Overview
Imerys is a world leader in mineral-based specialty solutions, operating across more than 40 countries with over 250 industrial sites. The company transforms minerals into value-added products that serve as essential components in everyday applications. Founded through the merger of English China Clays and Imetal in 1999, Imerys has grown through strategic acquisitions to become a comprehensive mineral solutions provider. Imerys focuses on four main business segments: Performance Minerals, Refractory & Abrasives, Construction Minerals, and Filtration & Additives. Each segment serves distinct industrial markets with tailored mineral formulations. The company invests significantly in R&D to develop innovative mineral applications, holding over 1,000 patents worldwide.
Physical and Chemical Properties
Imerys' mineral products exhibit diverse physical and chemical characteristics depending on their composition and processing. Common minerals include kaolin (hydrated aluminum silicate), calcium carbonate, talc (hydrated magnesium silicate), and perlite (volcanic glass). These typically appear as white or off-white powders with varying particle sizes from submicron to several millimeters. Key chemical properties include pH stability (neutral to alkaline for most products), low solubility in water, and thermal resistance up to 1000°C for refractory-grade materials. Many products demonstrate high brightness (90+ GE for premium kaolins) and controlled rheological behavior. The company offers surface-treated variants for improved compatibility with organic matrices in plastics and paints.
Main Applications
In ceramics, Imerys minerals provide whiteness, plasticity, and thermal stability for sanitaryware, tableware, and technical ceramics. The construction sector utilizes their products as fillers in concrete, asphalt modifiers, and lightweight aggregates. Paper manufacturers rely on Imerys kaolins and calcium carbonates for coating and filling applications to enhance print quality and opacity. The paints and coatings industry benefits from minerals that improve hiding power, weather resistance, and viscosity control. Plastic compounds gain enhanced mechanical properties, dimensional stability, and flame retardancy through mineral incorporation. Specialty applications include filtration aids for beer and wine clarification, cat litter absorbents, and pharmaceutical excipients that meet stringent purity requirements.
Safety and Storage
Most Imerys mineral products are classified as non-hazardous under normal handling conditions, though dust generation requires proper ventilation and personal protective equipment (PPE). Specific safety considerations depend on the mineral type - for example, crystalline silica-containing materials need special dust control measures to prevent respiratory exposure. Storage recommendations typically include keeping products in original packaging or sealed containers in dry conditions (below 80% relative humidity). Temperature-sensitive minerals like some functional fillers require climate-controlled warehousing. Bulk mineral storage should prevent contamination and moisture absorption that could affect product performance. Always consult the Material Safety Data Sheet (MSDS) for product-specific handling guidelines.
B2B Procurement Guide
When sourcing from Imerys, industrial buyers should clearly specify technical requirements including mineral grade, particle size distribution (PSD), chemical composition limits, and functional performance criteria. The company offers technical support to help select the optimal mineral solution for specific applications, often providing sample testing. Procurement volumes significantly affect pricing - full truckload (FTL) shipments generally offer better rates than less-than-truckload (LTL) quantities. For international buyers, Incoterms should be negotiated considering mineral shipping characteristics (some products may require moisture-proof containers). Long-term supply agreements often include price adjustment mechanisms tied to energy and transportation cost fluctuations.
