ʻO ka PVA glue ka pōkole o Polyvinyl acetate.He pauda keʻokeʻo ka helehelena.He ʻano polymer hiki ke hoʻoheheʻe ʻia me ka nui o ka hoʻohana ʻana.ʻO kāna hana ma waena o ka plastic a me ka rubber.Hiki ke hoʻokaʻawale ʻia kona hoʻohana ʻana i ʻelua hoʻohana nui: fiber a me non-fiber.Ma muli o ka PVA he kū hoʻokahi ikaika adhesion, hoʻololi kiʻiʻoniʻoni, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, abrasion resistance a me ka wai kū me ka hoʻomaʻamaʻa kūikawā, ʻaʻole ia i hoʻohana wale ʻia e like me ka fiber raw material , Hoʻohana nui ʻia i loko ka hanaʻana i nā uhi, nā mea hoʻopili, nā mea hana pepa, nā emulsifiers, dispersants, nā kiʻiʻoniʻoni a me nā huahana'ē aʻe, me nā noi e uhi ana i nā textiles, nā meaʻai, nā lāʻau lapaʻau, ke kūkuluʻana, ka hana lāʻau, ka pepa, ka paʻiʻana, ka mahiʻai, ke kila, Polymer chemical industry a me nāʻoihana'ē aʻe.
Ke hoʻohālikelike ʻia me nā mea hoʻopili like ma ka mākeke, ʻaʻole i loaʻa nā mea ʻona e like me formaldehyde (e hoʻohana ana i ka resin urea-formaldehyde i hoʻololi ʻia a i ʻole melamine resin a i ʻole ka wai-soluble phenolic resin e hiki ke hōʻea i ka mālama ʻana i ke kaiapuni E2 a i ʻole. Hiki ke ho'ēmi i ka formaldehyde maʻiʻo manuahi o ka huahana), ʻaʻohe haumia i ka hana ʻana a me ka hoʻohana ʻana i ke kaiapuni, ke kumu kūʻai haʻahaʻa, ke kaʻina hana maʻalahi, ka hopena paʻa maikaʻi, ka maloʻo wikiwiki a me ka wikiwiki paʻa.Hoʻohana ʻia ia no ka hana ʻana i ka papa lāʻau me ka ʻole o ke kaomi wela a loaʻa nā pōmaikaʻi nui i ka mālama ʻana i ka ikehu.
