Letter from the ARMO Chair

by Martin Spencer, ARMO Chair


Welcome to our first Newsletter of 2018!

The hot topic this year at meetings and conferences around the Rotomoulding world is Automation. There is interest in this topic for several reasons. In many areas of the world we are experiencing times of high employment so finding and retaining good employees is becoming more and more difficult. So different levels of automation are being considered and introduced to make the employees be more productive. Well-engineered machines and robots can operate 24/7 without refreshment breaks or annual holidays, both in part moulding and finishing operations. READ MORE

Colours in Rotomoulding

Rotomoulding is a fantastic process that is versatile, flexible, and open to design. By using colours, you can differentiate your products and make them unique.

by Angélique Brocatus-Kooijmans, Business Development Manager Powders, A. Schulman


Colours are not only used as visual appreciation but can be used for safety reasons as well, think about road bollards.

To produce a colour, different methods in the industry can be used. You can use dryblending, by adding a pigment to your natural polymer, via a low speed or high speed blender. Or you can make a fully compounded colour via an extrusion process. READ MORE


Polypropylene – The Quasi Engineering Material

by Ravi Mehra, PSD Rotoworx P/L & 4Roto LLC


Breaking Out of the Polyethylene Dependancy

As far back as the 1980’s there has been a very clear desire from rotational moulders and designers: “We need more variety of resins to work with, other than “Polyethylenes”. As time has gone by the request for more variety of resins has continued. The intensity of this message has not waned; the industry just kept hoping and asking for more.

Over the years resin suppliers have made presentations at conferences introducing different materials. Some of them were modified grades of Polyethylene, formulated to address a specific need, but there were other non-Polyethylene resins promoted as well. These included: Nylon 6, Nylon 11 & 12, PVDF, Polycarbonate, Polyurethane, Polybutylene, and Polypropylene, just to name a few. Why then does rotomoulding continue to be defined by Polyethylenes? Not because that is the only material available, but because it is the material that is most widely used.
