Poly GlassRub 50 Liquid Rubber is a liquid polyurethane casting rubber that cures to a glass clear (light blue) Shore A 50 rubber. The GlassRub 50 is widely used for making clear molds where it is important to cut the mold. The transparency ensures less chance of damage and better positioning of the part seam because the objects remain visible. The Glassrub is also used to produce clear rubber products, decorative casting products, art, displays or other transparent rubber products.
GlassRub 50 is a medium hard flexible rubber that can easily be colored with the Poly color products. A very small addition of these color pigments based on oil makes it possible to get a colored yet transparent material.
