Nucap® 290W

Nucap 290W is a high-brightness, silane-treated hydrous kaolin engineered for use in elastomeric systems. Featuring the highest level of surface treatment in the Nucap product line, Nucap 290W delivers superior mechanical properties and water resistance. Nucap 290W is especially effective in soft, low-shear compounds, offering excellent dispersion, faster mixing, and potential reduction in added silane.

‍

• Maximum Surface Treatment: Provides the best balance of reinforcement, water resistance, and durability
• Reduced Silane Requirement: High treatment efficiency allows formulators to use less added silane without sacrificing performance
• Superior Dispersion: Aids rapid, uniform mixing in soft and low-shear applications like tubing, stoppers, and printing blankets
• Enhanced Mechanical Properties: Improves strength, flexibility, and resistance in rubber compounds
• High Brightness: Ideal for light-colored and non-black rubber formulations
