Polyurethanes & Thermoplastics

Effect of Beta Irradiation on Mechanical Properties of Surface Layer of Injection Moulded High Density Polyethylene (HDPE)

The influence of beta radiation on the changes in the structure and selected properties (mechanical and thermal) polymers were proved. The specimens of high density polyethylene (HDPE) were made by injection moulding technology and irradiated by low doses of beta radiation (0, 33, 66, 99, 132, 165 and 198 kGy). more...

Plastics Recycling

Recycling of Polyethylene Terephthalate Plastic Wastes based on unsaturated Diol

Cis -2-buten-1,4-diol, as an aliphatic unsaturated alcohol, was used to depolymerize polyethylene terephthalate beverage bottles waste in presence of zinc acetate as a transesterification catalyst. The diolysis processes were carried out near the boiling point of the diol, at atmospheric pressure and under nitrogen flow for predetermined periods, namely 5 and 10 hours. more...
