Products Description
Polyurethane cam lock sandwich panels consist of a core made of polyurethane foam, sandwiched between two outer layers, which are typically made from sheet metal such as galvanized steel or aluminum. Panels are available in a variety of thicknesses, typically 100mm to 200mm, depending on specific insulation requirements.

Advanced Coatings
The surface material can be enhanced with various advanced coatings:
- PVDF (Polyvinylidene Fluoride): Exceptional resistance to UV radiation, chemicals, and weathering. Ideal for outdoor architectural projects.
- HDP (High-Durability Polyester): Superior scratch resistance and durability for high-traffic industrial environments.
- EP (Epoxy Polyester): Excellent adhesion and chemical resistance, perfect for indoor applications.
Key Features of PUR/PU Cam Lock Panels
- High Thermal Insulation: Thermal conductivity coefficient (λ) of approximately 0.023-0.025 W/m·K.
- Cam Lock Design: Enables fast, secure connection and ensures a tight seal against air leakage.
- Lightweight: Easy to handle and install, reducing structural load on buildings.
- Moisture-proof: Closed-cell structure prevents moisture absorption and mold growth.
Frequently Asked Questions
Q1: What is the thickness range for these sandwich panels?
A: Our panels are typically available in thicknesses ranging from 100mm to 200mm, depending on your specific insulation and cold storage requirements.
Q2: What is the thermal conductivity of the polyurethane core?
A: The polyurethane foam provides excellent insulation with a thermal conductivity coefficient (λ) of approximately 0.023-0.025 W/m·K.
Q3: How does the cam-lock mechanism benefit the installation?
A: The cam-lock design allows for fast and secure panel connections, ensuring a tight seal that minimizes air leakage and maximizes thermal efficiency.
