Hloov tshiab: 2025-10-22 · Qeb: TPU Kev Paub
TPU yog dab tsi?
TPU yog tsim los ntawm reacting diisocyanates nrog polyols thiab saw extenders. Qhov tshwm sim ntawm cov qauv polymer muab elasticity, lub zog, thiab tsis kam mus rau roj thiab puas. Chemically, TPU zaum ntawm cov roj hmab muag thiab cov yas tawv - muab cov txiaj ntsig ntawm ob qho tib si.
Cov yam ntxwv tseem ceeb ntawm TPU
- High Elasticity:TPU tuaj yeem ncav cuag 600% yam tsis muaj kev tawg.
- Abrasion Resistance:Ntau dua li PVC lossis roj hmab.
- Huab cua thiab tshuaj tiv thaiv:Ua tau zoo nyob rau hauv huab cua kub thiab av noo.
- Kev ua haujlwm yooj yim:Haum rau kev txhaj tshuaj molding, extrusion, lossis tshuab moulding.
TPU vs EVA vs PVC vs Roj Hmab - Cov khoom tseem ceeb sib piv
| Khoom | TPU | EVA | PVC | Roj hmab |
|---|---|---|---|---|
| Elasticity | ★★★★★ (Zoo heev) | ★★★★☆ (Zoo) | ★★☆☆☆ (Tsawg) | ★★★★☆ (Zoo) |
| Abrasion Resistance | ★★★★★ (Zoo heev) | ★★★☆☆ (Nruab nrab) | ★★☆☆☆ (Tsawg) | ★★★☆☆ (Nruab nrab) |
| Nyhav / ntom | ★★★☆☆ (Medium) | ★★★★★ (Lub teeb heev) | ★★★☆☆ | ★★☆☆☆ (Hnyav) |
| Huab cua Resistance | ★★★★★ (Zoo heev) | ★★★★☆ (Zoo) | ★★★☆☆ (Average) | ★★★★☆ (Zoo) |
| Ua Flexibility | ★★★★★ (Kev Txhaj Tshuaj / Extrusion) | ★★★★★☆ (Foom) | ★★★★★☆ | ★★☆☆☆ (Limited) |
| Kev rov ua dua tshiab | ★★★★★☆ | ★★★☆☆ | ★★★☆☆ | ★★☆☆☆ |
| Tej kev siv | Khau khau, cables, films | Midsoles, ua npuas ncauj | Cables, nag khau looj plab hlaub | Cov log tsheb, gaskets |
Nco tseg:Kev ntsuam xyuas yog txheeb ze rau kev sib piv yooj yim. Cov ntaub ntawv tiag tiag nyob ntawm qib thiab cov txheej txheem ua haujlwm.
TPU muab kev tiv thaiv zoo tshaj plaws thiab lub zog, thaum EVA muab lub zog cushioning. PVC thiab roj hmab tseem muaj txiaj ntsig zoo rau cov nqi-sensitive lossis tshwj xeeb siv.
Cov ntawv thov siv
- Khau khau:Soles thiab midsoles rau kev ua kis las thiab khau kev nyab xeeb.
- Cables:Flexible, tawg-resistant cable tsho rau sab nraum zoov siv.
- Zaj duab xis:Pob tshab TPU zaj duab xis rau lamination, tiv thaiv, lossis siv kho qhov muag.
- Automotive:Dashboards, sab hauv trims, thiab iav pob qhov rooj.
- Kev kho mob:Biocompatible TPU tubing thiab daim nyias nyias.
Vim li cas thiaj xaiv TPU?
Piv nrog cov khoom siv niaj hnub xws li PVC lossis EVA, TPU muaj lub zog zoo dua, ua kom tsis muaj zog, thiab yoog raws. Nws kuj tseem muab kev txhim kho kev ruaj khov, vim nws tuaj yeem rov ua dua thiab rov siv dua yam tsis muaj kev ua haujlwm loj.
Xaus
TPU txuas qhov sib txawv ntawm cov roj hmab muag thiab cov yas tawv. Nws qhov sib npaug ntawm qhov yooj yim thiab tawv ua rau nws yog ib qho kev xaiv hauv khau, cable, thiab kev lag luam tsheb.
