PC/ABS (Blend) vs TPE-S (SEBS-based)
Side-by-side chemical composition and mechanical property comparison.
Overview
PC/ABS (Blend)
Polycarbonate + ABS blend — one of the most widely used industrial thermoplastic alloys. Combines PC impact strength and heat resistance with ABS processability and lower cost. Better chemical resistance than pure PC. Properties tunable by PC/ABS ratio. Trade names include Bayblend (Covestro), Cycoloy (SABIC), Pulse (Techpolymers). Used for automotive dashboards, laptop/phone housings, power tool casings, and 3D printing (FDM filament).
TPE-S (SEBS-based)
Styrene-ethylene-butylene-styrene (SEBS) based thermoplastic elastomer — the largest and most versatile TPE family. Hardness adjustable from Shore 0A to 100A through compounding with PP, oil, and fillers. Excellent UV/ozone/aging resistance (superior to SBS). Soft, comfortable touch. Non-toxic, meets EN 71 + REACH + FDA. Bonds well to PP and PE in 2K injection molding. Used for soft-touch grips, seals, gaskets, overmolded handles, baby products, medical tubing, cable jacketing, and shoe soles. Not oil-resistant.
