Biodegradable Filler Masterbatch

Biodegradable plastics can be divided into completely biodegradable plastics and destructive biodegradable plastics. Talc powder manufacturers

Destructive biodegradable plastics currently mainly include starch-modified (or filled) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, etc.

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 polyesters, polylactic acid , starch/polyvinyl alcohol, etc. belong to this type of plastic.

Biodegradable polymer materials refer to a class of functional polymer materials that can be degraded or enzymatically hydrolyzed in the body, and the resulting small molecular substances are absorbed by the body and excreted from the body. At present, the biodegradable polymers that have been researched and developed mainly include three categories: natural polymers, microbial synthetic polymers and chemically synthesized polymers. Among them, natural degradable polymers include starch, cellulose, polysaccharide, chitin, chitosan and its derivatives; degradable polymers synthesized by microorganisms include polylactic acid (PLA), polyhydroxyalkyl alcohol ester, poly( Synthetic degradable polymers include polyvinyl alcohol (PVA), polylactic acid (PLA), polyα-hydroxyesters, polycaprolactone (PCL), etc.

Biodegradable plastics based on natural substances such as starch currently mainly include the following products: polylactic acid (PLA), polyhydroxyalkanoate (PHA), starch plastics, bioengineering plastics, bio-universal plastics (polyolefin and polychlorinated vinyl)
