Evonik launches Ultrasil 4000 GR for better grip on mud and snow
Evonik Industries has developed a new, active filler for the tyre industry that significantly improves the traction of winter tyres in snowy and slushy conditions, thereby increasing safety. Ultrasil 4000 GR is the first Low Surface Area (LSA) silica that also offers very good dispersibility. This enables very high filler levels in the tyre tread, further improving traction compared to tyres using conventional silica.
