TOPAZ TRILAM UV Spec. A note from manufacturers: In terms of UV stability, the addition level and the type of additives we use to protect the polymers from the harmful action of UV is one of the most important aspects. Our standard rotational moulding grades are fully UV stabilised by adding HALS (hindered amine light stabilizer). The HALS additive works to neutralise the radicals which are generated by sunlight. They are extremely efficient at protecting against the degradation of the polymer caused by UV sunlight radiation. As part of our good manufacturing process, our grades are fully protected against UV degradation therefore they are suitable for long term outdoor use.
TOPAZ TRILAM CONSTRUCTION & MATERIAL Spec. We have the ability to state that we are using the highest quality Superlinear polyethylene available to us. In order to be of any relevance we would have to release potential sensitive information and we do not really want the technical data for our material to be widely available in the market place. We feel that it is more beneficial to leave elements open to interpretation by our competitors and would not be keen to make their lives too easy in establishing where we have reached in terms of material development.
We use the highest quality materials that are available and produce our boats on advanced computer controlled machines that allow us to position the material accurately and glean the maximum possible benefit from the material properties. All the materials being used in rotationally moulded craft have an optimum cook window in which they should be processed to achieve the best out of them. This is particularly important with 3 layer boats where the foam performance drops off rapidly if it is overcooked. You can have the best possible materials but if you do not process them correctly they are useless. Our control systems ensure that the boats we make are of the highest possible quality.
