| Evoprene™ Super G compounds are high performance SEBS-based TPE materials. They are formulated with a special resin modifier which increases the size of the end blocks. They are also compounded in a special way to ensure maximum dispersion of the various ingredients. The larger end blocks increase the glass transition temperature (Tg) providing two major practical advantages over regular SEBS-based compounds: improved heat resistance and improved recovery properties. The improved heat resistance raises the service temperature over regular SEBS-based grades by 10-15 deg C (18-25 deg F) and improves injection moulding cycle times by allowing the parts to be demoulded at a higher temperature without distortion. The improved recovery properties, as measured by compression set, provide much better sealing characteristics as explained overleaf. These compounds do need higher processing temperatures for best results. |
