Plastic & Rubber Grade Barite Powder

Commercial plastic and rubber grade barite is available in several grades and varieties, including Standard Polymer Grade Barite, High-Whiteness Barite, Low-Oil-Absorption Barite, and Micronized Barite, classified according to purity, brightness, and particle size distribution. These grades are designed to meet the specific requirements of different polymer systems. This grade of barite powder is widely used in PVC compounds, masterbatches, rubber sheets, hoses, cables, footwear, automotive parts, sealing materials, and molded plastic products. It increases product density, improves dimensional stability, enhances surface finish, and reduces formulation costs without compromising mechanical or chemical resistance.

Key properties include high specific gravity, excellent chemical resistance, low moisture absorption, good thermal stability, and compatibility with most resins and elastomers. Commercial particle sizes are commonly supplied as 200 mesh and 325 mesh, as well as micronized grades from 2 to 10 µm for high-performance plastic and rubber applications. Plastic & rubber grade barite powder is packaged in 25 kg and 50 kg bags, 1-ton jumbo bags, or bulk supply, providing manufacturers with a reliable, economical, and versatile mineral filler solution for polymer and rubber production.
