Two new PP grades for LyondellBasell

4 September 2015

Plastics, chemical and refining company LyondellBasell has added the Moplen grade HP742U and HP743V to its range of polypropylene (PP) products.

The new, high-flow, nucleated homopolymer grades produced by its Geelong-based polypropylene plant are used for high-speed thin-walled injection moulding (TWIM) of housewares and media boxes. In this application, rapid cycle times are required, together with consistent performance, low organoleptic properties (odour and taint), and a balanced level of mechanical properties.

Business manager Robert Moran said HP742U and HP743V were “game changers” as customers needed a combination of high flowability, stiffness and organoleptic performance.

“Customers report that both products quickly fill the mould due to a high melt flow rate of 90g/10 min and 120g/10 min respectively and offer the potential for down-gauging and a reduction in cycle time and energy.”

LyondellBasell also has PP random copolymers with high flowability, transparency and impact resistance, as well as PP impact copolymers that offer high-impact resistance at sub-zero temperatures.
