GM5049B is a black high molecular weight High Density Polyethylene. It is a high performance resin for use in pressure pipes where service life to 50 years is required. GM5049B offers a balance of excellent processing characteristics along with outstanding toughness, chemical resistance and environment stress crack resistance. GM5049B will also provide excellent resistance to the effects of Ultra-Violet light exposure in outdoor applications.

GM5049B has been designed for extrusion into a full range of pipe and fitting sizes, where High Density, PE 100 Type resins are required. GM5049B is suitable for use in the transport of a wide range of fluids for industrial, rural and mining applications, including potable water. Suitability for use in any application should be determined by appropriate performance testing.

GM5049B has been designed to meet the requirements for PE 100 Type compounds and has been accepted by Australasian Polyolefine Pipeline Systems Inc. as meeting AS/NZS 4131:1997 and is intended to be used in pipes conforming to AS/NZS 4130. The material does not comply with clause 8. of AS/NZS 4131:1997 in that the long-term hydrostatic strength at 50°C has not been determined. It does comply in full with draft standard AS/NZS4131 (draft 1999). GM5049B is suitable for food contact applications and conforms to the requirements of AS2070.
