Product  description:  PBAT  is  biodegradable  polyester  designed for  use  in  film applications.Typical applications:   For packing film applications.

Composition: Poly(Butylene Adipate-Co-Terephthalate).

Form:   PBAT is supplied in pellet form in 25kg bags.

Properties: PBAT has excellent strength and good processability.

Processing   guide

Storage:

Temperatures during transportation and storage should  not exceed  45  ºC.  Keep  resin  in  dry  and  ventilated  stroage  to prevent  moisture. Aviod  contact with  soil, water, sludge  and extremes temperature. The  maximum shelf life is 2 years  in ambient temperature of 23ºC.

Drying:

Pre  drying  of  PBAT  is  recommended  prior  to  get  the  best processing performance.

It is recommended to check the moisture content of the resin prior to processing. If the moisture content of the resin is less than 0.3% pre drying may not be needed.

Typical drying conditions：2 hours at 175ºF (80ºC).

Important:                 PBAT is not suitable for directly blowing film. It’s developed for

blending with other degradable materials, such as PHA and       PLA. Degradable polymers are temperature sensitive. It is         important to make sure the blowing machine is closer to the      lower temperature setting to start with. If the blow part is not      optimized it is recommended to increase the temperature in 5⁰C increments.
