Thermoplastic elastomer based on styrene–ethylene/propylene (SEP) triblock copolymer architecture.
Excellent melt processability via extrusion, injection molding, and blow molding without vulcanization.
Superior balance of elasticity, tensile strength, and low-temperature flexibility down to –40 °C.
Good resistance to ozone, UV radiation, and polar solvents compared to conventional SBCs.
Compatible with polypropylene (PP) and polyethylene (PE), enabling robust thermoplastic vulcanizate (TPV)-like blends.
Automotive interior trim components including soft-touch door panels and instrument cluster surrounds.
Sealing systems for HVAC ducts and fluid handling gaskets requiring dynamic compression set resistance.
Consumer electronics housings and protective overmolded grips for power tools and appliances.
Medical device tubing and non-sterile wearable component housings where biocompatibility support is available upon request.
High-performance sporting goods grips, bicycle handlebar wraps, and ergonomic tool handles.
