PEEK GF30 vs TPE-S (SEBS-based): 0% composition overlap. Significantly different materials serving different application areas.
PEEK GF30 vs TPE-S (SEBS-based)
Side-by-side chemical composition and mechanical property comparison.
Overview
PEEK GF30
PEEK with 30% short glass fiber reinforcement. Dramatically increased stiffness (E-Mod 11 GPa vs 4.1 unfilled) and strength (UTS 160 vs 100 MPa) with reduced elongation and creep. Maintains PEEK's chemical resistance and high-temp capability (continuous 250°C). Trade names: Victrex 450GL30, TECAPEEK GF30 (Ensinger), KetaSpire GF30 (Solvay). Used for structural brackets, pump housings, valve seats, bearing cages, and semiconductor wafer handling where higher stiffness than unfilled PEEK is needed.
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.
