Polyethylene molding composition for coating steel pipes
Abstract
The invention claims polyethylene molding compound the composition has multi-mode molecular weight distribution and it is especially suitable for producing steel tube is set on the protective coating. The moulding composition in the temperature of 23 centigrade the lower part of the density is 0.94-0.95 g/ cm3 melt flow index mfi 190/5 is 1.2-2.1 dg/min. It comprises 45-55 percent by weight low molecular weight ethylene homopolymer a 30-40 wt% high molecular weight polyethylene and it has 4-8 carbon atoms of olefin copolymer b and 10-20 wt % of ultra-high molecular weight ethylene copolymer c.
