Sepiolite fiber for friction material ‌thermal insulation coating mortar additive rubber products ‌

Sepiolite fiber, a hydrated magnesium silicate clay mineral, is characterized by its unique needle like structure and remarkable properties. Its fibrous morphology and porous framework endow it with an extensive surface area, high cation exchange capacity, and excellent adsorption capabilities. Major global deposits are located in Spain, Turkey, the United States, and China, formed through complex geological processes involving sedimentation and metamorphism.

 

The production of sepiolite fiber begins with mining raw ore, followed by crushing, grinding, and purification. Advanced treatment methods, such as acid activation and thermal modification, enhance its reactivity and porosity, tailoring it for specific applications. These processes allow manufacturers to control the fiber’s particle size, surface chemistry, and mechanical strength.

 

In environmental applications, sepiolite fiber excels as an adsorbent for heavy metals, organic pollutants, and oil spills. For example, it can effectively remove lead and mercury from industrial wastewater, providing a cost effective and eco - friendly solution. In the chemical industry, it serves as a carrier for catalysts, improving reaction efficiency in petrochemical processes. In agriculture, sepiolite - based soil amendments enhance water retention, nutrient availability, and microbial activity, promoting healthier crop growth. Additionally, in the manufacturing of plastics and rubber, it acts as a reinforcing filler, enhancing mechanical properties. With its versatile uses and sustainable nature, sepiolite fiber continues to play an increasingly important role across multiple sectors.
