PBAT is a random copolymer known for being flexible and tough. This makes poly butylene adipate-co-terephthalate ideal for combination with other biodegradable polymers that have high elastic modulus and strength, but are very brittle.This allows for the production of blended copolymers that can replace industry-standard plastics with environmentally safe and biodegradable plastics that will harmlessly disappear in a short period of time.
The most important reason for using poly butylene adipate-co-terephthalate as the flexible complement to other polymers is that poly butylene adipate-co-terephthalate will preserve biodegradability, as long as both copolymers can degrade, the blended copolymer will also degrade.

Poly butylene adipate-co-terephthalate is fully biodegradable when composted due to the presence of butylene adipate groups. The high stability and mechanical properties come from the terephthalate portions.Does not degrade in marine and fresh water.

Poly butylene adipate-co-terephthalate is a semi crystalline polymer. The crystallization temperature is usually around 110 ℃, the melting point is about 130 ℃, and the density is between 1.18g/ml and 1.3g/ml. The crystallinity of PBAT is about 30%, and the shore hardness is more than 85. PBAT is a copolymer of aliphatic and aromatic polyesters, 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. LDPE processing equipment can be used for film blowing.
