Optical Brightener KSN

Chemical name: 4.4-bis(5-methyl-2-benzoxazolyl)stilbene
Molecular Formula: C30H22N2O2

Properties: It is a benzoxazole compound, its appearance is yellow crystalline powder, melting point 278oC, light blue light, odorless, stable performance.

Features introduced:
1. The weatherability and whiteness are excellent, and it is the first choice of high-grade plastic. The current output is relatively small.
2. The temperature resistance is second only to OB-1, and the current price is higher. Therefore, the market is mostly compounded.

Uses and dosage:
1. It is mainly used for whitening of drawing products, and the amount is between 100g and 200g per ton of material.
2. some engineering plastics, plastic products that require weather resistance and ultra-high brightness can be used instead of OB-1
Packing:

25KG cardboard drum lined with double plastic bags can also be large or small packages according to user requirements.
