PEEK GF30 vs POM-H (Acetal Homopolymer)
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.
POM-H (Acetal Homopolymer)
Polyoxymethylene Homopolymer — slightly stronger and stiffer than POM-C copolymer but with centerline porosity in stock shapes and lower resistance to hot water/alkalis. Trade names include Delrin (DuPont/DuPont de Nemours) and Tenac (Asahi Kasei). Used for gears, cams, springs, clips, fuel system components, and precision-machined parts where maximum stiffness is needed.
