Paper Grade materials are specialized chemicals and additives used in the manufacturing and treatment of paper and paper-based products. These materials are formulated to enhance properties such as strength, brightness, printability, smoothness, and water resistance, making them essential throughout the papermaking process—from pulp preparation to finishing.

Applications include:

Pulp processing – aiding in fiber separation, bleaching, and purification

Wet-end additives – improving paper formation, drainage, and retention of fine particles

Sizing and coating – enhancing print quality, surface strength, and resistance to ink penetration or moisture

Dry strength and wet strength enhancement – improving durability during use and handling

Defoaming and cleaning – ensuring smooth operation and reducing production downtime

Calcium carbonate (Coated)

Original price was: $3,500.00.Current price is: $3,300.00.
Calcium Carbonate (coated) refers to a form of calcium carbonate in which the individual particles of the mineral are coated or encapsulated with a layer of a different material. This layer can be composed of various substances, such as stearic acid, fatty acids, or other polymers. The purpose of the coating is to modify the surface properties of the calcium carbonate particles, such as their hydrophobicity or compatibility with other materials, making them more suitable for specific applications. Coated calcium carbonate is widely used in industries such as plastics, paper, paints, and coatings, where it can improve the properties of the final product, such as brightness, whiteness, and durability.
