikeyan ya EVA o E/VAC. Saray paraan na polimerisasyon et kaiba so high-pressure bulk polymerization (parad plastik), solution polymerization (PVC processing aids), emulsion polymerization (adhesives), tan suspension polymerization. Say emulsion polymerization et uusaren parad vinyl acetate (VA) ya mas atagey nen say 30%, bangta say high-pressure bulk polymerization et uusaren parad abeban VA content. Say EVA et walaan na nanduruman aplikasyon.

Kaslakan, say EVA ya walay vinyl acetate ya abeba nen 5% so manunan uusaren parad saray pelikula, LDPE modifiers parad saray alambre tan kable, tan saray adhesives; Say EVA ya walay vinyl acetate ya 5%-10% et uusaren parad saray elastic film; Say EVA ya walay vinyl acetate ya 20%-28% et manunan uusaren parad hot melt adhesives tan coating products; tan say EVA ya walay vinyl acetate ya 5%-45% et manunan uusaren parad saray pelikula (kaiba iray agricultural films) tan sheets, injection molded tan molded products, foamed products, tan hot melt adhesives. Saya so malaknab ya uusaren ed saray foamed shoe materials, functional greenhouse films, packaging molds, hot melt adhesives, wires tan cables, tan saray kagawaan.
