TPU (thermoplastic polyurethane) zaj duab xisyog ib lub siab -kev ua tau zoo elastic membrane uas sib txuas lub zog ntawm cov yas nrog rau qhov yooj ntawm cov roj hmab. Nws yog dav siv nyob rau hauv siab - daim ntawv thov kawg thoob plaws kev kho mob, kev lag luam, thiab cov neeg siv khoom lag luam.
Cov qauv ntawm TPU Composite Films
TPU tuaj yeem ua ke nrog ntau yam substrates los tsim cov yeeb yaj kiab nrog cov khoom siv sib txawv. Cov qauv uas muaj xws li:
TPU / PET- txhim khu kev ruaj ntseg, feem ntau siv hauv tsheb sab hauv.
TPU / Nylon- Txhim kho kev puas tsuaj rau sab nraum zoov thiab tiv thaiv iav.
TPU / Npuag (piv txwv li, polyester)- muab cov khoom muag muag, hloov tau yooj yim rau khau thiab khaub ncaws.
TPU / PE- txhim kho cov cua sov- sealing kev ua tau zoo rau kev kho mob thiab ntim tsis muaj menyuam.
Cov khoom tseem ceeb
High elasticity:Tensile elongation feem ntau ncav cuag 300% -600%, nrog zoo heev rebound.
Tsawg-kub yooj yim:Tseem mos ntawm -30 degree, outperforming PVC nyob rau hauv qhov chaw txias.
Abrasion thiab kua muag kuj:Haum rau cov ntawv thov raug cuam tshuam rau kev khoov thiab kev sib txhuam, xws li cov khoom siv khau.
Ib puag ncig tus phooj ywg:Tsis muaj cov yas yas thiab tuaj yeem ua tau raws li RoHS cov cai.
Zoo weldability thiab cua sov- sealing:Yooj yim rau kev ua cov duab complex.
Daim ntawv thov teb
Kev kho mob:
Breathable waterproof films kho mob rau kev phais lub tsho thiab lub qhov txhab.
Cov txheej txheej ntawm cov hlab ntsha kho mob xav tau yooj yim thiab ua kom tsis muaj menyuam.
Kev Ua Si & Sab Nraud:
Waterproof, breathable fabrics li lwm txoj rau Gore -Tex- hom laminates.
Inflatable khoom xws li nkoj, tiv thaiv iav, thiab cua cushions.
Industrial:
Automotive sab hauv laminations rau dashboards thiab airbag coatings.
Cov khaubncaws sab nraud povtseg rau cov khoom siv hluav taws xob hloov tau yooj yim thiab cov khoom lag luam.
Cov khoom siv:
Cov ntaub ntawv khau -TPU- laminated sab saum toj los txhim kho kev ruaj ntseg thiab kev txhawb nqa.
Shock -absorbing txheej rau cov xov tooj thiab cov khoom siv hluav taws xob nqa tau.
TPU Composite Film vs Lwm Elastic Films
| Khoom | TPU Composite Zaj duab xis | PVC Composite Zaj duab xis | TPE Film |
|---|---|---|---|
| Elasticity | Zoo heev | Nruab nrab | Nruab nrab |
| Tsawg-kev ua haujlwm kub | Mos ntawm -30 degree | Hardens nyob ib ncig ntawm -10 degree | Siv tau rau -20 degree |
| Environmental profile | Tsis yog - tshuaj lom, rov ua dua tshiab | Muaj cov yas yas (tej zaum yuav suav nrog DOP) | Ib nrab degradable |
| Nqi | Siab dua | Tsawg | Nruab nrab |
Cov txheej txheem ntau lawm
Extrusion tshuab:Molten TPU yog extruded los ntawm kev tuag thiab laminated nrog substrate.
Thermal lamination:TPU zaj duab xis yog sib txuas rau cov ntaub los ntawm cov rhuab rollers.
Txheej:TPU cov kev daws teeb meem los yog dispersions yog siv rau lub substrate thiab qhuav mus rau hauv ib tug niaj hnub zaj duab xis.
