Non-Asbestos Compressed Fibre

Compressed Non-Asbestos Fibre (CNAF) jointing represents the modern, safe standard for general-purpose soft gaskets. Formulated with high-strength synthetic fibers bound in premium elastomers, these gaskets deliver exceptional performance across a broad spectrum of industrial media.

Key Materials

  • Aramid Fibers
  • Synthetic Fibers
  • NBR Binder

Primary Industries

  • Chemical
  • Water Treatment
  • Food & Beverage

Compressed Non-Asbestos Fibre (CNAF) jointing is the industry’s answer to the phasing out of asbestos-based materials. By combining high-tensile aramid and synthetic fibers with specialized elastomer binders, we produce a sealing material that excels in general-purpose utility piping and mid-range chemical processing.

Manufacturing and Processing

Our CNAF materials are calendered under intense pressure, resulting in a dense, uniform sheet with excellent impermeability. We utilize advanced CNC oscillating knife cutters to convert these sheets into precision gaskets of any shape or size, eliminating tooling costs and enabling rapid prototyping.

Material Selection

The choice of binder (NBR, SBR, or EPDM) determines the gasket’s final chemical compatibility. Our engineering team can recommend the exact CNAF grade required whether you are sealing oils, fuels, water, steam, or mild chemical media.
