A na-akpọkarị roba polybutadiene mmiri mmiri Carboxyl kwụsịrị CTPB maka mkpụmkpụ. N'ihi na e nwere carboxyl na nsọtụ abụọ nke molekul polymeric, polymer a na-arụ ọrụ nhazi n'akụkụ otu carboxyl, nkesa nke netwọk ahụ dị mma na enweghị nkwụsị ọ bụla. n'ihi ya, ọ nwere magburu onwe n'ibu arụmọrụ.
Otu njedebe nke carboxyl nwere ike iji resin epoxy meghachi omume, nke nwere mmetụta siri ike na resin epoxy. E jiri ya tụnyere CTBN, CTPB nwere viscosity dị ala, arụmọrụ dị ala nke ọma na mgbanwe mgbanwe.
Ọ bụghị naanị na enwere ike iji ngwaahịa a na rọketi siri ike, kamakwa enwere ike iji ya na elastomers, adhesives, sealing material, epoxy resin modification na ihe na-egbochi ọkụ eletrik.
Ejiri ya na 50kg / drum, 180kg / drum, Oge nchekwa bụ 1 afọ.
