Product Description
High-Density Rock Wool Boards With Stable Performance For Power Plant Pipe Insulation
Rock wool boards are produced using natural minerals like basalt as raw materials. The rocks are melted at high temperatures, then spun into fibers via centrifugal force. The density of rock wool board is the key indicator determining its performance and application.
Key Advantages
High-density construction (120-200 kg/m³) for superior strength and stability
Exceptional fire resistance (2-4 hour rating) and high-temperature stability
Long service life (≥20 years) with minimal maintenance requirements
Superior thermal performance with stable conductivity (0.036-0.042 W/(m*K))
Excellent sound absorption (80-90% of high-frequency noise)
Performance Characteristics
High-density rock wool boards offer precise alignment with the core demands of power plant insulation, outperforming common materials like polyurethane foam, glass wool, and XPS boards in high-temperature, high-safety applications.
Cost Efficiency: Despite 20-30% higher initial cost than glass wool, rock wool proves more economical long-term with 15-20 year lifespan versus 3-5 years for glass wool.
Adaptability: Can be shaped to fit irregular equipment like pipelines and boilers, reducing thermal bridging.
