ABS vs PBT GF30
Side-by-side chemical composition and mechanical property comparison.
Overview
ABS
Acrylonitrile Butadiene Styrene — the most widely used amorphous engineering/commodity thermoplastic. Excellent balance of toughness, rigidity, and processability. Good surface finish and paintability. Not UV-stable without additives. Trade names include Novodur (INEOS Styrolution), Terluran (INEOS), Cycolac (SABIC). Used for automotive interior trim, appliance housings (vacuum cleaners, monitors), LEGO bricks, 3D printing filament, and pipe fittings.
PBT GF30
Polybutylene Terephthalate with 30% glass fiber — THE connector and electrical component material. Key advantage over PA6 GF30: near-zero moisture absorption (0.02-0.2%), so mechanical and electrical properties are stable regardless of humidity. Lower UTS than PA6 GF30 but consistent. Trade names include Ultradur B4300 G6 (BASF), Valox 420 (SABIC), Celanex (Celanese), Crastin (DuPont). Used for electrical connectors, relay housings, coil formers, automotive sensors, and any part requiring dimensional stability in humid environments.
