Cov lus qhia ntxaws ntxaws

Ethylene-Vinyl acetate Copolymer, feem ntau sau raws li Eva, yog Copolymer tau ua los ntawm kev sib xyaw ua ke ntawm ethylene thiab vinyl acetate monomers. Nws yog cov khoom siv ntau yam siv hauv ntau cov ntawv thov vim nws lub zog xav tau.
EVA coploymer muaj lub siab yaj tsawg, yooj yim yooj yim, thiab kev sib npaug zoo ntawm kev muaj zog thiab elasticity. Nws tiv taus dej, UV hluav taws xob, thiab tshuaj lom neeg, uas ua rau nws haum rau kev siv sab nraum zoov. Nws tseem muaj cov nplaum zoo rau ntau cov substrates, ua rau nws zoo tagnrho rau kev siv ua phau ntawv lossis nplaum.
Ib qho ntawm cov ntsiab lus siv ntawm EVA yog nyob rau hauv kev tsim khoom ntawm foams. Nws yog dav siv los tsim cov ntaub ntawv cushioning thiab padding cov ntaub ntawv, xws li hauv khau, khoom siv kis las, thiab ntim cov khoom ntim. Eva foams muab lub zog ua kom puam tsuaj, poob siab, thiab kev nplij siab.
Eva coploymer tseem siv nyob rau hauv kev tsim cov yeeb yaj kiab thiab cov ntawv txheeb. Nws txoj kev paub meej, hloov tau yooj yim, thiab kev ua tau zoo ntawm kev siv rau cov tsev ntsuab npog, Laminated iav, thiab hnub ci Panels encapsulation.
Cov hluav taws xob thiab rwb thaiv tsev hluav taws xob ntawm Eva ua rau nws muaj txiaj ntsig hauv cov xaim thiab kev lag luam cable. EVA Txheej thiab Rwb thaiv tsev cov ntaub ntawv raug siv los tiv thaiv cov xov hlau thiab tsis muaj cuab kav cov ntawv thov ntawm Eva suav nrog cov khoom siv kho mob, khoom ua si.

Cov nplaum thiab cov xov xwm:Eva coploymer yog siv los ua cov khoom siv hauv paus hauv kev tsim cov nplaum thiab cov kab xev. Nws muab cov adasesion zoo rau ntau hom substrates, xws li plastics, cov hlau, thiab ntoo, ua kom haum rau kev siv nyiaj.
Hlau thiab Cable Rwb thaiv tsev:Eva tau siv los ua cov ntaub ntawv rwb thaiv cov hluav taws xob thiab cov hlau hluav taws vim nws cov khoom siv hluav taws xob zoo. Nws muab kev tiv thaiv kom noo, tshuaj lom neeg, thiab kev laus, kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov hluav taws xob.
Zaj duab xis thiab ntawv:Eva feem ntau yog siv los tsim cov yeeb yaj kiab thiab cov ntawv txheeb nrog sib txawv thicknesses. Cov yeeb yaj kiab no pom cov ntawv thov hauv kev ua liaj ua teb, tsev cog khoom npog, cov zaub mov ntim khoom, thiab cov kua tawg yaj.
Kho Mob:Eva tau siv nyob rau hauv kev lag luam kho mob los tsim cov cuab yeej kho mob, xws li tus atreters, tubing, thiab phais cov txheej txheem. Nws muaj biocompatibility, hloov tau yooj yim, thiab yooj yim qhov txheej txheem xav tau rau kev siv tshuaj kho mob.
Cov khoom ua si thiab khoom ua si:Eva tau dav siv hauv cov khoom ua si tsim khoom thiab cov khoom ua si, suav nrog kev ua npuas dej, khoom siv ua npuas dej, yoga mats, thiab ua npuas ncauj ua npuas dej. Nws muab lub zog cushioning, kev nyab xeeb, thiab kav ntev rau cov ntawv thov no.
Automotive Qhov:EVA cov ntaub ntawv ua npuas ncauj tau ua haujlwm hauv cov ntawv thov hauv lub suab rau cov suab rwb thaiv tsev, kev co damping, thiab kev tsis kam. Nws pab kom txwv lub suab nrov, txhim kho kev nplij siab, thiab muab kev tiv thaiv hauv tsheb hauv tsheb.
Cov no tsuas yog qee qhov piv txwv ntawm ntau cov kev siv ntawm Eva. Nws cov vagatility, yooj yim, thiab kav ntev ua nws tau siv dav siv cov khoom siv hauv kev lag luam ntau yam.
