Threetex Optical Brightener

browse around this site JMB is pleased to offer Threetex optical brightener (CI Optical Brightener 184) to the UK plastics industry for use in a wide variety of materials including polyolefins, polystyrenes and PVC. These plastics can often appear pale orange-yellow in sunlight because of absorption of the blue-violet wavelength radiation by impurities and relatively strong reflection of the orange-yellow range. When a small amount of optical brightener is used, the incident UV radiation is absorbed and re-emitted in the visible blue-violet range, counteracting the yellowish tinge.
