Cov khoom zoo li cas tsis muaj cov tshuab elastomer polyurethane
Qhov loj tshaj plaws ntawm cov thermoplastic polyurethane elastomers yog tias lawv yog cov ywjpheej thiab muaj lub zog zoo thaum lub sijhawm ua kom muaj kev sib zog. Lub zog ntawm thermoplastic polyurethane elastomer feem ntau yog 30 ~ 45MPa, thiab pob zeb tawg yog feem ntau ntawm 400 ~ 800%. ntau npaum li cas los ntawm 65A rau 80D ua rau cov khoom pauv hloov .Ntawm, raws li cov kev ua kom muaj zog, cov ntaub npog ntsej muag ua kom pom tseeb: lub zog thiab lub zog ntxiv zuj zus;
Cov thermoplastic polyurethane elastomers tau zoo heev tearing kuj, thiab rhuav lub zog yog hais txog tensile zog (txawm tias tsis proportional), thiab nce nrog rau kev nce ntawm polymer hardness.
Cov kev sib txuam thiab cov cuab yeej ntawm cov thermoplastic polyurethane elastomers uas muaj feem xyuam rau hom polymer, crosslinking degree, post-vulcanization los yog lub cev hloov kho.Thermoplastic polyurethane elastomers nrog me ntsis crosslinking yuav tau txo compression lub cev deformation qhov tseem ceeb, tshwj xeeb tshaj yog thaum kub dua.Qhov post- Kev siv cov ntaub qhwv to taub tau zoo heev kom txo qhov kev sib deev, tshwj xeeb tshaj yog cov deformation ntawm qhov siab.
