Polyfil® 90

Polyfil 90 is a high-brightness, fine particle size calcined kaolin designed for a wide range of industrial plastic and rubber applications. Its engineered structure offers enhanced opacity, whiteness, and reinforcement.

‍

• Brightness / Whiteness: Ideal for white and light-colored compoundsReinforcement: Moderate reinforcement in rubber due to fine particle size
• Dimensional Stability: Reduces shrinkage and improves dimensional control
• Barrier Properties: Improves gas and moisture resistance in films and packaging
• Thermal Stability: Excellent high-temperature resistance (non-melting, non-softening filler)
• Electrical Insulation: Maintains dielectric strength in wire & cable compounds
• Processability: Good dispersion in most thermoplastics and elastomers
• Cost Reduction: Replaces more expensive resins or reinforcing agents
