Nucap® 190W

Nucap 190W is a high-brightness, silane-treated hydrous kaolin engineered as a reinforcing extender in elastomeric systems. Optimized for fast mixing and improved dispersion, Nucap 190W enhances performance in soft, low-shear rubber compound, making it ideal for applications such as stoppers, tubing, printing blankets, and tire formulations. In addition to offering enhanced dispersibility, the high brightness promotes use in non-black rubber formulations such as white roofing membranes and white tire sidewalls. 

‍

• Reinforcing Extender: Provides mechanical reinforcement and filler functionality for elastomers
• Silane Efficiency: Reduces the need for additional silane while improving filler-polymer interaction
• Enhanced Dispersion: Mixes easily in soft compounds and low-shear processes, improving consistency and compound quality
• High Brightness: Offers a clean appearance suitable for light-colored rubber and non-black compounds
