Our range of EMA technical springs is made from high-performance plastic materials, designed for demanding applications in sectors such as automotive, electronics, chemical, machinery, construction, and industrial interiors. They allow a significant weight reduction compared to metal, while maintaining strength, durability, and safety where the application permits.

Each material offers specific performance in thermal, mechanical, and chemical resistance. Below is a practical summary to help you choose the most suitable one:

  • PC (Polycarbonate): Up to 120 °C · Very good mechanical properties · Limited chemical resistance
  • POM (Acetal): Up to 100 °C · Excellent mechanical properties · Good chemical resistance
  • PEEK: Up to 250 °C · Outstanding mechanical properties · Excellent chemical resistance
  • PEI: Up to 170 °C · High mechanical properties · Good chemical resistance
  • PPSU: Up to 180 °C · Very good mechanical properties · Excellent chemical resistance
