Product Description

SDP1234 Water-Based Spray Rigid PU Foam - Lightweight, Fireproof, Thermal & Noise Insulation for Bus/Traffic Industry (Made in China)
SDP1234 Water-Based Spray Rigid PU Foam is a high-performance, lightweight insulation material designed for the traffic industry (buses, automotive, HVAC). It forms a seamless, airtight sealing layer that significantly reduces heat loss, noise, and vibration, enhancing passenger comfort. This open-cell flexible PU foam is engineered for superior thermal insulation (0.042 W/m·K), fire resistance (A-0 rating), and noise reduction, making it ideal for Middle Eastern and Asian markets with extreme climates.

Key Features & Benefits:

Lightweight & Durable - Core density <10 kg/m³ for easy application without structural burden.
Excellent Thermal Insulation - Low thermal conductivity (<0.042 W/m·K) for energy efficiency.
Fireproof & Safe - Complies with GB 8410-2006 (A-0 flammability rating) and low VOC emissions.
Noise Reduction - Open-cell structure absorbs sound, ideal for buses, automotive, and HVAC systems.
Strong Adhesion - Seamless spray application ensures airtight sealing with no gaps.
Eco-Friendly - Low formaldehyde (<10 mg/kg) and VOC emissions, meeting VDA275, DIN75201 standards.
