Acrylonitrile butadiene styrene (ABS)

Acrylonitrile butadiene styrene, or ABS for short, is an impact-resistant thermoplastic with a balanced ratio of strength, rigidity and surface quality. The material combines good mechanical properties with straightforward processing and high dimensional accuracy.

ABS is characterised by high impact resistance, including at lower temperatures. At the same time, the material offers good surface hardness and can be precisely machined, milled and bonded. Its electrical insulating capability supports use in technical applications.

Typical of ABS is the combination of robustness and visual quality. Components can be easily coloured, textured or painted. The material is suitable for series components as well as for functional prototypes.

As an engineering plastic, ABS is positioned in the environment of rubber, foam and plastic solutions and is frequently used where mechanical load-bearing capacity and clean surfaces are required.

Technical classification

ABS is suitable for applications with moderate thermal and chemical loads. Where there are higher requirements for temperature or media resistance, alternative materials are assessed.

Selection and advice on ABS

The selection of ABS is based on the mechanical, thermal and visual requirements of the respective project. Decisive factors are the application environment, the type of load and the desired machining quality. A structured material selection creates planning certainty for design and production.

Typical selection criteria

• Mechanical load and impact stress
• Temperature range in continuous and short-term use
• Contact with media or cleaning agents
• Requirements for surface and dimensional accuracy
• Type of further processing and assembly

ABS is particularly suitable for technical components indoors where a clean surface and reproducible dimensional accuracy are required. Where requirements differ, a cross-material consideration within the portfolio of engineering plastics is recommended.

Project-specific coordination

For specific applications, selection is often carried out in direct comparison with drawings, tolerance specifications and application parameters. Early coordination supports an economical and technically suitable implementation.
