Ultramarine blue pigment is widely used in natural and synthetic rubber compounding to impart blue coloration. Its excellent heat resistance, which allows processing at rubber vulcanization temperatures, makes it a preferred choice.
In rubber applications, the pigment must disperse uniformly in the compound to avoid streaking or color variation in the final product. Ultramarine blue, with its well-controlled particle size, disperses well in rubber matrices using standard mixing equipment.
Shree Krishna Ultramarine Pigments (P) Limited supplies rubber-grade ultramarine blue that is compatible with both natural rubber and synthetic rubber compounds including SBR, NBR, and EPDM. Our pigment is tested for dispersion quality and heat stability.
The pigment’s non-toxic profile is particularly important in rubber goods used in food contact or medical applications. Ultramarine blue meets global safety standards, making it compliant for these sensitive end uses.
Manufacturers of rubber gloves, profiles, hoses, and molded goods benefit from ultramarine blue’s consistent quality, which reduces batch-to-batch variation and contributes to a more predictable production process.
