Patent

CA 2500204

The invention concerns a method whereby a foam layer is formed by rotational moulding in a step which consists in heating the foaming polymer which is interrupted before foaming temperature is reached, the process being based on the thermal inertia of the system also including the mould (1) and the layers already placed to complete the heating, without, however its reaching an intensity which would provoke haphazard foaming. The foam layer is uniform and adhesive. The dense layers enclosing the foam layer may be different.

Une couche de mousse est formée en rotomoulage par une étape de chauffage du polymère moussant qui est interrompue avant que la température de moussage ne soit atteinte : on se fie à l'inertie thermique du système composé aussi du moule (1) et des couches déjà placées pour compléter le chauffage, sans qu'il atteigne toutefois une intensité provoquant un moussage désordonné. La couche en mousse est régulière et adhérente. Les couches denses entourant la couche en mousse peuvent être différentes.
