S-EED is a multifunctional additive tailored for processing of polyamides(nylon).it can significantly improve the polyamides’melt processing stability,long term stability and light stability;it has outstanding compatibility and low volatility which can meet the high temperature processing request of polyamide resins;in addition stabilizer S-EED can improve the apparent property of polyamide fiber and nylon injection molded products with smooth surface.

 

More details: 

 

> 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%
