FTIR analysis of silane grafted high density polyethylene

FTIR analysis of silane grafted high density polyethylene

Oxygen-barrier films based on low-density polyethylene/ ethylene vinyl alcohol/ polyethylene-grafted maleic anhydride compatibilizer

In this research, high oxygen-barrier films were organized based on low-density polyethylene (LDPE)/ ethylene vinyl alcohol (EVOH)/ polyethylene-grafted maleic anhydride (LDPE-g-MA) compatibilizer. The effects of 10–30 wt. % EVOH and 0–10 wt. % LDPE-g-MA loadings on the properties of final films were evaluated. The morphology of specimens was observed by using scanning electron microscopy (SEM)...

Characterization and quantification of the cross-linking of linear low density polyethylene with silane grafting by Fourier transform infrared (FTIR) spectroscopy

The way of making cross-linkable polyethylene through silane grafting has gained much attention in recentyears because of its various advantages such as easy processing, low cost and capital investment andfavorable properties in the processed materials. This work deals with silane grafting and moisture crosslinkingof linear low density polyethylene (LLDPE). The grafting reaction was performed i...

Immobilization of Rhizomucor miehei Lipase on High Density Polyethylene

 Immobilization of Lipase produced from Rhizomucor miehei on HDPE fine powder was investigated. As compared to an aqueous system, immobilization in a non-aquous organic medium such as n-hexane was not successful and caused enzyme denaturation. Prewetting the support with ethanol increased the immobilized protein and enzyme activity as much as 31% and 34%, respectively. The maximum immobilized a...

Pyrolysis Kinetics of Waste High-density Polyethylene using Thermogravimetric Analysis

Thermal behavior of plastic materials can be improved by knowing thermal degradation kinetics for the optimal design and operation of pyrolysis process. In the present study, thermogravimetric analysis has been used for the non-isothermal kinetic study of waste high-density polyethylene pyrolysis under nitrogen atmosphere at different heating rates 10, 20 and 40 °C/min. The kinetic parameters, ...
