  • How much do you know about ACR processing aids?

    How much do you know about ACR processing aids?

    PVC is extremely sensitive to heat. When the temperature reaches 90 ℃, a slight thermal decomposition reaction begins. When the temperature rises to 120 ℃, the decomposition reaction intensifies. After heating at 150 ℃ for 10 minutes, the PVC resin gradually changes from its original white color ...
