POLYESTER POLYOL NO PPU
ʻO nā polyols polyester me ke kaumaha molekala o 500-4000G / Mol nā mea maikaʻi o ka chromaticity haʻahaʻa a me ka hana paʻa.ʻO ka TPU i hana ʻia mai ka polyester polyols nā mea maikaʻi o ka viscosity paʻa, ʻoki maʻalahi, ikaika mechanical maikaʻi, kūpaʻa ʻaʻahu kiʻekiʻe, kūʻē i ka waimaka a me ka hoʻololi wikiwiki ʻana, a hiki ke hoʻoponopono i ke kaumaha molekala e like me nā koi o ka mea kūʻai aku.
Hiki ke hoʻohana nui ʻia kēia moʻo polyester polyols i ka TPU elastomer wela hoʻoheheʻe adhesive, mea kāmaʻa, paipu, kiʻiʻoniʻoni, kaula kaula, kāʻei conveyor a me nā huahana polyurethane ʻē aʻe.
