Sepiolite fiber is a natural mineral fiber, a fibrous variant of sepiolite mineral, called alpha-sepiolite.

Sepiolite fiber is used as an adsorbent, purifier, deodorant, reinforcing agent, suspending agent, thixotropic agent, filler, etc. in water treatment, catalysis, rubber, paint, fertilizer, feed and other industrial aspects. In addition, the good salt resistance and high temperature resistance of sepiolite make it as a high-quality drilling mud material for petroleum drilling and geothermal drilling.
Sepiolite has extremely strong adsorption, decolorization, and dispersion properties, as well as extremely high thermal stability, high temperature resistance up to 1500 ~ 1700 ℃, and excellent moldability, insulation, and salt resistance.
