Electronics and Telecommunications
The innovative strength of Evonik is indispensable in the electronics and telecommunications sectors. Evonik Industries markets flame retardants that provide reliable fire protection to computer housings that are exposed to heat.
Evonik also has the optimal solution for moisture: if water gets into electrical cables, polymers immediately swell to prevent it from advancing any further. Cavities are promptly sealed and damage is restricted to a small area. In this way, all key technical and economic requirements of rapidly advancing developments in the cable industry are satisfied.
Evonik is also the world's biggest supplier of pyrogenic metal oxides, with proven success in supplying the semiconductor industry with abrasive particles for chemical-mechanical polishing (CMP) - a technology that is used in the manufacture of integrated circuits.
In case of fire, cables should not burn or smolder and should definitely not emit toxic gases. Evonik supplies components for cable sheathing that addresses these requirements. In addition, fumed silicas are used as thixotropic agents in cable gels to protect the sensitive glass fibers in fiber optic cables.
Toners for today's laser printers are high-tech products. High resolutions are possible only with the use of specially treated fumed silicas from Evonik. So that the ink in inkjet printers doesn't bleed and so that it dries quickly, the paper is coated with silanes and silicas.
