STABILIZED POLYETHYLENE
Polyethylene is often stabilized with the combination of a primary antioxidant (such as a hindered phenol, a hydroxylamine or a lactone) and a secondary antioxidant (such as a phosphonite, a monophosphite, or a diphosphite). The diphosphite additives are not completely compatible with "linear&q...

| description | Polyethylene is often stabilized with the combination of a primary antioxidant (such as a hindered phenol, a hydroxylamine or a lactone) and a secondary antioxidant (such as a phosphonite, a monophosphite, or a diphosphite). The diphosphite additives are not completely compatible with "linear" polyethylene. This results in "blooming" of the diphosphite to the surface of the finished polyethylene part or polyethylene film. The use of a preblend of ethylene vinyl alcohol (EVOH) and diphosphite mitigates this problem.
Le polyéthylène est souvent stabilisé à l'aide d'une combinaison d'un antioxydant primaire (tel qu'un phénol encombré, un hydroxylamine ou une lactone) et d'un antioxydant secondaire (tel qu'un phosphonite, un monophosphite, ou un diphosphite). Les additifs de type diphosphite ne sont pas complètement compatibles avec le polyéthylène "linéaire", ce qui provoque une "efflorescence" du diphosphite à la surface de la pièce en polyéthylène ou du film en polyéthylène fini(e). Pour atténuer ce problème, la présente invention utilise un prémélange d'éthylène-alcool vinylique (EVOH) et de diphosphite. |
