| Hifax CA 721 GW is a flexible polypropylene resin used by our customers for waterproofing applications. It is manufactured using the LyondellBasell’s proprietary Catalloy process technology. Hifax CA 721 GW membranes can be produced on slot die extruders, circular die (Blown film) extruders and on most of the calendering units. Hifax CA 721 GW is available in natural pellet form, and is UV light stabilised. Our customers use Hifax CA 721 GW to produce flexible membrane, fish pond liner, snow lagoon membrane, tunnel lining, water reservoir liner, floating cover, soil and waste sheet and flexible profiles. Hifax CA 721 GW is not intended for medical and pharmaceutical applications.&& |
