  • Preparing glass flake reinforced reaction injection molded polymers
    Patent number: 4564491
    Abstract: The physical properties of reaction injection molded (RIM) polymeric articles are substantially improved by internally reinforcing them with flake glass filler particles. The flake glass is incorporated in the liquid chemical polymer precursors, and is co-injected with them into the mold. The flow of the liquids in the mold orients the glass flake to provide maximum improvement in physical properties in the hardened polymerized article. Molding with glass flake filler also substantially alleviates problems of surface waviness in RIM panels.
