Sepiolite Fiber Powder is a natural fibrous magnesium silicate mineral processed through purification, fine milling, fiber classification and silane coupling‑agent surface modification. The inherent micro‑fibrous crystal structure brings reinforcing effects, while its porous inner channel structure endows the material with physical adsorption capacity for volatile odor‑forming substances. After silane surface treatment, the fiber surface becomes organophilic, which improves interfacial bonding w

Product Detail

Product DetailsThis silane‑modified sepiolite fiber powder is produced from selected natural sepiolite ore. Raw mineral material undergoes ore purification, controlled fine grinding and fiber classification to preserve micro‑fibrous morphology and remove rock impurities. Afterwards, dry silane modification treatment is carried out on the surface of mineral fibers.

Untreated sepiolite features strong hydrophilicity. When directly incorporated into rubber or plastic systems, poor compatibility with organic polymer resins easily results in fiber agglomeration, poor dispersion, increased melt viscosity and surface defects of molded articles. Silane surface modification optimizes the surface property of sepiolite micro‑fibers, enhances wettability with molten polymer during compounding, and strengthens interfacial adhesion between mineral fiber and polymer molecular chains.

The unique fibrous structure forms a staggered micro‑fiber network inside rubber‑plastic matrix. It effectively improves tensile strength, flexural modulus and dimensional stability of finished products, reduces thermal shrinkage during molding. The abundant internal microporous channels of sepiolite provide physical adsorption sites for low‑molecular‑weight volatile substances generated from resin decomposition or additive migration. It suppresses unpleasant volatile odors released from rubber and plastic components. It helps lower the total volatile emission of finished polymer parts.

Compared with short glass fiber, sepiolite mineral fiber causes relatively mild abrasion to extrusion screws and injection molds. The product has stable particle‑fiber distribution, low heavy‑metal impurities and consistent adsorption performance.

Typical application fields include modified PP, PE, PA thermoplastic parts, EPDM, NBR, SBR rubber goods, automotive interior polymer components, household plastic parts requiring low‑odor performance, rubber sealing elements and functional plastic masterbatches.

Packaging is 25 kg moisture‑proof woven bags with inner polyethylene liner. Keep packages tightly sealed during transportation and warehouse storage. Store in cool, dry indoor warehouse, prevent moisture absorption which would impair fiber dispersion and adsorption capacity. Avoid excessive stacking height on pallets to prevent bag rupture. Wear dust‑proof masks and protective gloves during powder‑handling operations.
