Polyfil® DL

Polyfil DL is the industry standard delaminated kaolin for use in tire innerliners. Engineered with large, platy particles, Polyfil DL is designed to significantly reduce gas and vapor permeability, enhancing air retention and extending tire performance.

‍

• Reduced Permeability: Large, platy particles create a tortuous path that effectively slows gas and vapor transmission
• Innerliner Industry Standard: Trusted by leading tire manufacturers for consistent performance in demanding applications
• High Aspect Ratio: Enhances barrier performance while maintaining compound flexibility and processing efficiency
• Delaminated Structure: Improves dispersion and compatibility in elastomeric systems
