Brief Intorduction:
PBAT degradable blown film material, PBAT starch degradable biomaterial, special degradable material for film
PBAT is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. It has both the characteristics of PBA and PBT, and has good ductility and elongation at break. Good heat resistance and impact performance; in addition, it also has excellent biodegradability, which is very popular in the research of biodegradable plastics and one of the best degradable materials in the market.
PBAT is a semi-crystalline polymer, usually the crystallization temperature is around 110 °C, the melting point is around 130 °C, and the density is between 1.18g/ml~1.3g/ml. The crystallinity of PBAT is about 30%, and the Shore hardness is above 85. PBAT is a copolymer of aliphatic and aromatic, which combines the excellent degradation properties of aliphatic polyesters and the good mechanical properties of aromatic polyesters. The processing performance of PBAT is very similar to that of LDPE, and the film can be blown with the processing equipment of LDPE.
Main applicaitons:
PABT degradable materials are suitable for injection molding, film blowing, extrusion and other processes, and are widely used in plastic cups, flower pots, plastic cutlery and forks, and four-compartment lunch boxes. The manufactured product films can be used for degradable shopping bags, agricultural mulching films, etc.
