Xaloy PLA Nordson's Xaloy PLA plasticizing system is a screw-and-barrel package that has been specially designed to process polylactic acid (PLA) bioplastics. Barrels are lined with Xaloy X-800, a nickel-based alloy that protects against the corrosive and abrasive effects of PLA compounds, and screws are made from 17-4 PH stainless steel with Xaloy X-183 hardfacing.
What's new? The plasticizing system, which made its debut in June.
Benefits Toughness and flexibility. The line is resistant to corrosion and abrasion and features two screw designs that optimize performance based on the application. For extrusion, the Xaloy Efficient barrier screw with Stratablend II mixer (top) provides chaotic and distributive mixing and homogenized melt temperatures for improved quality and productivity. For injection molding, the Xaloy EasyMelt screw (bottom) can be tailored to a specific PLA resin grade to provide precise temperature control and rapid recovery. When mixing is required, the Xaloy Z-Mixer can be added, and it is particularly valuable for applications that require high clarity.
