One of the utmost man-made problems faced today has been the ever-increasing plastic waste filling the world. It accounts for an estimated 20-30% (by volume) of municipal solid waste in landfill sites worldwide. Research on plastic biodegradation has been steadily growing over the past four decades. Several fungi have been identified that produce enzymes capable of plastic degradation in variou...
The purpose of the study is to apply a previously developed model for predicting abrasive wear products made thermoplastic polyurethanes materials based on plasticized polyvinyl chloride. Confirmation validity proposed approach assess impact various factors weight reduction chloride (PVC). Comparative analysis polyurethane and PVC.
The important characteristics of polymer/clay nanocomposites are stability, barrier properties and in the case of polyvinyl chloride also plasticizer migration into other materials. Therefore, the permeation properties of polymer/clay nanocomposites are discussed in this paper. The attention was focused to the polyethylene (PE) and polyvinyl chloride (PVC). Natural type of montmorillonite MMTNa...
The photostabilization of polyvinyl chloride (PVC) films by Schiff bases was investigated. Polyvinyl chloride films containing 0.5 wt % Schiff bases were produced using the same casting method as that used for additive-free PVC films from tetrahydrofuran (THF) solvent. The photostabilization activities of these compounds were determined by monitoring the carbonyl, polyene and hydroxyl indices w...
Polyvinyl chloride (PVC) is one of the most widely used thermoplastics but also a material concern because generation and release harmful chemicals during its life cycle.
