Product Description

Product Introduction

Barium sulfate, a white, odorless powder, excels as a filler/extender. In paints/inks, it boosts hiding power and surface smoothness. For plastics, it enhances hardness, stiffness, and wear - resistance. In ceramics/glass, it refines melting properties and stability. In electronics, it serves in packaging for insulation.In cosmetics, high - purity barium sulfate (fine - sized) ensures smooth skin texture. Medically, it's a key X - ray contrast agent for GI tract imaging. In food, used sparingly as an additive (e.g., anti - caking), strictly regulated.

Product Application

In Paint, Ink, Coating, Plastic, Ceramic, Glass, and Electronics

• Paint and Ink: In paint formulations, barium sulfate can be used in both water - based and solvent - based paints. It reduces the cost of the paint by replacing some of the more expensive pigments while maintaining or even improving the paint's performance. In inks, it helps to improve the ink's drying properties, color fastness, and printability.
• Plastic: It is added to plastics such as polypropylene, polyethylene, and PVC. It can enhance the dimensional stability of plastics, reduce shrinkage during the molding process, and improve the heat resistance of the final products.
• Ceramic and Glass: In ceramics, it is used in glazes to improve the glaze's appearance and durability. In glass manufacturing, it can act as a clarifying agent, removing bubbles and improving the transparency of the glass.
• Electronics: In electronic packaging materials, barium sulfate can improve the mechanical strength and electrical insulation properties of the materials, protecting the electronic components inside.

In Cosmetics, Medicine, and Food

• Cosmetics: It is used in face powders, blushes, and other powder - based cosmetics. It helps to absorb excess oil on the skin, gives a matte finish, and can also improve the adhesion of other cosmetic ingredients to the skin.
• Medicine: As mentioned, the main application is in X - ray imaging of the gastrointestinal tract. It provides a clear contrast on X - ray images, allowing for accurate diagnosis of digestive system diseases.
• Food: Although used in a very limited way, it may be used as a processing aid or a functional additive in some food products under strict regulatory control to meet specific technical requirements.
