Product Introduction:
High whiteness calcium hydroxide (commonly known as high white slaked lime, chemical formula Ca(OH)₂) is a high-purity, environmentally friendly inorganic powder material. Made from high-quality limestone through calcination, hydration, purification and ultra-fine grinding, it has a whiteness of more than 90%, even up to over 92% for high-quality products, with high purity, low impurities, adjustable particle size according to needs, good dispersibility, non-toxicity and environmental friendliness.
This material is in the form of white powder, slightly soluble in water, with strong alkalinity and excellent chemical stability. It can be uniformly mixed with various substrates and has good compatibility. In addition to being used as a functional filler in plastic and rubber production, it is also widely applied in many fields such as environmental protection, food, agriculture and construction.

The applications of Calcium Hydroxide :
In the production system of the plastic and rubber industry, fillers are indispensable core auxiliary raw materials. They not only reduce production costs, but also optimize the physical properties and processing performance of products, and even endow products with special functions. As a new type of environmentally friendly functional filler, high whiteness calcium hydroxide (commonly known as high white slaked lime), with its excellent physical and chemical properties, cost advantages and environmental compatibility, has broken the application limitations of traditional fillers, realized large-scale application in plastic and rubber production, and become an important support for promoting the green upgrading of the industry and improving product quality and efficiency.
The reason why high whiteness calcium hydroxide stands out in plastic and rubber production lies in its unique advantages different from ordinary calcium hydroxide. Compared with traditional fillers, the whiteness of high whiteness calcium hydroxide can reach more than 90%, and some high-quality products can even reach more than 92%. It has a pure and uniform color without obvious impurity black spots. It can improve the whiteness and gloss of products without adding additional white pigments, which greatly reduces the usage of high-priced pigments such as titanium dioxide, saves production costs for enterprises, and avoids performance fluctuations caused by pigment addition . In addition, high whiteness calcium hydroxide has high purity (calcium hydroxide content ≥ 95%), and the content of impurities such as silicon dioxide and magnesium oxide is less than 1%. The particle size can be flexibly adjusted between 800 mesh and 2000 mesh according to requirements. The ultra-fine powder has excellent dispersibility, which can be uniformly mixed with plastic and rubber substrates without agglomeration, ensuring the stability of product performance . At the same time, it has good chemical stability and environmental friendliness, non-toxicity and no peculiar smell, which meets the core requirements of modern industry for environmentally friendly materials and is suitable for the production of various high-end and environmentally friendly products.
