PEI GF30 (Ultem 2300) vs PPS (unfilled)
Side-by-side chemical composition and mechanical property comparison.
Overview
PEI GF30 (Ultem 2300)
Polyetherimide with 30% glass fiber — Ultem 2300 (SABIC). 2x the stiffness of unfilled PEI (E-Mod 9.5 vs 3.3 GPa) with UTS ~155 MPa. Retains PEI's inherent flame retardance (V-0), chemical resistance, and high Tg (217°C). Reduced elongation (3% vs 60% unfilled). Used for structural aircraft interior brackets, electrical connector housings, under-hood automotive, and medical device components requiring rigidity + flame retardance.
PPS (unfilled)
Polyphenylene Sulfide — semi-crystalline high-performance thermoplastic. Broadest chemical resistance of any engineering plastic — no known solvents below 200°C. Inherently flame-resistant (V-0 without additives, LOI 44%). Very low moisture absorption (<0.02%). Brittle in unfilled form — usually glass-fiber reinforced for structural use. Trade names include Ryton (Solvay), Fortron (Celanese), Torelina (Toray), Durafide (Polyplastics). Used for chemical pump components, filter bags, electrical insulation, and as base resin for GF40 compounds.
