Nui nā papa o PVC. ʻO ka viscosity a i ʻole K waiwai maʻamau i hoʻohana ʻia i ka ʻoihana e hōʻike ana i ka awelika molecular weight (a i ʻole degere awelika o ka polymerization) o PVC, ʻo ia hoʻi, ka lōʻihi o ke kaulahao mole PVC, ka mea e hoʻoholo ai i ka pae o ka resin a me nā ʻāpana hana e pili ana. ʻO ke kaumaha o ka molekala o ka resin e pili ana i nā waiwai kino a me nā mechanical o ka huahana.
ʻO ka resin PVC kahi ʻano o ka hui polymer linear non-crystalline. ʻOi aku ka nui o ka molecular mass, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka kiʻekiʻe o ka paona molekala, a ʻoi aku ka kiʻekiʻe o ka ikaika tensile, ka ikaika hopena, a me ka modulus elastic o ka huahana, akā hoʻoheheʻe ke kahe o ka resin. Hoʻohana mau ʻia ka helu viscosity e hōʻike i ke kaumaha molekala o ka polymer, a ua māhele ʻia ke kumu hoʻohālike polymer.
ʻO PVC ka mea i hoʻohana nui ʻia ma ka honua, a ua hoʻohana nui ʻia. Hoʻohana nui ʻia ia i nā mea kūkulu hale, nā huahana ʻoihana, nā mea e pono ai i kēlā me kēia lā, ka ʻili papahele, nā tile papahele, nā ʻili kūlohelohe, nā paipu, nā uea a me nā kaula, nā kiʻi ʻoniʻoni, nā ʻōmole, nā mea hupa, nā mea hoʻopaʻa, nā fibers, etc.
SG3 (K-70, S1300): hoʻohana nui ʻia no nā huahana palupalu, hoses, uea a me nā kaula, nā kiʻiʻoniʻoni, nā mea kāmaʻa, nā mea pāʻani, nā ʻāpana kaʻa etc.
ʻO PVC RESIN SG3 he maʻemaʻe kiʻekiʻe, liʻiliʻi nā maka iʻa, maʻalahi i ka blister, kiʻekiʻe wela ke kū'ē, insulation, soft product texture, etc. huahana.
