Frequently Asked Questions
What are ABS's main limitations?
Poor UV resistance (yellows and embrittles outdoors), low chemical resistance to solvents and fuels, and limited heat resistance (HDT 85°C). For outdoor applications, use ASA (acrylic-styrene-acrylonitrile) which has 10x better UV stability. For chemical exposure, upgrade to PC/ABS or PPO/PS.
