(3) Processing Notes:
① Normally need not drying, if absorbed moisture, pre-drying the particles for 2 to 4 hours at 80℃.
② Cleaning the screw and die with PP or PE before and after processing.
③ The gate and runner can be recycled, but less than 15%.
④ PE/EVA base color masterbatch is better for coloring.
