LyondellBasell Akoalit PB 4268 white Polyolefin
Categories: Polymer; Thermoplastic; Polyolefin

Material Notes: Akoalit polybutene-1 homopolymers (PB-H) show improved water quality properties providing the potential to meet stringent future organoleptic requirements. An increased melt flow ratio (MFR) allows up to 50% faster processing due to reduced sensitivity to process-induced orientation. Akoalit PB 4268 white is a premium highly isotactic homo polyolefin manufactured from butene-1 monomer. The product provides excellent long term hydrostatic strength also at elevated temperatures combined with high flexibility. Akoalit PB 4268 complies with requirements specified in ISO 15876, ISO 12230, DIN 16968/DIN 16969 and many other National Standards for PB-1 pipe applications. The grade is typically used for high-performance extrusion into pipe and injection molding into fittings for potable hot and cold water distribution applications where improved organoleptic properties are required. Akoalit PB 4268 is available in white color in pellet form. Akoalit PB 4268 may not be used in the manufacture of pipe applications intended for sale or shipment to North America, without prior written approval by manufacturer for each specific product and application.

Applications: District Heating, Drinking Water Pipe, Industrial, Radiator Connections, Underfloor Heating.
