Shiraishi Kogyo Kaisha Hakuenka CC is our original Ultra-fine precipitated calcium carbonate coated with organic compounds. It was originally developed for reinforcing rubber materials in the early 20th century. Hakuenka CC has 50 nm uniformed ultra-fine particles as primary particle. These particles are surface treated with fatty acid in order to improve dispersion property at mixing stage with organic materials. Hakuenka CC is specially applied for construction application where Silicone & Polysulfide sealants are used. Hakuenka CC is commonly used as other application such as rubber, plastics and so forth.

Shiraishi Kogyo Kaisha White IGV-IV is a ultra-fine calcium carbonate which has 80 nm of primary particle size.These particles are surface coated with rosin acid to improve dispersion property at the mixing. White IGV-is developed and designed for gravure ink as extender pigments.White IGV-is easy to disperse and provides both high gloss and transparency to those ink products.White IGV-also provides adequate low viscosity which is required for gravure ink.

Shiraishi Kogyo Kaisha Hakuenka DD is our original Ultra-fine precipitated calcium carbonate coated with organic compounds. It was originally developed for reinforcing rubber materials in the early 20th century. Hakuenka DD has 50 nm uniformed ultra-fine particles as primary particle. These particles are surface treated with rosin acid in order to provide compatible surface modification when it is mixed with organic materials or with vehicle or diluents. Hakuenka DD is specially applied for off-set ink, natural and synthetic rubber application. Hakuenka DD is also used as other application such as printing ink, rubber and so forth.
