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 4984:2016 for 'Polyethytene pipes for Water Supply - Specification' when incorporated with adequate quantity of carbon black as specified in clause 5.3 of IS: 4984: 2016. It will also meet the requirements of the designation PE EL C45T006 mentioned in the clause 4.2 of IS 7328: 1992.

Pipe made from Relene 45GP004 grade passes the Internal Pressure Creep Rupture Test when tested with 4.5 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 4984:2016, 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.
