HIFILL® N 800

HIFILL® N 800 by Covia is an all-natural, nepheline syenite-based functional filler, pigment dispersant and extender. It is recommended for plastic and rubber applications. It offers excellent color stability, chemical-, scratch- and mar resistance. It provides brighter and less yellowness overtones in pigmented silicone elastomer applications. It is a crystalline silica-free alternative to ground or microcrystalline silica mineral fillers.

• It imparts an optimal balance of physical, optical and mechanical properties, and enhances the durability of the final product.
• It offers high dielectric resistance, thermal conductivity, compressive strength and easy masterbatch processing with higher loadings.
• It provides reduced formulation cost, superior weatherability, low oil absorption and color extension in pigment dispersions.
• As compared with calcium carbonate, it exhibits superior UV resistance with photochemical and abrasion advantages.
• HIFILL® N 800 is included on Japan's Positive List and complies with EU Plastic Regulation No. 10/2011, RoHS, Kosher, CONEG and OSHA’s respiratory crystalline silica (RCS) regulations.
• It is NHC (China) and FDA approved for indirect food-contact applications.
• The recommended dosage level is up to 50% by weight of the polymer.
