Specification:
1) Appearance of light yellow-green powder
2) Purity (>99.0%)
3) Melting point 230-232 C
4) Particle fineness (> 4um particle number) less than 3
Application:
Fluorescent Brightener Agent ER-1 belongs to stilbene compounds and is insoluble in water. It has good solubility in most organic solvents and is stable to cationic softener. It can be used in the same bath with sodium hypochlorite, hydrogen peroxide and reductive bleaching agent and is nonionic. It can be used for whitening polyester, acetic acid, nylon and other fibers. Its light fastness is grade 5 and washing fastness is excellent. In the application of polyester fibers, both dip and pad dyeing can obtain higher whiteness values. It is especially suitable for high temperature and high pressure process.
Usage method (reference amount): ____________
The whitening agent should be dispersed thoroughly in use so that the whitening agent can be uniformly dispersed in the whole polymer and the reaction effect is better.
In actual use, please increase or decrease the dosage according to different whiteness requirements.
Characteristic:
1. It has good thermal stability and high temperature resistance. It does not decompose or sublimate at 300 ~C.
2. Fluorescence intensity, whiteness higher than PF.
3. Natural color and light, strong sun resistance.
