Why is pentane used as blowing agent? Pentane–blown foams have another advantage: better dimensional stability due to the fact that pentane does not condense as much as HCFC-141b at temperatures normally experienced by the foam in use. The condensation of HCFC-141b causes the cells to shrink and expand on a cyclical basis, reducing dimensional stability.”

Blowing agents are used to decrease the density of the polymer, typically by 40–60% with loading levels of 0.5–20.5% by weight on the amount of polymer.

PBAT has excellent mechanical performance, almost same as PP and ABS, good heat resistance and outstanding process ability allows it to be variously processed on conventional blown film plants.
Our PBAT is completely degradable according to various international standards and regulations like European standard EN 13432 and American Standard ASTM 6400, which will be eventually biodegraded to carbon dioxide, water and biomass when metabolized in the soil or degradable under standard conditions. Our resins are also certified by Ok Compost, BPI, ABAM, JBPA, FDA, EU Food Contact regulations, etc.

Temperatures during transportation and storage should not exceed 70 oC. Keep resin in dry and ventilated warehouse to prevent moisture. Avoid contacting with soil, water and sludge, and no exposure to direct sunlight and extreme temperature. The maximum shelf life is 2 years in ambient temperature of 23oC if the package has been tightly sealed.
DRYING:
It is recommended to pre-dry the material prior to getting the best processing performance. If the moisture of the resin isless than 0.05% pre-drying may not be needed.
Typical drying conditions:2 hours at 80oC (175oF).
PROCESSING GUIDE:
TH801T is not suitable for direct film blowing, it is suggested to add slip additive like SiO2 or CaCO3, it can also be blended with starch, PLA, PHA, cellulous etc. Normally the extrusion temperature is 140oC -170oC which depends on formula and processing machine, it is important to make sure the blowing machine starts from the lowest temperature. If the blowing performance is not optimized it is recommended to increase the temperature by 5o C.
