Difference Between DOA And DOS

Cold-resisting plasticizer DOA and DOS are common. Main difference is cold-resisting level.

DOA use into PVC soft products,cold-resisting level from 0 to -25 degree.

DOS use into PVC soft products,cold-resisting level from -26 to -39 degree.

PVC products cold-resisting limit is - 39 degrees Celsius. Need to do modification if lower.

Because of poor compatibility with PVC, two products use general between 5-20 total oil. Easy to run oil if use much.
