Borealis BorSafe™ ME3420 MDPE Compound for Pressure Pipes (discontinued **)
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Medium Density (MDPE)
Material Notes:	BorSafe™ ME3420 is a bimodal polyethylene compound produced by the advanced Borstar® technology. Well dispersed carbon black gives outstanding UV resistance. Long term stability is ensured by an optimized stabilization system. BorSafe™ ME3420 is classified as an MRS 8.0 material (PE80). Applications: BorSafe™ ME3420 is recommended for pressure pipe systems in the applications field of: drinking water, natural gas, industrial, relining, geothermal collector, and irrigation particularly where flexibility and coil ability is of importance. Thanks to its bimodal structure, it also shows excellent resistance to rapid crack propagation and slow crack growth. Information provided by Borealis AG
