The effect of plant-based fillers on thermal resistance in highly filled biocomposites based ethylene-vinyl acetate copolymer (EVA) was studied. Wood flour and microcrystalline cellulose were used as fillers. It shown that the introduction into EVA did not affect stability polymer matrix. In contrast, wood led to a significant increase entire biocomposite. Oxidation induction time increased from 0 (pure EVA) 73 min (EVA + biocomposites). low-molecular weight phenolic compounds contained are...

Biodegradability of five commercial plastic bags labelled as "biodegradable" and two referent materials were studied by a soil test for three months. As control experiment, studying abiotic degradation under the climatic impact (ultraviolet, temperature, moisture) in weatherometer was performed. The changes bag samples after tests detected optical microscopy, Fourier-transform infrared spectroscopy, differential scanning calorimetry, tensile testing. It found that all may be separated into...

Highly filled biocomposites may be used as biodegradable masterbatches that manufacturers add to traditional polymers for making plastic goods more biodegradable. Biocomposites based on various trademarks of ethylene-vinyl acetate copolymer (EVA) and natural vegetable fillers (wood flour microcrystalline cellulose) were studied. The EVA differed both in terms the melt flow index content vinyl groups. composites created superconcentrates (or masterbatches) production materials with polyolefin...

This review considers the recent investigations in scope of biodegradability synthetic polymers, spanning polyethylene (PE), polypropylene (PP), and their corresponding composites, with a focus on influence oxo-additives (mostly transition metal salts). The types mechanisms oxidation acceleration are discussed. Furthermore, both physicochemical biological stages degradation is evaluated (laboratory field experiments microorganisms/fungi action) standards suggested for estimation. Comparisons...

The paper is devoted to investigation of deterioration natural fillers and polyethylene composites on their basis (polyethylene/filler=70/30) due the action mold fungi. chemical composition, dimensional parameters biodegradability have been analyzed as factors exert a considerable impact composite materials biodeterioration. It has found that principal factor determining biodeterioration polyethylene/filler by fungi composition filler and, in turn, its biodegradability. excess holocellulose...

Twelve different natural raw materials were selected as possible fillers for eco-friendly biocomposites. The target was to find the most biodegradable ones. Two mycological tests held: in aqueous and agar media. It found that two showed results. In media, with a high content of water-soluble easy-hydrolysed compounds demostrated intensive biofouling. entire filler exposed biodigestion by fungi. Therefore, multi-compound set macro- microelements more than others.

Recently, there is a great interest in the world to biodegradable materials based on synthetic polymers composition with natural fillers. Highly filled polymer composite various grades of block copolymer ethylene vinyl acetate wood flour were under investigation. Five ethylene-vinyl differing content groups and melt flow index used this work order find best one for highly biocomposites. Wood biocomposites was 50, 60, 70 weight %. The rheological physico-mechanical characteristics resulting studied.

Influence of different environmental factors on the degradation film samples based polylactic acid and low density polyethylene with addition oxidized was studied in this work. Different methods were used to find relationship between ultraviolet, moisture, oxygen. It found that polyethylene, as a model recycled promotes blends.

The influence of physical factors on the destruction biodegradable polymers is also important to evaluate, predicting period their full degradation in environment. One most significant environmental ultraviolet radiation. UV radiation time polylactide was proved by infrared (IR) spectroscopy and differential scanning calorimetry (DSC).
