Application：
UV 390B is an ultraviolet absorber, specially designed to protect PET (polyethylene terephthalate) bottles and their contents from ultraviolet (UV) damage.
UV 390B can be directly integrated into PET. Tests show that it will not migrate out of the plastic and contaminate the product, while maintaining the crystal clarity of PET.
Adding UV 390B to PET packaging can reduce wastewater pollution caused by some chemicals traditionally used in other UV stabilizers.
