Barium Sulfate Filler 98% | Drilling Mud Weighting Agent & Plastic Additive

Multifunctional Barium Sulfate for Energy and Manufacturing Industries

Our Barium Sulfate Filler with a guaranteed minimum purity of 98% serves as a critical performance material in two major industrial domains: petroleum exploration and polymer manufacturing. This versatile product, also known as barite when referring to its natural mineral form, undergoes careful processing and quality control to ensure it meets the demanding specifications of both applications. As a Drilling Mud Weighting Agent, it plays an essential role in maintaining well control and operational safety in oil and gas drilling operations. Simultaneously, as a Plastic Additive, it enhances the performance characteristics of polymer composites across multiple sectors. This dual functionality demonstrates the material's unique combination of high density, chemical inertness, and favorable economics that make it irreplaceable in these applications.

Drilling Mud Weighting Agent: Critical Functions in Petroleum Operations

In the petroleum industry, our 98% pure barium sulfate serves as the primary Drilling Mud Weighting Agent in water-based, oil-based, and synthetic-based drilling fluids. Its exceptionally high specific gravity (approximately 4.2-4.5 g/cm³) makes it ideal for increasing mud density to control formation pressures and prevent blowouts. When added to drilling fluids, it creates hydrostatic pressure that counters the pressure of oil, gas, or water formations encountered during drilling. Our product meets or exceeds API (American Petroleum Institute) Specification 13A for drilling-grade barite, with particular attention to particle size distribution (minimum 97% passing through 200 mesh/74 microns), specific gravity requirements, and soluble alkaline earth metal content. The material's chemical inertness ensures compatibility with various drilling fluid additives and minimizes undesirable reactions with formation components. Additionally, its relatively soft nature (3-3.5 on the Mohs hardness scale) reduces abrasion on drilling equipment compared to alternative weighting materials.

Plastic Additive: Enhancing Polymer Performance Across Industries

As a Plastic Additive, our barium sulfate filler offers numerous advantages that improve both the processing characteristics and final properties of polymer compounds. Its high density contributes to sound damping properties in automotive applications, weight management in consumer products, and radiation shielding in specialized applications. Unlike many mineral fillers, barium sulfate exhibits excellent chemical resistance and thermal stability, making it suitable for use with engineering plastics that undergo high-temperature processing or encounter aggressive chemical environments. In PVC compounds, it improves dimensional stability, surface hardness, and weathering resistance while functioning as an effective acid scavenger. For polyolefins, it enhances stiffness and heat deflection temperature without significantly impacting impact strength when properly compounded. The material's white color and low oil absorption make it particularly valuable in applications requiring color consistency and minimal effects on melt flow characteristics.

Processing and Quality Considerations for Dual Applications

The production of our 98% barium sulfate filler involves careful beneficiation of natural barite ore followed by processing to achieve the required purity and particle size characteristics. For drilling applications, the material is typically ground to meet API specifications while maintaining optimal rheological properties in drilling fluids. For plastic applications, additional processing may include surface treatment with coupling agents to improve polymer-filler adhesion and dispersion characteristics. Quality control measures for both applications include regular testing for specific gravity, particle size distribution, chemical composition, and moisture content. We maintain separate quality protocols for drilling-grade and plastic-grade materials to ensure each meets the specific performance requirements of its intended application. This specialized approach allows customers to select the optimal grade for their needs without compromising performance or economics.
