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.
