PC/ABS (Blend) vs TPU (Thermoplastic Polyurethane)
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).
TPU (Thermoplastic Polyurethane)
Thermoplastic polyurethane elastomer — bridges the gap between rubber and rigid plastics. Exceptional abrasion resistance, high elongation (300-700%), and good oil/grease resistance. Available in wide hardness range (60 Shore A to 74 Shore D). Ester-based: better oil resistance. Ether-based: better hydrolysis/microbial resistance. Major trade names: Elastollan (BASF), Desmopan/Texin (Covestro), Estane (Lubrizol). Used for seals, hoses, cable jackets, shoe soles, phone cases, wheels/rollers, and 3D printing filament.
