Product Description

SDB2232 Rigid Polyurethane (PU) Foam for Discontinuous Sandwich Panels

Manufacturer: Yantai Shunda Polyurethane Co., Ltd.

Product Overview
SDB2232 is a high-performance blend polyol designed for manufacturing discontinuous sandwich panels used in cold storage, industrial insulation, and construction applications. This rigid PU foam system utilizes HCFC-141b blowing agent to create panels with exceptional thermal efficiency, structural strength, and durability. The foam bonds seamlessly with various facing materials, including color steel, aluminum, galvanized steel, and stainless steel, making it versatile for diverse insulation needs.

Key Features & Benefits

1. Superior Thermal Insulation Performance

• Ultra-Low Thermal Conductivity (0.021 W/m·K) - Minimizes heat transfer, ensuring energy efficiency in cold storage facilities.

• 94% Closed-Cell Content - Reduces moisture absorption and enhances long-term insulation stability.

2. High Structural Strength & Durability

• Compressive Strength (200 kPa) - Withstands heavy loads, making it ideal for industrial and commercial applications.

• Core Density (40 kg/m³) - Balances weight and strength for easy handling without compromising performance.

3. Excellent Adhesion to Panel Facings

• Bonds strongly with metal surfaces (steel, aluminum, etc.), preventing delamination.

• Suitable for reusable cold storage panels, reducing long-term costs.

4. Easy Installation & Cost-Effective Production

• Simple manufacturing process - Requires minimal equipment investment.

• Lightweight yet rigid - Simplifies construction and reduces labor costs.
