POLYESTER POLYOL maka CPU
The polyester polyols na molekụla arọ nke 500-4000G/Mol nwere uru nke ala chromaticity na kwụsiri ike ọrụ.TPU emere site na polyester polyols nwere uru nke viscosity kwụsiri ike, ịcha dị mfe, ike igwe dị mma, oke mgbochi akwa, nguzogide akwa na ịkpụzi ngwa ngwa, ma nwee ike ịhazigharị ịdị arọ molekụla dị ka ihe ndị ahịa chọrọ.
Usoro a nke polyester polyols nwere ike iji ya mee ihe na TPU elastomer na-ekpo ọkụ gbazee nrapado, ihe akpụkpọ ụkwụ, ọkpọkọ, ihe nkiri, eriri USB, eriri ebu na ngwaahịa polyurethane ndị ọzọ.
