Description

Polyisocyanurate is a high-performance thermoset polymer belonging to the polyurethane family, renowned for its exceptional thermal stability and flame resistance. This material is critical for applications demanding superior insulation properties and structural integrity under high temperatures. It is extensively utilized in the construction, appliance, and industrial insulation sectors where energy efficiency and fire safety are paramount.

Application

• Rigid Foam Insulation Panels: Primary component in PIR (Polyisocyanurate) foam boards for wall, roof, and cavity wall insulation in commercial and residential construction.
• Industrial Pipe and Equipment Insulation: Used for insulating pipes, tanks, and industrial equipment requiring high-temperature stability and low thermal conductivity.
• Appliance Insulation: Core material in refrigerators, freezers, and water heaters for effective thermal management.
• Metal Composite Panels (MCP): Serves as the insulating core in architectural cladding and facade systems.
• Cold Storage and Refrigerated Transport: Essential for constructing energy-efficient cold rooms and insulated truck bodies.
• Aerospace and Marine Applications: Used in lightweight, fire-resistant insulation for aircraft and ships.

Quality Control

Our Polyisocyanurate is manufactured under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified against key parameters including isocyanurate content, viscosity, and reactivity. We adhere to relevant industry standards and a Certificate of Analysis (COA) detailing specific lot characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and moisture. Recommended storage temperature is between 15°C and 25°C. Keep container sealed when not in use to prevent moisture absorption and premature reaction.
