?PLA Degradable Sheet/Rolls Sheet Extrusion Production Line Equipment
Lactic acid, the main component of PLA, is mostly prepared by fermentation of starch, and the process and technology are mature. It is a colorless, smooth hard plastic with high strength and high modulus. Its mechanical properties are similar to PS, and its tensile and flexural modulus are higher than HDPE, but its toughness is poor. It is suitable for various processing processes such as injection molding, blow molding, thermoforming, extrusion, casting, melt spinning and electrospinning. Mainly used for packaging and fibers. also be used as engineering plastics in machinery, chemical and other equipment, and is widely used in drainage boards.
?PBAT Degradable Sheet/Rolls Sheet Extrusion Production Line Equipment
PBAT is an aliphatic-aromatic copolyester with low crystallization rate, flexible aliphatic chain and rigid aromatic ring in the molecular chain, excellent mechanical properties and can be naturally degraded. Widely used in plastic film, film bag packaging and other fields, it is one of the fastest growing and most widely used degradable plastic varieties.
?PBS Degradable Sheet/Rolls Sheet Extrusion Production Line Equipment
PBS (direct esterification method) has a high melting point, can withstand a high temperature of 100 ° C with a little modification, has excellent degradation performance, and can be biodegraded under natural conditions. Moreover, it is easy to process, has good heat resistance, excellent comprehensive mechanical properties, and has a wide range of uses. In the medical field (such as artificial cartilage, sutures, stents), etc.
