Optical Brightening Agent For Plastics

Approx. Rs 1,000 / KgGet Latest Price

Plastic brighteners, or optical brightening agents (OBAs/FWAs), are chemical additives used in manufacturing to enhance the whiteness and brilliance of plastic products. They function by absorbing ultraviolet (UV) light and emitting it as blue light, effectively masking yellowing and enhancing aesthetic appeal. These agents are ideal for plastics like PVC, PET, PS, ABS, and PE.
