Les r\u00e9sultats du test physique effectu\u00e9 sur le mat\u00e9riau en polyur\u00e9thane de Bumper Specialties sont r\u00e9sum\u00e9s dans le tableau ci-dessous. Veuillez noter que ces tests ont \u00e9t\u00e9 r\u00e9alis\u00e9s sur des \u00e9chantillons m\u00e9lang\u00e9s \u00e0 la main et que les valeurs sont des moyennes. Les valeurs obtenues \u00e0 partir d'\u00e9chantillons m\u00e9lang\u00e9s \u00e0 la machine seraient meilleures en raison d'un meilleur m\u00e9lange et d'une r\u00e9duction ou de l'\u00e9limination de l'air pi\u00e9g\u00e9.<\/p>\n\n\n\n
