Evonik offers aliphatic and cycloaliphatic building blocks for the synthesis of weathering stable, high performance elastomers and TPUs.
Silica for plastics processing and properties
Evonik’s silica portfolio enhances the handling, quality and performance of thermoplastics, polymer compounds, and composites. And it offers a wealth of effects for thermoplastically processed products. Used as an additive, silica keeps polymer powders and granulates free flowing and prevents caking, even after long storage. As a reinforcement filler, silica ensures flexibility and tear resistance, surface hardness and scratch resistance of plastics. As a rheology controller, silica adjusts the viscosity of PVC-based plastisols for masterbatches. Special silica grades serve as processing auxiliary and carrier for oils used to create pores or membranes in plastics. Moreover, silica helps to achieve a matt surface effect in components made of thermoplastics
