PA6 (Nylon 6) vs PPS (unfilled)
Side-by-side chemical composition and mechanical property comparison.
Overview
PA6 (Nylon 6)
Polyamide 6 (Nylon 6) β the most widely used engineering thermoplastic. Excellent combination of mechanical strength, toughness, wear resistance, and chemical resistance. Properties are moisture-sensitive β conditioned (50% RH) values are significantly lower than dry values. Trade names include Ultramid B (BASF), Akulon (DSM), Zytel (DuPont). Used for gears, bearings, bushings, cable ties, structural brackets, and automotive under-hood components.
PPS (unfilled)
Polyphenylene Sulfide β semi-crystalline high-performance thermoplastic. Broadest chemical resistance of any engineering plastic β no known solvents below 200Β°C. Inherently flame-resistant (V-0 without additives, LOI 44%). Very low moisture absorption (<0.02%). Brittle in unfilled form β 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.
