the impact strength to easily pass the 91 cm (36”) drop test. In contrast, the original 100% ICP only passed the drop test from a height of 51 cm (20”). Halsall was able to launch the Pack Away Garage in the period leading up to the peak sales season, selling 80,000 units in Europe in the run up to Christmas with expectations to sell a further 120,000 in the following year.
Beefing up bioplastics The recent growth in bioplastics sales and their use in more demanding applications has created new opportunities for impact modifiers. This is especially the case for PLA, which has many attractive properties, but is also known for its inherent brittleness. Among the first companies to launch impact
Arkema’s new Biostrength 280 maintains clarity in applications requiring toughness and transparency
(-4o F) and improving adhesion. Dry blending 10% to 30%
Vistamaxx with PP at the injection moulding machine provides improved impact strength and eliminates the need for mould modification or an increase in part thickness which would have been costly. Ever Force spent three weeks testing different
concentrations of Vistamaxx in the ICP. A formulation including 15% Vistamaxx was selected as it improved
modifiers for PLA was Arkema with the Biostrength family of products. Its latest addition to the range is Biostrength 280, an acrylic core-shell impact modifier that is designed to maintain clarity in applications that require toughness and high transparency. This FDA- compliant additive has been shown to deliver cost savings by reducing scrap rates resulting from tears and cracks during thermoforming.
