ABS

ABS (acrylonitrile-butadiene-styrene)

Prop­er­ties

  • Low-cost engi­neer­ing plastic
  • Strong, break-resistant, stiff
  • Easy to machine, cut, paint and glue
  • Out­stand­ing dimen­sional stability
  • Excel­lent aes­thetic qualities

Com­mon uses

  • Machin­ing pre-production prototypes
  • Nat­ural beige and black col­ors are US Food and Drug Administration-compliant for food-processing applications
  • Struc­tural components
  • Sup­port blocks
  • Hous­ings
  • Cov­ers
  • Stor­age bins
