Mirathane® Polycarbonate-TPU dabere

Polycarbonate diols bụ ụdị polyols nwere ọmarịcha akụrụngwa zuru oke, na ụdọ molekụla ha nwere nkeji ugboro ugboro dabere na carbonate. N'ime afọ ndị na-adịbeghị anya, a na-ewere ha dị ka akụrụngwa maka ọgbọ ọhụrụ nke thermoplastic polyurethane elastomers. Ya mere, dị ka akụkụ dị nro, ọ na-arụ ọrụ dị mma n'akụkụ niile nke TPU polycarbonized na-ejikọta ya na isocyanate na chain extender.

E jiri ya tụnyere polyester TPU, ọ bụghị nanị na ọ nwere ike dị elu, nnukwu okpomọkụ na-eguzogide na àgwà ndị ọzọ, kamakwa ọ nwere ezigbo nguzogide hydrolysis. E jiri ya tụnyere polyether TPU, ọ bụghị naanị na ọ nwere nguzogide hydrolysis dị mma, kamakwa ọ nwere ike dị elu, nkwụsị ọkụ ka mma na nkwụsi ike oxidation ka mma.

N'ihi arụmọrụ ya dị mma, n'ime afọ ndị na-adịbeghị anya, a na-ejikarị polycarbonized TPU eme ihe na mmepụta mmepụta ihe, ihe ahụike na mpaghara ndị ọzọ. N'iji nkwụsi ike ya, ike dị elu, ezigbo okpomọkụ na-eguzogide, hydrolysis resistance, enwere ike iji ya dị ka taya n'okpuru mmiri na ihe ndị ọzọ pụrụ iche. N'iji nguzogide hydrolysis ya, ike dị elu, nkwụsị oxidation, wdg, ọ nwere ike ịmepụta ọkpọkọ chlorine pụrụ iche na ngwaahịa mmepụta ihe ndị ọzọ. Site na nguzogide oxidation na nkwụsi ike ya dị mma na ahụ mmadụ, enwere ike iji ya dị ka ụdị ihe ọkụkụ ọhụrụ nke ọgwụ.

Site na ọtụtụ afọ nke mmepe nyocha na ahụmịhe mmepụta, Miracll nwere ike mepụta usoro siri ike nke 80A-95A nke Polycarbonate TPU dịka C80, C85, C90, C95.

N'ọdịnihu, anyị ga-emepụta ihe ọhụrụ kachasị mma dịka ebumnuche na gburugburu dị iche iche si dị.
