HDPE Granules / GP20 Granules
GP20 is a blue, reprocessed high-density polyethylene compound supplied by Grano Pipe Industries for pipe manufacturing. Its technical data sheet records a melt flow index of 0.3 g/10 min at 190°C under a 5 kg load and a tensile strength at yield of 21–24 MPa.
Supplied in 25 kg net moisture-proof bags, GP20 allows processors to review defined typical properties before selecting material for their production requirements. Share your intended application, quantity and pipe sizes with our team for further information.
GP20 Granules provide blue HDPE feedstock for pipe production. HDPE granules are melted and shaped during extrusion; selecting a suitable compound is part of achieving the desired processing and finished-product performance.
The supplied GP20 technical data sheet lists density, melt flow index, tensile strength, elongation, hardness, ash and moisture content. These are typical material values; selection should also consider the processing equipment, finished-pipe design and intended service conditions.
Packaging: 25 kg net moisture-proof poly bags.
Storage and handling: Keep the material in its original packaging in a shaded area, away from sunlight and moisture, at an ambient temperature not exceeding 50°C. The data sheet recommends use within 12 months of production and drying before processing.
