1.Properties:
Appearance:bright yellow crystalline powder Melting point:=295°C Solubility:Insoluble in water,but soluble in high boiling point organic solvents such as phenyl-chloride. Structure:a compound of diphenylethylene bisbenzoxazole type .

2.Applications:
FWA KSN's chemical structure is similar to FWA OB-1's but has much better whitening effects than OB-1 on polyester fibres and plastics,its compatibility with plastics is better than OB-1's too,highly whitening effects is available with only small dosage,KSN has a good resistance to high temperature as well as excellent resistance to light and weather.Applied to whiten polyester,polyamide and polycarylonitrile fibres,used in film,plastic pressing & injection process too.Suitable for whitening high polymers and could be added at any point during synthesizing

3.Directions for use and dosage:
The dosage should be 0.01-0.05% on weight of plastic or polyester granules.Mix the materials thoroughly before shaping of the plastic products or drawing-spinning of polyester fibers.

4.Specifications:

5.Packaging and storing: 10kg carton or 20kg, 25kg carboard drum; or upon clients' request. Stored in cool and dry place.
6.Usage of bleaching agent KSN: for color batch, for color matching, for filling mother stock, for chemical fiber
