for strong, colorful rubbers and plastics
Advances in polymer chemistry have spurred a revolution in rubber and plastic production that has left its mark in every field of industry, as well as in our daily lives.
A few of the results are higher-performance tires and parts for trucks, improved bicycle tires and jogging shoes, longer-lasting drainpipes and garden hoses, and lighter, more attractive audio and video equipment.
Drawing on a wealth of experience, Shiraishi has perfected Hakuenka CC, Hakuenka CCR, Vigot-10 and many other products with the special properties required for stronger and more attractive rubber and plastic.
Our originally developed calcium carbonates add strength, durability and rigidity to tires and conveyor belts; increase the heat and weather resistance of electric cables, pipes, films and home appliances; and stimulate product diversification with their simpler processing and forming.
Low-cost, readily available Shiraishi calcium carbonates are the key to product improvements as well as operating economies.
More than just a manufacturer, Shiraishi is a technological development organization that responds to diverse needs and opportunities with carefully prepared new products.
Our research begins with hypothetical or actual end users, and proceeds through painstaking material tests.
The development process is complete when the precise properties for a specific need have been determined and satisfied with the perfect product.

Poisonous fumes from fires and smokestacks, incinerator breakdowns due to excessive heat, waste disposal dilemmas - all of these are serious social problems, and each can be at least partially solved by adding calcium carbonate to rubber and plastic.
During incineration, calcium carbonates absorb poisonous gases and decrease combustion, providing added margins of both purity and safety.
For example, calcium carbonate having fine particles is formulated in plastic bag for waste which many local governments like Tokyo promotes to use. This means calcium carbonates play a role to protect environment and to keep safe human life.
