Q: Is it possible to apply the rubber antioxidant DPPD (S grade) to polyolefin heat shrinkable tubing? What is the ratio of addition?
A: The content of the relevant antioxidant is 0.5%-1.5% of the resin content, or about 1 part to 3 parts. It is not recommended to increase the content of the antioxidant too high, which will increase the cost and affect its mechanical properties. It depends on the specific Formula to match and use.
