Nano Grade 3000 Mesh High Purity Calcite Powder for Paint Coating and Plastic Masterbatch Filler

Features

The core component of the company's calcium carbonate powder is CaCO₃, with a stable content of over 95%-99%. The content of harmful impurities such as iron and manganese is extremely low, the whiteness can reach 85-98 degrees, the oil absorption value is low, the dispersibility is good, and it has excellent compatibility with various polymer materials and solvent systems. Heavy calcium carbonate powder is made by physical grinding, retaining natural mineral properties, with moderate hardness and high cost performance. 

The conventional specifications cover 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, 2000 mesh, 3000 mesh, etc. Light calcium carbonate powder is prepared by chemical synthesis, with finer particles and controllable crystal form, and has better reinforcing and toughening effects, suitable for high-end fine chemical fields. The entire series of products can be provided with surface modification treatments (such as stearic acid and coupling agent modification) to further improve the product's dispersibility and hydrophobicity, meeting the personalized production needs of different industries.

Application

Chuangwei Minerals' calcium carbonate powder has become the preferred functional filler in various industries due to its core advantages of high whiteness, high purity, uniform particle size, and stable performance. 

In the coating industry, it can improve the hiding power, wear resistance, and scrub resistance of the coating film, and reduce raw material costs. In the plastic and rubber industries, it can enhance the rigidity, hardness, and dimensional stability of products, and improve processing fluidity. In the papermaking industry, it can improve the whiteness, smoothness, and opacity of paper. In the fields of building materials and daily chemicals, it can play the role of filling, whitening, and shaping, optimizing the comprehensive performance of finished products.
