- How is Cross linking done?
- The process uses high-dose gamma irradiation (5-15mRad) to cause chain scission
- The PE then either rebonds, oxidizes, or cross-links
- Free radical oxidation is prevented using 3 methods

‣
- Packaging
- Good packaging material with low diffusion capability ➔ reduces oxidation
- Vacuum
- Shelf life
