Polyethylene (PE)
Pob tshab: cov kua dawb ntawm translucent, waxy thaum tsis xim.
Nta: Cov khoom ua tau zoo los ntawm tes, qhov muag thiab tawv. Feem ntau, tsis muaj qhov hnyav polyethylene yog mos thiab muaj kev kaj zoo; high density polyethylene yog ib qho nyuaj.
Cov Khoom: cov hnab tes, cov kav dej, cov roj drums, dej haus hwj (calcium mis nyuj fwj), cov khoom siv txhua hnub, thiab lwm yam.
Polypropylene (PP)
Pob tshab: dawb, translucent, waxy thaum tsis xim.
Nta: Sib dua li ntawm cov polyethylene, daim nplaj yog qhov zoo dua polyethylene, nyuab dua polyethylene.
Khoom: phiab, tej kas tham, rooj tog zaum, zaj duab xis, lub hnab ntim, lub raj mis, tsheb thawv, thiab lwm yam.
Polystyrene (PS)
Pob tshab: Poob thaum tsis muaj xim.
Nta: Cov khoom yog grounded los yog raug ntau, nrog lub suab zoo li lub suab zoo, zoo gloss thiab transparency, zoo li iav, nkig thiab yooj yim tawg, cov ntiv tes yuav ua raws li cov nplais ntawm cov khoom. Cov hloov polystyrene yog opaque.
Khoom siv: ntawv sau, khob, khoom noj khoom haus, khoom siv tsev, khoom siv hluav taws xob, thiab lwm yam.
Polyvinyl chloride (PVC)
Pob tshab: Cov xim yog xim daj thiab cov ntawv ci.
Nta: Transparency yog zoo dua li polyethylene, polyphenylene, thiab zuj zus tshaj li cov pob zeb polystyrene. Nws tau muab faib ua cov mos mos thiab cov nyom polyvinyl chloride raws li qhov nyiaj cov additives. Cov khoom muag muag muag muag muag muag muag, muag, muag, thiab lwm yam. qhov hardness ntawm cov khoom tawv yog siab tshaj qhov uas tsis tshua muaj qhov hnyav polyethylene, thiab qis dua li ntawm cov polypropylene, ntxuav hniav dawb tuaj nyob ntawm qhov kis sib kis.
Khoom: plates, kav dej, sab laug, khoom ua si, qhov rooj thiab lub qhov rais, xaim hluav taws xob, ntawv sau, thiab lwm yam.
Polyethylene terephthalate (PET)
Pob tshab: Transparency zoo.
Nta: Lub zog thiab kev muaj zog yog zoo dua polystyrene thiab polyvinyl chloride, tsis yooj yim mus ua txhaum.
Khoom: zaub mov ntim cov khoom noj, cov khoom siv fwj, xws li cola, fwj pob zeb dej, thiab lwm yam.
