EPP high-density ib puag ncig tus phooj ywg cov khoom yog cov khoom siv crystalline polypropylene ua npuas ncauj nrog kev ua tau zoo heev. Nrog nws cov cim tshwj xeeb thiab kev ua tau zoo tshaj, nws tau dhau los ua qhov nrawm tshaj plaws tshiab ntawm ib puag ncig tus phooj ywg siab-resistant buffering thiab thermal rwb thaiv tsev khoom. EPP cov khoom muaj kev poob siab-tiv taus lub zog-absorbing zog, siab rov qab tus nqi tom qab deformation, zoo kub tsis kam, tshuaj tsis kam, roj kuj thiab rwb thaiv tsev kub. Tsis tas li ntawd, lawv lub teeb hnyav tuaj yeem txo qhov hnyav ntawm cov khoom.
EPP ua npuas ncauj ntim yog ib qho kev ua haujlwm siab-resistant buffering thiab cov khoom siv hluav taws xob uas muaj lub cev zoo, cov khoom siv tshuaj ruaj khov, thiab rov ua dua tshiab. Nws yog tam sim no tsuas yog siv hauv IT khoom ntim khoom, khoom siv sib txuas lus thiab tsheb. EPP ib puag ncig tus phooj ywg cov khoom ntim muaj cov yam ntxwv ntawm lub teeb tshwj xeeb lub ntiajteb txawj nqus, zoo elasticity, poob siab tsis kam thiab compression tsis kam, siab deformation rov qab tus nqi, zoo nqus dej ua haujlwm, roj tsis kam, acid tsis kam, alkali tsis kam, tsis kam mus rau ntau yam tshuaj hnyav, uas tsis yog-absorbent, rwb thaiv tsev, kub tsis kam (-40 ~ 130 degree), tsis muaj tshuaj lom thiab tsis qab.
Cov khoom siv EPP muaj qhov ua haujlwm kub zoo heev, thiab qhov siab tshaj plaws ua haujlwm kub yog 130 degree, uas yog siab tshaj qhov kub ntawm EPS thiab EPE. EPP muaj qhov me me thermal shrinkage thiab yog qhov ruaj khov. Tus txheeb ze ntom ntom ntawm EPP yog me me thiab nws yog sib dua li lwm yam ntaub ntawv ua npuas ncauj ntawm tib foaming piv. EPP muaj zoo toughness thiab tsim nyog hardness, thiab muaj zoo heev cushioning zog.
Cov khoom siv EPP yog cov khoom siv crystalline polymer / roj sib xyaw nrog cov khoom zoo heev. Nrog nws qhov tshwj xeeb thiab kev ua tau zoo tshaj, nws tau dhau los ua qhov nrawm tshaj plaws tshiab ntawm ib puag ncig tus phooj ywg siab-resistant tsis muaj rwb thaiv tsev cov khoom. EPP kuj yog ib qho khoom zoo rau ib puag ncig thiab tuaj yeem siv dua. Qhov zoo ntawm EPP cov ntaub ntawv zoo ib puag ncig muaj xws li: ib puag ncig tus phooj ywg thiab kev nyiam huv, tsis muaj tshuaj lom thiab tsis muaj ntxhiab, tuaj yeem siv dav hauv ntim khoom noj, thiab yooj yim thiab yooj yim rau rov ua dua.
