HBM5520
HBM5520 is a high density polyethylene with medium molecular weight. It appears as pellet form. It contains no slip agent, antiblock and processing aid but it contains antioxidant. This grade offer excellent combination of toughness, stress cracking resistance, good mechanical properties and good process ability. HBM5520 has been manufactured under Basell license.

1.Typical values: these are not to be construed as specifications.
2.The density parameter was determined on compression-molded specimens, which were prepared in accordance with procedure C of ASTM D4703, Annex A1.
3.Properties are based on compression-molded specimens, which were prepared in accordance with procedure B of ASTM D4703, Annex A1, using 100% HBM5520 resin.
4.Please note that, these processing conditions are recommended by manufacturer only for 100% HBM5520 resin (not in the case of blending with any other compatible material), therefore because of the many particular factors which are outside our current knowledge and control and may affect the use of product, no warranty is given for the foregoing data. Moreover, the specific recommendations for resin type and processing conditions can only be made when the end use, required properties and fabrication equipment are known.
