ABS or Acrylonitrile butadiene styrene is a common thermoplastic polymer commonly used for injection molding applications. This engineering plastic is popular due to its low production cost and the ease with which the material is machined by plastic manufacturers. ABS plastic is advantageous in a wide variety of industries. ABS is providing effective solutions to thousands of industries and quality products for millions of different applications. Here is a small selection of well-known products and applications that rely on ABS material: LEGO bricks, small kitchen appliances, keyboard keycaps, automotive components, protective headgear and musical instruments. Just to name a few! All these products and applications are possible due to ABS’s ability to be injection molded and extruded.
