Retain the color in your white rubber compounds. With a silicate from Huber Engineered Materials.
Huber Engineered Materials has the answer to this challenge: Hydrex® R.
Hydrex R is a sodium-magnesium-aluminosilicate that acts as a UV light reflector, contrasted with titanium dioxide (TiO2), which serves as a UV light absorber.
Without Hydrex R, the absorption of light energy creates free radicals in the compound that ultimately degrade the polymer system. The addition of Hydrex R mitigates the effect of exposure to sunlight and other UV sources.
Hydrex R not only increases the UV resistance of rubber compounds, it also lowers formulation costs. Typically, Hydrex R costs significantly less than TiO2. Hydrex R is also very bright — its GE brightness is over 98. By substituting 10 to 15% of the titanium dioxide with Hydrex R, the compound stays whiter longer, and will not compromise mechanical properties.
Organic colors (especially red and purple) will also stay brighter and truer longer with Hydrex R, the UV light reflector.
