HIFILL® N 300

HIFILL® N 300 by Covia is a nepheline syenite-based functional filler, pigment dispersant and extender for plastic and rubber applications. It is an all-natural sodium-potassium alumino silicate mineral. It exhibits excellent color stability as well as chemical-, scratch- and mar resistance. It provides an optimal balance of physical, optical and mechanical properties, enhancing the durability of the final product. It is a crystalline silica-free alternative to ground or microcrystalline silica mineral fillers.

• It offers reduced formulation cost, superior weatherability, low oil absorption and color extension in pigment dispersions.
• It provides high dielectric resistance, thermal conductivity, compressive strength and easy masterbatch processing with higher loadings.
• It exhibits brighter and less yellowness overtones in pigmented silicone elastomer applications.
• It shows superior UV resistance with photochemical and abrasion advantages, as compared with calcium carbonate.
• The recommended dosage level is up to 50% by weight of the polymer.
• It is listed 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.
• HIFILL® N 300 is NHC (China) and FDA approved for indirect food-contact applications.
