Sanyo Chemical's innovative resin modifier improves wetting of polyolefins

Japanese company Sanyo Chemical Industries Ltd reports that its researchers have developed a resin modifier that can increase the surface hydrophilicity of polyolefins, which are highly hydrophobic by nature. Dubbed MEL-AQUA 350L and currently at the preproduction stage, the additive can improve the coating ability and adhesiveness of moulded polyolefin parts without the need for surface treatments such as corona discharge, the company says.
