Ntev iav Fiber Filling TPU Thermoplastic Polyurethane Composite Khoom

Thermoplastic polyurethane elastomer, tseem hu ua thermoplastic polyurethane roj hmab, TPU luv luv, yog A (AB) N-hom block linear polymer, A yog qhov hnyav molecular (1000 ~ 6000) polyester lossis polyether, B yog diol muaj 2 ~ 12 ncaj saw carbon atoms, AB saw chemical qauv yog diisocyanate.

Thermoplastic polyurethane roj hmab yog cross-linked los ntawm intermolecular hydrogen bonds los yog me ntsis cross-linking ntawm macromolecular chains. Nrog rau qhov nce lossis txo qis ntawm qhov kub thiab txias, ob qho kev sib txuas sib txuas no muaj cov khoom thim rov qab. Nyob rau hauv lub xeev molten los yog lub xeev kev daws teeb meem, lub zog intermolecular tsis muaj zog, thiab tom qab txias los yog hnyav volatilization, muaj ib tug muaj zog intermolecular quab yuam txuas ua ke, restores cov kev ua tau zoo ntawm cov khoom qub. Hom TPU xws li spandex.

Feature

High toughness, siab rigidity, tsis tshua muaj dej nqus, siab dimension stability, tshuaj tsis kam, thiab zoo cov khoom zoo li.

Daim ntawv thov

Lub tsheb qhov rooj thiab qhov rais, kev nyab xeeb ntiv taw, cov khoom siv kho tshuab, pneumatic ntsia thawv phom, cov cuab yeej siv hluav taws xob, cov txiv ntseej, bolts, thiab lwm yam.

Polyurethane thermoplastic elastomer yog tus cwj pwm los ntawm kev hnav zoo heev, zoo heev ozone kuj, siab hardness, siab zog, zoo elasticity, tsis kub tsis kam, zoo roj tsis kam, tshuaj tsis kam, thiab ib puag ncig kuj. Nyob rau hauv ib qho chaw ntub dej, qhov kev ruaj ntseg hydrolysis ntawm polyether ester yog ntau tshaj li ntawm polyester hom.
