HIFILL® N 200

HIFILL® N 200 by Covia is an all-natural, nepheline syenite-based functional filler, pigment dispersant and extender for plastic and rubber applications. It provides reduced formulation cost, superior weatherability, low oil absorption and color extension in pigment dispersions. It exhibits excellent color stability as well as chemical-, scratch- and mar resistance. 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, enhancing the durability of the final product.
• It offers high dielectric resistance, thermal conductivity, compressive strength and easy masterbatch processing with higher loadings.
• It provides brighter and less yellowness overtones in pigmented silicone elastomer applications.
• As compared with calcium carbonate, it shows superior UV resistance with photochemical and abrasion advantages.
• HIFILL® N 200 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.
