KaiYuan Mat
Shared Strengths:
Minimal high-temperature holding force decay; supports large-gap designs with reduced canning precision requirements;
Unrestricted global market access; exempt from REACH regulations;
Shared Limitations:
Highest raw material and manufacturing cost across all fiber systems
PCW mats utilize polycrystalline alumina or mullite fibers as the base matrix, representing the highest temperature-rated commercial mat category. Continuous operating temperatures reach 1000°C–1200°C, with higher short-term tolerance. Stable crystalline structure and low creep rate fundamentally resolve holding force decay from amorphous fiber shrinkage—making this the premier choice for heavy-duty commercial vehicles, large-displacement engines, and extreme-duty canning applications.
Composition & Function
Strengths & Limitations
Employs nonwoven needling technology to interlock fiber bundles into 3D structures with minimal organic binder requirements. Delivers exceptional thermal shock resistance and erosion resistance against pulsating exhaust flow.
Optimal for: Close-coupled mounting, severe vibration, and pulsating exhaust environments.
Limitations: High capital investment, lower productivity, and 20–30% higher unit cost versus wet-laid. Thickness range constrained by process—ultra-thin and ultra-thick gauges unavailable.
Utilizes conventional paper-making technology: fiber dispersion, dewatering, and drying. Delivers uniform thickness and smooth surfaces with mature process control.
Optimal for: Standardized mass production and applications requiring ultra-thin or ultra-thick gauges. The cost-performance choice for moderate-to-high temperature duty cycles.
Limitations: Organic content comparable to ceramic fiber non-intumescent mats—significantly higher than needled variants.

Wet-laid Mat
Polycrystalline Wool (PCW) Mat
The ultimate solution for performance-driven projects—wet-laid for economy and consistency, needled for extreme-duty reliability.
