Tinuvin 770<\/b><\/strong>\u00a0<\/b><\/strong>Utilisation<\/b><\/strong><\/h2>\n

1. Le Tinuvin 770 est un pi\u00e9geur de radicaux tr\u00e8s efficace qui prot\u00e8ge les polym\u00e8res organiques contre la d\u00e9gradation caus\u00e9e par l'exposition aux rayons ultraviolets.<\/h4>\n

2. Le Tinuvin 770 est largement utilis\u00e9 dans une vari\u00e9t\u00e9 d'applications, notamment le polypropyl\u00e8ne, le polystyr\u00e8ne, les polyur\u00e9thanes, le SAN, l'ASA, les polyamides et les polyac\u00e9tals, le poly\u00e9thyl\u00e8ne haute densit\u00e9, le polyur\u00e9thane, le polystyr\u00e8ne, la r\u00e9sine ABS, etc.<\/h4>\n

3. La grande efficacit\u00e9 du Tinuvin 770 en tant que stabilisateur de lumi\u00e8re le rend parfaitement adapt\u00e9 aux applications dans les sections \u00e9paisses et les films, quelle que soit l'\u00e9paisseur des articles. Combin\u00e9 \u00e0 d'autres produits HALS, le stabilisateur de lumi\u00e8re 770 pr\u00e9sente des effets synergiques importants.<\/h4>\n

4. L'effet de stabilit\u00e9 \u00e0 la lumi\u00e8re de la tinuvine 770 est meilleur que celui des stabilisateurs de lumi\u00e8re couramment utilis\u00e9s. Lorsqu'il est utilis\u00e9 en combinaison avec un antioxydant, il peut am\u00e9liorer la r\u00e9sistance \u00e0 la chaleur, et l'effet synergique avec l'absorbeur de lumi\u00e8re ultraviolette peut encore am\u00e9liorer l'effet de stabilisation de la lumi\u00e8re.<\/h4>\n

La quantit\u00e9 de stabilisateur de lumi\u00e8re Tinuvin 770 ajout\u00e9e :
\nLa quantit\u00e9 d'addition varie entre 0,1% et 0,5%, et la quantit\u00e9 d'addition sp\u00e9cifique est d\u00e9termin\u00e9e en fonction des tests d'application des clients.<\/h4>\n
