| PEE / PH or gas injected is a new method to make a dielectric. Unicavi has been the first italian manufacturer to adopt and develop this new extrusion method that is also called PHYSICAL PROCESS. The most important difference between this new method and the traditional one called chemical (PEE) regards the different extrusion process. The PEE process use a chemical additive whereas the PHYSICAL process uses an inert gas ( Nitrogen). By using the traditional method we get a dielectric provided with a low meccanic robustness and a with a limited time stabilily of the electrical characteristics. |
