Material Notes:
Borstar ME3441 is a yellow, bimodal, cadmium free, medium density polyethylene compound classified as a MRS 8.0 material (PE80) produced with the advanced Borstar technology. It includes a combination of pigments and stabilizers to ensure excellent long-term thermal stability and UV-resistance and resistance to gas condensate. It also shows excellent resistance to rapid crack propagation and slow crack growth.Borstar ME3441 is recommended for pressure pipe systems in the application fields of rapid crack propagation and slow crack growth. Thanks to the structure, it gives outstanding extrudability, compared to conventional PE80 products.Information provided by the Manufacturer.
