HDPE yog ib hom thermoplastic cob nrog high crystallinity thiab tsis-ncov qaumteb qabteb. Lub hauv paus xeev HDP
E's tsos yog cov xim dawb, hauv seem meager ntawm qee qhov kev kawm ntawm cov lus. PE muaj kev tiv thaiv zoo tshaj plaws rau feem ntau ntawm cov khoom ntawm kev noj qab haus huv thiab muaj chemical. Qee hom tshuaj muaj peev xwm tsim tau cov tshuaj lom neeg muaj corrosion, xws li oxidants corrosive oxidants (concentrated nitric acid), hydrocarbons (xylene) thiab halogenated hydrocarbons (carbon tetrachloride). Lub polymer tsis hygroscopic thiab muaj cov dej tsis haum thiab tsis siv tau rau ntim cov hom phiaj. HDPE yeej muaj hluav taws xob zoo, tshwj xeeb tshaj yog lub siab dielectric zog, yog li nws yog haum rau xaim thiab cable. Nruab nrab mus rau theem siab phaus qib siab muaj peev xwm ua tau zoo heev, nyob rau hauv chav sov txawm nyob -40f uas tsis tshua muaj siab. Cov yam ntxwv tshwj xeeb ntawm cov qib HDPE sib txawv yog qhov sib txuam ua ke ntawm plaub theem pib ua haujlwm: ntom, molecular luj, molecular luj faib thiab additive. Ntau hom catalysts siv los tsim kev cai tshwj xeeb polymers. Cov kev hloov no ua ke los tsim cov HDPE cov kev sib txawv ntawm cov kev siv thiab kom ua tau zoo rau kev ua kom tau zoo.
