Negative Ion Powder

Negative ion powder is a functional mineral powder produced from selected natural mineral materials such as tourmaline-based minerals, ceramic minerals, and other functional inorganic materials through crushing, grinding, purification, classification, and surface treatment if required. It is designed for customers who need a mineral additive that can be incorporated into coatings, plastics, ceramics, textiles, rubber, building materials, water treatment media, and other functional products.

Unlike ordinary mineral fillers, negative ion powder is mainly valued for its functional mineral characteristics. It can be used as a special additive in formulas where customers want to develop products with mineral functionality, far infrared reference performance, negative ion reference performance, improved product image, and differentiated market value. It is often used together with tourmaline powder, far infrared powder, ceramic powder, calcium carbonate, talc powder, mica powder, and other industrial mineral fillers.

WANCHENG MINERAL supplies negative ion powder in different fineness levels, colors, and formulations according to customer applications. Common product forms include fine powder, ultra-fine powder, and customized functional mineral powder blends. The particle size can be adjusted according to different processing systems, such as water-based coatings, solvent-based coatings, plastic masterbatch, ceramic glaze, textile finishing slurry, rubber compounds, and composite materials.

For international buyers, negative ion powder should be selected based on the final product use, required fineness, color requirement, compatibility with the formula, dosage level, dispersion performance, packaging, and testing method. Because different markets have different regulations for functional or wellness-related claims, WANCHENG MINERAL recommends that customers verify performance through their own third-party testing and use compliant marketing language in their local markets.

As a professional mineral supplier, WANCHENG MINERAL focuses on stable raw material selection, controlled grinding, particle size classification, batch inspection, clean packaging, and export supply support. Our goal is to help customers source negative ion powder with consistent quality and practical industrial usability.

    Technical Specifications

    Negative ion powder can be supplied in different grades according to the target application. For coating and textile applications, customers often prefer fine or ultra-fine powder with good dispersion and smooth surface effect. For ceramics, building materials, and functional fillers, customers may choose medium or fine powder according to processing requirements. For plastic and rubber applications, particle size, heat resistance, and compatibility with resin or rubber systems are important.

    The typical product color may be off-white, light gray, gray, black-gray, or customized depending on the mineral formulation. If customers require a light-colored product for coatings or plastics, the raw material and formula should be confirmed before bulk order. For darker functional mineral formulations, the powder may be more suitable for applications where color influence is acceptable or where functional positioning is more important than whiteness.

    The negative ion release value and far infrared reference performance can vary depending on mineral composition, particle size, testing environment, humidity, test method, and dosage. Therefore, these values should be treated as reference data and confirmed through testing according to the customer's final product and market requirements.
