Borealis Borcoat™ HE3450 Black High Density Polyethylene Top Coat for Steel Pipe Coating
Categories:	Polymer; Thermoplastic; Polyethylene (PE); High Density (HDPE)
Material Notes:	Borcoat HE3450 is a black, high-density polyethylene (HDPE) produced with the advanced Borstar technology, providing the material with especially well melt strength and extrudability. Also its mechanical and heat deformation properties as well as ESCR resistance are very good. It contains very well dispersed; fine particle sized carbon black in order to ensure excellent weathering resistance. Borcoat HE3450 is recommended as top-coat in steel pipe coating and is suitable for severe laying conditions even at low and elevated temperatures. With this material, high running speeds and relatively thin layers are obtained. Borcoat HE3450 can be used up to 85°C service temperature of the pipeline with combined with the grafted adhesives Borcoat ME0420 or Borcoat ME0433. Information provided by the Manufacturer.
