The best plastics for your products

To ensure you receive the best quality possible, we select materials according to the specific requirements of the finished product. This is why we only use top-quality plastic powders from leading suppliers such as Dow Chemical, Ico-Polymers, Poliplast and Matrix.

We use the following plastics in our rotational moulding process

  • Coloured Polyethylene (PE)
  • Uncoloured, food-safe Polyethylene
  • Tested and approved plastics for diesel tanks
  • Polypropylene (PP)
  • Flame-retardant plastic mixtures
  • Special materials offering electrical conductivity
  • Special mixtures, such as with wood

The standard plastics for rotational moulding

The most commonly used plastic in our rotational moulding process is polyethylene (PE). PE is available in various densities from LDPE to HDPE. We also use polypropylene (PP) and polyamides (PA 6, PA 12).

Polyethylene can be given any colour, is extremely resistant to impacts, and also resists many substances and chemicals. If parts are likely to come into contact with diesel, we can also use special plastics that have been tested and approved for this purpose. Petrol tanks must also be fluorinated to make them fuel-proof.

Plastics with special properties in rotational moulding

If your plastic components are destined to come into contact with food, we use uncoloured, food-safe PE. If parts need to be particularly robust or withstand high temperatures, we also use polypropylene (PP). We can also offer a variety of special materials with specific properties such as flame resistance or electrical conductivity.

Plastics for special applications in rotational moulding

Apart from traditional colours (plain, black, white, blue, red, green, yellow, grey or brown), we can also offer custom colours. In addition, we are highly experienced in the use of supplementary natural materials, such as wood particles, ground nutshells, soot and metal particles. Combined with plastic powders, these offer you many different ways to play with surfaces.
