Eji ngwaahịa
HQEE bụ ihe ndọtị nke aromatic diol yinye. Ọ nwere ike melite tensile, ike ike, ihe nkwụghachi azụ na MDI-polyurethane elastomers. HQEE/MDI bụ usoro PU elastomer yiri MOCA/TDI. Ngwaahịa emechachara dị ka: akara nke ọma mmanụ, taya forklift, eriri ebu, hydraulic cylinder seal na ọtụtụ ngwaahịa PU ndị ọzọ.
LCU elastomers chọrọ ihe abụọ ụkpụrụ: onye prepolymer kwụsịrị na otu isocyanate reactive na ihe ndọtị hydrogen na-akwụsị ọrụ. Prepolymer bụ ngwaahịa dabere na mmeghachi omume nke polyester ma ọ bụ polyether nwere isocyanate (TDI, MDI, ADI). Ihe ndọtị agbụ a na-abụkarị obere yinye diamine ma ọ bụ diol. A na-ejikarị diol agbatị MDI prepolymers.
