Hauv kev lag luam hlau thiab cable, kev xaiv cov khoom siv ncaj qha cuam tshuam rau kev ua haujlwm, kev ua neej thiab nqi ntawm cov khoom. Nyob rau hauv xyoo tas los no, TPE (thermoplastic elastomer) thiab silicone tau txais kev pom zoo raws li ob lub siab -kev ua haujlwm sheathing thiab rwb thaiv tsev cov ntaub ntawv. Txhua tus ntawm lawv muaj nws tus kheej zoo thiab kev txwv.
1. Cov khoom siv yooj yim
|
Yam ntxwv |
TPE |
Silicone |
|
Cov qauv tshuaj |
Thermoplastic elastomer (ib qho sib xyaw ntawm cov yas thiab roj hmab) |
Thermosetting elastomer (siloxane polymer) |
|
Txoj kev ua |
Txhaj tshuaj molding, extrusion (recyclable) |
Compression molding, extrusion (yuav tsum tau vulcanization, tsis recyclable) |
|
Hardness ntau yam |
Ntug A 30 ~ 90, kho tau |
Ntug A 20 ~ 80, kho tau |
2. Kub kam rau ua
TPE: Qhov kev ua haujlwm kub ib txwm nyob ntawm -40℃mus rau +90℃. Nrog cov qauv tsim tshwj xeeb, nws tuaj yeem ncav cuag +120℃.
Silicone: Kev ua haujlwm ntau yog -50℃rau +200℃. Nws muaj superior siab -kub stability thiab low-temperature elasticity.
3. Yooj yim thiab elasticity
TPE: Zoo elasticity, qis khoov modulus, me ntsis inferior nyob rau hauv rov qab elasticity piv rau silicone.
Silicone: Cov mos mos heev, nrog tsawg kawg deformation thaum compression, thiab zoo heev rov qab elasticity.
4.Kev ua haujlwm thiab ib puag ncig tus phooj ywg
TPE: tuaj yeem ncaj qha extruded lossis txhaj tshuaj- molded, recyclable, tsis muaj vulcanization txheej txheem, nrog tsawg zog noj.
Silicone: Yuav tsum muaj siab -kub vulcanization (nrog peroxide lossis platinum catalyst), tsis tuaj yeem rov ua dua, thiab muaj pov tseg los ntawm cov khoom seem.
