SIPERNAT represents a specific product range of precipitated silica, aluminum and calcium silicates. SIPERNAT 288 is a highly suitable for rubber applications, especially Silicone Rubber e.g. HTV Silicon Rubber. Careful adjustments of parameters such as surface area, particle size, oil absorption capacity and purity (conductivity) result in a product with different properties. SIPERNAT 288 is a fine milled silica with neutral pH value, with relatively high surface area, medium particle size and a very high purity based on selected raw materials. When using SIPERNAT 288, transparent Silicone Rubber products with excellent mechanical properties and a very low yellowish discoloration can be achieved.Information provided by Evonik |
