Thermoplastic Elastomer SIS HEXAS EL-9163

Product Introduction

Like all thermoplastic elastomers, SBS and SIS are less resilient than permanently interlinked vulcanized rubber, and they do not recover as efficiently from deformation. Also, they soften and flow as the glass-transition temperature (the temperature below which the molecules are locked in a rigid, glassy state) of polystyrene (about 100 celcius degree) is approached, and they are completely dissolved (and not merely softened) by suitable liquids. Nevertheless, SBS and SIS are easily processed and reprocessed, owing to the thermoplastic properties of polystyrene, and they are remarkably strong at room temperature. They are frequently used for injection-molded parts, as hot-melt adhesives (especially in shoes), and as an additive to improve the properties of bitumen.

Application

Pressure sensitive adhesives, Sealants, Road marking paint, Bitumen modification, Waterproof membrane adhesive，Hygiene adhesive.
