ʻO ka hana nui o nā mea kelepona PVC ka mea nui i loaʻa:polyvinyl chloride resin, dioctyl phthalate, stabilizer, plasticizer, inorganic filler, filler, lubricant, antioxidant, colorant, etc., i hoʻomākaukau ʻia e ka hui ʻana a me ke kāwili ʻana a me ka extrusion.
Aia ma waena o 50PHR a me 60PHR ka ʻikepili plasticizer.E koho pinepine i ka pale wela a me ka hana hoʻokaʻawale uila o ka plasticizer maikaʻi loa i mea e hoʻomaikaʻi maikaʻi ai i ka pale wela hiki ke hoʻohui ʻia i trioctyl metapentriacid.Loaʻa ka hopena maikaʻi loa i nā ʻano plasticizer i hoʻohana pū ʻia.ʻO ka ʻoiaʻiʻo, hoʻohana pū ʻia nā plasticizers i ka PVC cable material formula.ʻO nā mea kelepona PVC me ka insulation ikaika hiki ke koho i ka ester phosphate ma ke ʻano he mea nui, a ʻo ka ester benzoate e like me ka mea nui e kūpono no ka papa maʻamau.ʻO ke kūpaʻa wela a me ke kūpaʻa volatile o ka plasticizer nā mea hoʻoholo no ka pale wela kiʻekiʻe o nā mea kelepona.
