Applications and characteristics:

 

Light stabilizer S-EED improve the melt processing operations of polyamides;

Light stabilizer S-EED enhance long-term heat and photo-stability;

Light stabilizer S-EED increase the polyamides affinity for acid dyes both due to basic groups and π-interactions,Light stabilizer S-EED  enable economical,ecological and deeper topical dyeing;

polyamide materials which contains Light stabilizer S-EED can be used in the moulding of nylon articles and for production of nylon 6 and nylon 66 fibers for carpet manufacture; Nylostab S-EED is effectively combined with Diphosphonite antioxidant(CAS NO.:119345-01-and Hostavin VSU(23949-66-8) to minimise discoloration and to enhance UV stability of polyamides, respectively.

light stabilizer S-EED is not approved for plastics in food-contact applications;

Recommended dosage: 0.2%~2%
