Impact modifier boosts toughness of films

Films are among the most important products to be made of polyolefins. Since they are primarily mass-produced, even slight reductions in the film thickness have the potential to lead to considerable savings. Robert Huber and Jörg Auffermann of BASF explain how Styroflex® 2G 66 SBS block copolymer can be used to increase the puncture resistance and the tear propagation resistance of mLLDPE and PP films. However, this is only the case if the additive is optimally distributed in the polyolefin phase and is present in dispersed form within the nano range.
