Specification

PU Sealing Rock Wool Sandwich Panel

PU Sealing Rockwool Sandwich Panel is a high-performance composite panel with core advantages of thermal insulation, fire resistance, and airtightness.
Key Features
Superior Insulation: The PU (Polyurethane) layer offers low thermal conductivity, while rockwool enhances fire resistance (reaching A1 class, non-combustible).
Strong Sealing: PU's dense structure and seamless bonding eliminate air leakage, boosting energy efficiency.
Durability: Resists moisture, corrosion, and deformation, suitable for long-term outdoor use.
Formation Process
Core Material Preparation: Rockwool is processed into slabs; liquid PU is foamed and cured.
Lamination: PU is bonded between rockwool core and surface layers (e.g., steel sheets) via high-pressure pressing.
Sealing Treatment: Edges are sealed with PU adhesives to ensure airtightness and structural integrity.
Applications
Widely used in industrial workshops, cold storage facilities, clean rooms, and exterior walls of high-rise buildings. It meets strict requirements for fire safety, energy saving, and environmental protection in construction and refrigeration sectors.
