| Borcoat HE3450 is a bimodal, high density polyethylene compound and is coloured black Borcoat HE3450 contains finely dispersed carbon black that helps to impart excellent weathering properties. Applications Borcoat HE3450 is recommended as a top coat for a three layer PE system used in: Steel Pipe Coating Borcoat HE3450 is produced using advanced Borstar® technology that provides the material with good melt strength and extrudability, as well as superior mechanical properties at both low and high design temperatures and very good ESCR. Specifications Borcoat HE3450 is intended to fulfil following National and International standards, when appropriate industrial manufacturing standard procedures are applied and a continuous quality system is implemented and when used in combination with Borcoat TM ME0420 or Borcoat TM ME0433 and a compatible powder epoxy. CAN/CSA-Z245.21 DIN 30670 ISO 21809-1 Gazprom 2-2.3-130-2007 NF A49-710 Special Features Borcoat HE3450 is suitable for severe lay conditions at low or elevated ambient temperatures. High processing speeds and a reduction in layer thickness may be possible under certain conditions. Borcoat HE3450 is intended for design temperature from -45 to +80 °C.&& |
