Polyethylene cob yog tsim los ntawm polymerization ntawm monomer polyethylene. Vim muaj qhov sib txawv ntawm cov khoom siv polymerization xws li polymerization siab thiab kub, cov resins nrog qhov sib txawv tuaj yeem tau txais. Yog li ntawd, muaj cov polyethylene high-density, nruab nrab-density polyethylene thiab low-density polyethylene. Thaum ua cov yeeb nkab HDPE sib txawv, raws li kev thov sib txawv, cov qib sib txawv tau raug xaiv, thiab cov kev cai rau extruders thiab pwm kuj txawv.
