KaiYuan Mat
Strengths: Mature, stable RCF supply chain; outstanding cost-performance ratio; Vermiculite expansion broadens effective holding force temperature window; Strong process adaptability; suitable for standardized mass production.
Limitations: EU REACH restricted substance; registration required for EU export; Inferior long-term temperature resistance and thermal aging vs. PCW mats.
Conclusion: Optimal for cost-sensitive applications with moderate operating temperatures and no special environmental compliance requirements.
Ceramic fiber intumescent mats are engineered fiber-based sealing and retention materials comprising RCF (refractory ceramic fiber), vermiculite, and organic binders. These components function synergistically:
RCF: Forms the high-temperature-resistant skeleton, providing structural integrity and thermal insulation
Vermiculite: Key functional filler that expands upon heating, generating supplemental compression force to compensate for fiber shrinkage-induced holding force decay at elevated temperatures
Organic binder: Imparts flexibility and formability during manufacturing and installation; burns off during initial high-temperature operation without affecting long-term performance
Composition & Function
Strengths & Limitations
Suitable for continuous operating temperatures ≤850°C. Widely deployed in road vehicles (gasoline/diesel engines), non-road mobile machinery, and marine engine DOC, SCR, and DPF systems. Particularly cost-effective for underfloor catalyst mounting positions where exhaust temperatures are moderate and thermal shock is minimal. Not recommended for close-coupled turbocharger outlet applications or environments with extreme thermal shock.
Applications
RCF Intumescent Mat
For cost-sensitive applications with moderate temperature requirements and no mandatory environmental compliance constraints.
