Potters Industries has just completed a study of the benefits of using engineered glass microsphere particles. According to William Shaker, Market Development Manager of Polymer Additives at Potters Industries, "One of the major benefits of adding solid glass spheres to resin formulations is reduced manufacturing costs. By using Spheriglass solid glass microspheres as resin extenders, they can realise substantial cost savings while gaining enhanced physical properties." Spheriglass spheres are performance modifiers engineered to increase the strength of plastics. High loadings of glass spheres add significantly to the dimensional stability of the finished product by reducing shrinkage & improving part flatness, e.g. data show that shrinkage of unfilled or glass fiber filled nylon 66 can be cut by 70-80% when 30% glass spheres are used.
