A new thermoplastic elastomer (TPE) boasts up to three times the coefficient of friction (COF) of conventional TPE's for both dry and wet applications with reportedly no negative impact on physical and rheological performance. Kraiburg TPE says its so-called Wet Grip technology, offered under the Thermolast W trade name, could boost performance for current elastomer grip applications and potentially open up new markets.
Based on a styrenic block copolymer (SBS) chemistry, the elastomer's wet-grip function is permanent and incorporated throughout the matrix, so that it does not migrate to the surface and dissipate over time. Additionally, Kraiburg TPE says it has no negative impact on processability in multi-component injection molding or extrusion processes. Kraiburg says it has the ability to adapt the technology to its Thermolast branded styrene-ethylene-butylene-styrene (SEBS) elastomer compounds.
