Hla-txuas polyethylene yog ib qho thermosetting yas nrog cov qauv mesh. Nws muaj qhov hnav tsis kam, hnyav ua haujlwm, qhov ruaj khov, kev ntxhov siab tawg ua haujlwm, kev laus ua haujlwm thiab huab cua tsis kam. Nws yog non-toxic, odorless thiab non-absorbent. Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias thiab ua kom sov zoo heev. Qhov taw tes softening tuaj yeem ncav cuag 200 degree thiab nws tuaj yeem siv tau ntev ntawm 140 degree. Nws qhov cuam tshuam lub zog, tensile lub zog, nkag siab thiab rigidity yog zoo dua HDPE, thiab nws elastic modulus yog 5 npaug siab dua HDPE. Nws muaj cov rwb thaiv tsev zoo heev, kub tsis kam, tshuaj lom neeg ruaj khov thiab hluav taws xob tiv thaiv. Nws cov yeeb yaj kiab muaj qhov pom tseeb nruab nrab thiab cov dej vapor permeability txaus. Tom qab cua sov, inflating (stretching), txias thiab shaping, cross-linked polyethylene tuaj yeem rov qab los rau nws cov duab qub thiab qhov loj me (piv txwv li, nws muaj lub cim xeeb zoo) thaum nws rov ua dua saum qhov kub ntawm crystallization. Feem ntau siv cross-linked polyethylene nyob rau hauv kev lag luam yog hluav taws xob cross-linked polyethylene, peroxide cross-linked polyethylene thiab silane cross-linked polyethylene. Kev ua tau zoo ntawm hluav taws xob hla-txuas polyethylene zaj duab xis.

Organic peroxide cross-linked polyethylene yog txawv ntawm cov thermoplastics, thermosetting resins thiab vulcanized roj hmab hauv cov qauv. Nws muaj lub cev qauv tab sis tsis yog kev sib txuas tag nrho. Qhov chaw sib txuas yog qhov me me, tsis zoo li cov roj hmab vulcanized, uas muaj qhov sib txuas loj loj. Yog li ntawd, nws muaj cov yam ntxwv ntawm peb yam ntawm kev ua tau zoo, uas yog, nws muaj thermoplasticity, hardness, zoo hnyav kuj, siab elasticity thiab zoo heev kub tsis kam. Txawm hais tias nws yog polyethylene high-density polyethylene los yog tsawg-density polyethylene, tom qab kev sib txuas, nws lub zog tensile, tshav kub tsis kam, kev laus ua haujlwm thiab huab cua tsis kam, qhov ntev stability, kev ntxhov siab tawg ua haujlwm, hnav tsis kam thiab hnyav ua haujlwm yog txhua yam txhim kho, thiab nkag mus. tsis kam yog zoo heev. Lub softening point ntawm cross-linked polyethylene tuaj yeem ncav cuag 200 degree, thiab cov cua sov tuaj yeem ncav cuag 140 degree. Tsis tas li ntawd, nws kuj muaj cov hluav taws xob rwb thaiv tsev zoo heev, tsis tshua muaj kub thiab hluav taws xob tiv thaiv. Kev ua tau zoo ntawm peroxide cross-linked polyethylene.
