Aliphatic polyester occupies a very important position in the application field of biodegradable materials due to its excellent comprehensive properties. Polyurethane (PLA), polybutylene succinate (PBS), polyhydroxyalkanoate (PHA) , PHBV and other products have also occupied an important share of the biodegradable materials market. However, biodegradable materials have developed rapidly in recent years by virtue of their advantages of not relying on petroleum resources, rich sources, environmental protection, and renewable, and have become a new force that cannot be ignored in biodegradable materials.
 
Composition material and manufacturing equipment of composite degradable material
1. Main materials: starch, polycaprolactone (PCL), polybutylene succinate (PBS), polylactic acid (PLA), ethylene/acrylic acid copolymer (EEA) bentonite, light/oxidative degradation materials, processing Additives etc.
2. Equipment manufacturing: Put the above materials into the special high-speed mixer made by Juli Company in proportion and order under the set temperature and time, and carry out surface treatment and modification technology on the materials, so that the materials are fully mixed and mixed. Compatible; After mixing, plasticizing and granulating with the twin-screw extruder manufactured by Juli, various biodegradable materials are made.
