EOS at this year’s EuroMold in Frankfurt, Germany launched the PA 1102 black material. PA 1102 black is a material made from renewable resources. It is a mass-coloured Polyamide 11 material for the manufacturing of deep black, highly resilient parts. Due to its colour, the parts made based on this material are resistant to dirt or discolouration even under most extreme conditions. PA 1102 black has a high flexibility, bendability and impact resistance so that the parts will not split even under excessive load conditions. The materials excellent mechanical properties make the material a perfect fit for serial parts, highly stressed functional models as well as design prototypes.

Properties

  • mass-colored black
  • high elongation at break
  • high impact resistance
  • elasticity
  • excellent resistance to chemicals, especially hydrocarbons, aldehydes, ketones, mineral bases and salts, alcohols, fuels, detergents, oils and fats

Applications

  • mechanically loaded functional prototypes and series parts with long-term moving elements (e.g. hinges)
  • in the automotive industry, it is mainly used for interior components for crash relevant parts (PA 1101 components do not splinter)
  • well suited for abrasively stressed visible parts
  • especially suited for small to medium sized parts, thin walls and lattice structures

During material development EOS has closely cooperated with pilot customers. One of them is UK-based company 3T RPD, who, after a number of material tests, are highly satisfied: “The addition of PA 1102 black to our portfolio will be relevant for a wide range of customers and specifically those looking for a ‘true black’ without the inconsistency or bloom that has been a feature of parts produced with filled powders or surface coloured parts.  It will offer an alternative to those customers wanting serial production parts to be used in environments where enhanced mechanical properties are valued such as parts that are regularly handled or knocked” says Dr. Mark Beard, Head of R&D at 3T RPD Ltd.

Another US-based pilot customer praises the excellent serial capabilities of the PA 1102 black material: Mike Schuch, Head of Mechanical Engineering & Machine Shop at Accurate Technologies Inc. sums up the testing results as follows: “In 2014, Accurate Technologies Inc. joined with EOS to help develop and refine the PA 1102 black Nylon 11 material. This material is Accurate’s primary material and the basis for several ATI products, the first of which was the ’CANary Interface Module’. We’ve been very happy with the results. The PA 1102 black material gives us the ability to produce innovative products that are enclosed in equally innovative designs that are custom fitted to our products without compromising strength, durability and good looks. We look forward to releasing many more products in the future with this very effective combination.”
