Thermal and mechanical properties of LDPE by the effects of organic peroxides

Abstract

In this study, the effect of different organic peroxides on different types of low‐density polyethylene (LDPE) was investigated. LDPE products like F2‐21T, F5‐21T, and I22‐19T were mixed in different proportions with dialkyl peroxide, dibenzoyl peroxide, and dilauroyl peroxide. Melt flow rates, mechanical properties (tensile strength at yield, tensile strength at break, elongation at break, and stress‐strain effect), thermal analysis (differential scanning calorimetric and thermogravimetric analysis), and scanning electron microscopy images of the prepared mixtures were examined. Cross‐linking occurred in the structure of LDPE types having different molecular weight distribution by the addition of even small amounts of peroxide (e.g. 0–0.12 wt%).

Characterization and determination of thermal and radioluminescence properties of low-density polyethylene (LDPE)-(nanozeolite + Y2O3) composite

“…PE is especially modified with the addition of nanocomposites which increase the polymers thermomechanical stability and chemical resistance. 1 Nanocomposites, the newest type of composite materials, are produced by dispersing the nanoparticles through the polymers. Nanocomposites are known to have superior properties than normal composites or basic polymers.…”

Polipropilen Blendlerinin Non-İzotermal Bozunma Kinetiği

“…Bu kapsamda son zamanlarda poliolefinler üzerinde istenilen özelliklerin elde edilmesi amacıyla pek çok çalışma yapılmıştır. Şirin ve ark çeşitli çalışmalarında eriyik halde farklı tip poliolefin malzemeler (HYPE-PP) içerisine CaCO3 dolgu maddesini ilave ederek kullanılan poliolefinlerin fiziko-mekanik özelliklerini iyileştirmeyi ve termal stabilitelerini artırmayı amaçlamışlardır [1][2][3][4]. Bir başka çalışmada Zsoldos ve Kollárpolyolefin/polimetilmetakrilat blendlerinin yapısal özelliklerini ve ısısal stabilitelerini araştırmışlardır [5].…”
