PBAT name is butylene terephthalate has both the characteristics of PBA and PBT. It has good ductility, elongation at break, heat resistance and impact resistance, and has excellent biodegradability. It is one of the most active biodegradable plastics researches and one of the best degradable materials in the market.
Characteristics: PBAT is a semi-crystalline polymer. The crystallization temperature is usually around 110 ℃, and the melting point is around 130 ℃. The density is between 1.18g / ml and 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 polyester and the good mechanical properties of aromatic polyester. The processing performance of PBAT is very similar to LDPE, and the film can be blown with LDPE processing equipment.
