SDF2702 is a high-density rigid polyurethane (PU) foam specially formulated for imitation wood applications, including decorative blocks, architectural moldings, and furniture components. When combined with PM200 isocyanate, it creates a lightweight yet durable material that mimics wood while offering superior water resistance and dimensional stability.
Key Benefits:
Natural Wood Aesthetic - Perfect for decorative and architectural uses.
Waterproof & Moisture-Resistant - Closed-cell structure prevents swelling/cracking.
High Density (180-200 kg/m³) - Stronger than standard PU foams.
Easy to Mold - Suitable for complex shapes and intricate designs.
Long Shelf Life (12 months) - Stable storage performance.
