Material Notes:

Borstar ME3440 is a black, bimodal medium density polyethylene compound classified as a MRS 8.0 material (PE80), with optimum balance between flexibility and strength, produced with the advanced Borstar technology. Well dispersed carbon black gives outstanding UV resistance. Long-term stability is ensured by an optimized stabilization system. Borstar ME3440 is recommended for pressure pipe systems in the application fields of drinking water, natural gas, pressure sewerage, relining, sea outfall and industrial, particularly where flexibility and coilability is of importance. It also shows excellent resistance to 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.
