ABS properties
ABS is a common, economical thermoplastic with a good balance of toughness, rigidity, and surface finish. It is easy to machine, mold, and 3D print, making it ubiquitous in consumer products, housings, and prototypes.

Typical uses
ABS is used for housings, enclosures, automotive trim, toys, pipe fittings, and 3D-printed prototypes. Its toughness, easy processing, and good finish make it a default for molded consumer parts, and it glues and paints readily.
How it compares
ABS is tougher and more impact resistant than PVC and easier to finish, but softer and less heat and chemical resistant than engineering plastics like nylon or polycarbonate. It is the economical general-purpose choice for housings and prototypes.
FAQ
What is ABS plastic used for?
Housings, enclosures, automotive trim, toys, and 3D-printed prototypes, where toughness, easy processing, and a good finish are wanted at low cost.
Can ABS be glued?
Yes, easily, with solvent cements or common adhesives, and it also paints well, which adds to its popularity for consumer parts.
Is ABS heat resistant?
Only moderately, up to about 80 C in continuous use. For higher temperatures, engineering plastics like nylon or polycarbonate are better.
