Cov yam ntxwv thiab cov yam ntxwv ntawm blister tshuab blister khoom xim ntawv polyethylene

Polyethylene yog ib hom thermoplastic, uas tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom, flammable dawb hmoov. Lub molded PE resins yog tag nrho cov extruded thiab granulated waxy granules nrog milky dawb tsos. Nws qhov hnyav molecular yog nyob rau hauv thaj tsam ntawm 10,000 txog 1,000,000. Cov uas muaj qhov hnyav molecular ntau dua 100,000 yog ultra-high molecular hnyav polyethylene f UHMWPE3. Qhov siab dua qhov hnyav molecular, qhov zoo dua nws lub cev thiab cov khoom siv kho tshuab, thiab ze rau qib yuav tsum muaj cov khoom siv engineering. Tab sis qhov siab dua qhov hnyav molecular, qhov nyuaj dua nws yog ua. Lub melting point ntawm polyethylene yog 100-130C. Nws qhov kub tsis kam yog qhov zoo heev. Nws tseem tuaj yeem tswj tau cov khoom siv kho tshuab zoo ntawm -60 degree, tab sis kev khiav hauj lwm kub yog 80 ~ 110 degree .
