Note:
  1. Storage:
During transportation and storage, temperature may not exceed 70 oC at any time. Storage time of unopened bags may not surpass 12 months at room temperature (23 oC) .
  1. Shelf-life:
  1. For granules: 12 months from date of loading under proper storage conditions. If customers need to open bags and use them partially, once opened they recommend to seal again properly and use it within 3 months.
  2. For film: we suggest customers use it within 6 months.

  2. in 750kg bag/octabin, liner: PE/Alu (3 )in 1.2t bag/octabin, liner: PE/Alu
 

PBAT Processing Instruction

 
  1. Extruder selection:
Double screw extruder is applicable, length-diameter ratio of film blowing machine should be ≥ 30.
  1. Pre-cleaning:
Washing the machine by using PBAT under temperature 160± 10oC.
  1. Pre-drying:
PBAT don't need pre-drying.(Under the condition package is not damaged). If the package is damaged, then the material need to be dried for 4hours under 65ºC.
  1. Processing data:
If PBAT blending with PLA, we suggest each heating section of extruder heat gradually increase from 155 oC to 190ºC, rotating speed≥250RPM; If PBAT blending with PBS, we suggest each heating section of extruder heat gradually increase from 115 oC to 155ºC, rotating speed≥180RPM; If PBAT blending with starch, we suggest each heating section of extruder heat

gradually increase from 115 oC to 140ºC, rotating speed≥180RPM; it can be adjusted according to actual situation and output.
  1. Residence time:
The residence time for PBAT in the extruder should remains less than 5 minutes. The extruded material will look darker or yellow with long residence time.If the extruded material becomes brittle, it may caused by resin degradation or filler carbonization.
  1. Remark
When MFR is equal, PBAT has good consistency with other biodegradable material, such as PBS, PLA,starch,etc. We suggest adding suitable chain extender and solubilizer when producing PBAT/PLA compound, we suggest adding suitable lubricating agent when producing PBAT/starch or PBAT/inorganic fillers.
