acétate de vinyle (EVA). La réticulation du silane peut être accélérée en plongeant le produit extrudé dans de l'eau chaude ou en l'exposant à la vapeur d'eau. Le produit réticulé présente un allongement à la rupture d'environ 130% et un indice d'oxygène de 29 %. En ce qui concerne certaines applications pratiques, le matériau retarde insuffisamment la combustion, ceci vinyl acetate (EVA). Crosslinking of the silane can be accelerated by dipping the extruded product in hot water or by exposing it to water vapor. The crosslinked product has an elongation at break of about 130% and an oxygen index of 29%. With regard to certain practical applications, the material insufficiently delays combustion, this
