QHM32F yog polyethylene resin nrog hexene-1 ua co-monomer tsim los ntawm Unipol txheej txheem ntawm UCC, USA.Nws muaj qhov zoo ntawm kev ua haujlwm zoo, kev ua haujlwm zoo, thermal stability thiab siab ua haujlwm.Feem ntau yog siv rau kev tsim cov yeeb nkab hauv pem teb, aluminium - yas puas yeeb nkab, hnub ci raj.

PE-RT yeeb nkab yog ib yam tshiab ntawm cov khoom siv tsis yog crosslinked polyethylene uas tuaj yeem siv rau hauv cov kav dej kub.Nws yog ib tug copolymer ntawm ethylene thiab octene uas tsim los ntawm tshwj xeeb molecular tsim thiab synthesis txheej txheem, nrog ib tug controllable tooj ntawm ceg saw thiab tis qauv ntawm polyethylene ntau yam.Cov qauv molecular tshwj xeeb ua rau cov khoom muaj kev ntxhov siab tawg zoo heev thiab lub zog hydrostatic ntev.PE-RT yeeb nkab muaj qhov hloov tau zoo, thiab nws cov qauv khoov yog 550 MPa, thiab cov kev ntxhov siab sab hauv tsim los ntawm kev khoov qis.Nyob rau hauv txoj kev no, nws raug zam tias cov yeeb nkab yuav raug puas ntsoog ntawm qhov chaw khoov vim muaj kev ntxhov siab.Thaum tsim kho (tshwj xeeb tshaj yog nyob rau lub caij ntuj no), nws tsis tas yuav muaj cov cuab yeej tshwj xeeb lossis cua sov kom khoov.Thermal conductivity ntawm 0. 4 W / (m·k), piv rau PE-X raj, ntau dua PP-R 0. 22 W / (m·k) thiab PB 0. 17 W / (m·k), zoo heev thermal conductivity, haum rau pem teb cua sov yeeb nkab
