Description

Saponite is a naturally occurring trioctahedral smectite clay mineral, valued for its high cation exchange capacity, swelling properties, and excellent rheological characteristics. This versatile material is crucial for applications requiring superior thickening, gelling, and suspension stabilization. Key industries that rely on Saponite CAS NO 66732-77-2 include drilling fluids, paints & coatings, ceramics, and advanced material synthesis.

Application

• Drilling Fluids: Acts as a high-performance viscosifier and fluid loss control agent in water-based muds for oil and gas exploration.
• Paints & Coatings: Functions as a rheology modifier and thickener, providing anti-sag properties and improved suspension of pigments.
• Ceramics & Refractories: Used as a plasticizer and binder to improve the workability and green strength of clay bodies.
• Catalyst & Catalyst Support: Serves as a catalyst or porous support material in petrochemical and organic synthesis due to its acidic sites and layered structure.
• Adsorbents: Employed for the removal of heavy metals, organic contaminants, and dyes from industrial wastewater.
• Nanocomposites: A key precursor for polymer-clay nanocomposites, enhancing mechanical, thermal, and barrier properties.
• Personal Care & Cosmetics: Utilized as a natural thickener, suspending agent, and opacifier in formulations like creams and lotions.
• Agriculture: Used as a soil conditioner to improve water retention and nutrient delivery in sandy soils.

Quality Control

Our Saponite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency. Quality parameters such as mineral purity, cation exchange capacity (CEC), viscosity, particle size distribution, and moisture content are rigorously tested. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect its performance.
