PC/ABS (Blend) vs PP (Polypropylene)
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).
PP (Polypropylene)
Polypropylene is the most produced plastic globally by volume. Semi-crystalline thermoplastic with excellent chemical resistance, low density (0.90–0.91 g/cm³ — lightest engineering plastic, floats in water), good fatigue resistance (living hinges) and low cost. Available as homopolymer (higher stiffness) and copolymer (better impact). Trade names: Moplen (LyondellBasell), Sabic PP (SABIC), Borealis PP. Used for packaging, automotive bumpers/interiors, medical devices, piping, hinges, containers, textiles (nonwoven) and household goods.
