Common additives include antioxidants to prevent degradation during moulding and UV stabiliser for outdoor applications.

Pigments or dyestuffs may be added by the supplier or just prior to rotational moulding.

Commonly used additives enhance flow or provide anti-static characteristics.

Other additives add stiffness or reinforcement and for other non-critical applications, a filler may be included to provide bulk and thus reduce the overall material cost. The foregoing provides a basic overview of materials and is in no way exhaustive.

It is vital that each project is taken on its own merit and the appropriate product design, material and process are married together.

Rota Design provides unbiased and educated advice taking the overall objective of the project into account.
