Completely biodegradable plastics: Completely biodegradable plastics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polymers Ester, polylactic acid, starch / polyvinyl alcohol, etc. belong to this type of plastic.
Brief description of technical characteristics
1. In the biodegradable formula, all the fully biodegradable components are selected, so that the product can be 100% biodegraded after being used and discarded, and finally carbon dioxide and water are generated;
2, starch, PVA (polyvinyl alcohol), polycaprolactone have good compatibility, and then add a variety of natural additives to make the product's various properties close to or exceed the performance of ordinary plastics;
3. The production of this product has formed a unique process flow during the whole process of mixing, granulation, extrusion, blow molding, etc., which can continuously and stably carry out industrial production.
In the past ten years, plastic has penetrated into all walks of life due to its convenience and has entered millions of households. At the same time, it has caused huge environmental pollution. Various international and domestic environmental protection policies, copyrights, laws and regulations, and environmental protection bills have been introduced. It proves that the demand for biodegradable plastics is gradually entering the normalization and industrialization, and the development of biodegradable plastics is entering a golden period of vigorous development.
      Completely biodegradable plastic PBS is obtained by condensation polymerization of butanediol, succinic acid and other components. Stable performance during use. After use, it can be decomposed into carbon dioxide and water by microorganisms or enzymes in plants and animals under the environment of compost, soil, water and activated sludge. It has good biocompatibility and bioabsorbability. , Environmentally friendly, is a cure for the "white pollution" caused by traditional plastics.
