TPR Compounds

SBS/SEBS-based rubber elasticity with thermoplastic processability

Product Overview

Thermoplastic Rubber (TPR) compounds are SBS/SEBS-based formulations offering rubber-like elasticity with full thermoplastic processability. Used where a tactile rubber-like surface feel combined with precise dimensional accuracy is required. TPR grades are widely favored in the footwear industry for outsoles and insoles, where the combination of rebound resilience, abrasion resistance, and the ability to achieve fine surface detail in injection moulding gives them a decisive advantage over traditional vulcanized rubber. The SEBS-based variants deliver superior UV and thermal stability compared to SBS grades, making them suitable for outdoor and high-temperature applications. Our TPR grades adhere well to PP and ABS substrates in two-shot moulding and over-moulding processes, enabling the production of ergonomic soft-grip handles, toothbrush bodies, packaging seals, and baby product components where safe material selection is paramount. All grades are formulated to be free of phthalates, heavy metals, and other restricted substances, complying with REACH and RoHS directives.
