(FR) MOUSSE DE POLYÉTHYLÈNE SOUFFLÉE PHYSIQUEMENT
Abstract: front page image
(EN)The invention is directed to a masterbatch comprising a nucleating organic compound which, on changing to the solid phase, forms crystals and which in its melt phase is soluble in the molten polyethylene and physically blown polyethylene foam polyethylene. The ingredients of this masterbatch are applied as a nucleating agent masterbatch during the production of polyethylene foam.
(FR)La présente invention concerne un mélange maître comprenant un composé organique de nucléation qui, en se changeant en phase solide, forme des cristaux et qui, dans sa phase fondue, est soluble dans le polyéthylène fondu. L'invention concerne également une mousse de polyéthylène soufflée physiquement. Les ingrédients de ce mélange maître sont appliqués en tant que mélange maître d’agents de nucléation pendant la production de la mousse de polyéthylène.
