Abstract
A plastic pipe is made of a cross-linked polyolefin to be utilized in, but not limited to, potable water applications. Certain antioxidants and stabilizers are added to a process for producing the plastic pipe. The added antioxidants and stabilizers remain as key components in the final plastic pipes, providing superior long term stability and resistance to oxidative degradation, the latter being caused by but not limited to, chlorinated water environments. At least a primary stabilizer is used in the material.
