Thermal Stabilizer for BOPET

Setas thermal stabilizer additive helps to maintain the polymer property profile during processing and improves the polyester thermal stability at elevated use temperatures.
The thermal and thermoxidative degradation rate of PET increases under high shear environments. In many cases, the degradation rate significantly increases due to the joint impacts of the above factors.
