Optical Brightener
Introduction: Optical brightener is not the more added amount, the better the whitening effect, it belongs to a kind of fine chemical industry. Fluorescent whitening agent is used to emit blue or blue-violet fluorescence and yellow light in recycled plastic particles. Complementary, emitting white light, this is an optical brightening method, allowing people to visually see that the white plastic particles are more white and brighter, and the colors are more vivid and eye-catching.
Performance Features: 1. Appearance: light yellow powder, tasteless2, good light transmittance, suitable for transparent plastic products, paint ink industry3. Small toxicity, suitable for environmental protection requirements, shallow color, pure color, moderate price.4. Solubility: insoluble in water, soluble in alkanes, mineral oils and common organic solvents.5. Maximum absorption wavelength of light: 357nm (ethanol)6. The maximum fluorescence emission wavelength is 435nm.
Applicable Scope: 1. Injection molding, blowing film, color masterbatch, PVC building materials2. PE, PP, PS, ABS3, transparent plastic products, hot melt plastic4.
