RELENE? 45GP004

High Density Polyethylene

Reliance Industries Limited

产品说明：

Relene 45GP004 ( PE:80 ) is a natural coloured grade for pipe extrusion.

It possesses bimodal molecular weight distribution, which improves processability. This grade meets the MFI, Density Hydrostatic strength requirements of material grade PE:80 as per IS 4984. When incorporated with adequate quantity of carbon black as specified in clause 5.2.3 of IS: 4984, Pipes will meet PE:80 requirements .

Pipe made from Relene 45GP004 grade passes the Internal Pressure Creep Rupture Test when tested with 4.6 MPa induced stress at 80°C for 165 hrs and with 4.9 MPa induced stress at 80°C for 48 hrs as per clause 8.1 of IS 4984, thereby meeting the requirement of PE:80 grade.

This grade conforms to ISO 4427 specification shown below and has been certified for MRS 8 MPa as per ISO 9080.
