TITANIUM DIOXIDE (TIO2) EXTENSION AND UV PROTECTION WITH HYDREX® R
Product for Longer Lasting, More Cost Effective Rubber Formulations
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. This attribute means that replacing expensive titanium dioxide with HYDREX® R makes for a longer lasting, less expensive rubber product. HYDREX® R is also very bright — with a GE brightness greater than 98%. By substituting 10 to 15% of the titanium dioxide with HYDREX® R, the rubber compound stays whiter longer and without compromise to the rubber products mechanical properties.
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. Organic colors (especially red and purple) will also stay brighter and truer longer with HYDREX® R, the UV light reflector and titanium dioxide extender.
