Various stearates, LIGA CALCIUMSTEARAT 800, LIGA ZINK-STEARAT 101/6, LIGA MAGNESIUMSTEARAT techn. or LIGASTAR AL D2 and TR are used in olyamides, polycarbonates and acrylic resins. Which additive is the right one depends on the processing conditions and its solubility in the respective plastic. In general, free flowing properties and workability of the components are improved. LIGASTAR AL TR is particularly suitable for transparent applications in acrylic glass. LIGASTAR AL D2 is suitable for colour stabilization during melt-extrusion of polyester fibres. LIGA CALCIUMSTEARAT 800, LIGA ZINKSTEARAT 101/6, LIGA MAGNESIUMSTEARAT techn. or LIGASTAR AL D2 are added to hot-melt adhesive formulations during pulverization and improve the lubricating and separating properties as well as free flowing ability of the initial products. LIGA NATRIUMSTEARAT and LIGA KALIUMSTEARAT have proved useful as effective emulsifiers for emulsion polymerization.
