Polyfil® HG

Polyfil HG is an very fine, water-washed spray dried kaolin engineered for high-performance rubber and plastic applications. With a neutral pH and extremely low levels of crystalline silica and salts, Polyfil HG provides a unique combination of acid resistance, barrier properties, and reinforcement, making it ideal for use in tires, wire & cable insulation, and demanding industrial formulations.

‍

• Ultra-Fine Particle Size: Supports excellent dispersion and surface smoothness in elastomeric systems
• Acid Resistance: Ideal for applications exposed to harsh environments or corrosive conditions
• Barrier Properties: Enhances moisture and gas impermeability in tire and cable systems
• Reinforcement Capability: Improves tensile strength and durability in rubber compounds
• Low Crystalline Silica & Salt Content: Enhances safety, processing, and long-term material stability
• Neutral pH: Ensures compatibility across a broad range of polymer systems
