As a leading Wholesale Fire Resistant Polyurethane Foam Manufacturer, Saiqiang (Based in Junan County, Linyi City, Shandong Province, China) recognizes that the global demand for safety-critical materials is at an all-time high. Fire resistant PU foam is no longer just a filling agent; it is a vital component in the Passive Fire Protection (PFP) strategy of modern architectural and industrial designs.
Our foam solutions meet B1 and B2 fire ratings according to DIN 4102 standards, ensuring that the material self-extinguishes upon removal of the flame source, significantly reducing smoke toxicity.
Beyond fire resistance, our PU foam provides superior thermal insulation (low lambda values), making it ideal for HVAC systems, cold storage, and energy-efficient building envelopes.
Meeting the strict demands of 62 countries, including EU REACH, RoHS, and CE certifications, we ensure your procurement process is frictionless and legally compliant.
With a daily production capacity of 200,000 units, Saiqiang leverages its 26 filling production lines and a 100-acre facility in Shanghai to serve as a reliable partner in the global supply chain. We don't just supply foam; we provide peace of mind through rigorous quality control (ISO 9001:2015).
Global procurement trends indicate a 15% year-on-year increase in the demand for fire-rated polyurethane foams in the Southeast Asian and North American markets. This is driven by stricter building codes and the rise of high-rise commercial structures.
Saiqiang's "Smart-Foam" technology incorporates nano-encapsulated flame retardants that remain stable for years, preventing the degradation of fire properties over time.
Transitioning from petroleum-based raw materials to castor oil and soybean-based polyols to reduce the carbon footprint by 30% while maintaining B1 fire ratings.
Implementing machine-learning sensors in our 26 filling lines to monitor chemical ratios in real-time, ensuring zero-defect production at a 50,000-ton annual output.
Developing the next generation of PU foams that release zero toxic gases during fire exposure, targeting high-specification aerospace and maritime applications.

We provide France A+ Indoor Air Safety Certification and REACH/RoHS compliance documents for every batch, ensuring safe entry into the European and North American markets.
Through localized warehousing and technical support teams, we ensure a rapid response to customer demands. Saiqiang continuously researches and develops low-carbon formulas, dedicated to providing safe and sustainable bonding technologies.
A: Under the DIN 4102 standard, B1 is defined as "difficult to ignite" or flame retardant, whereas B2 is "normally flammable." For high-risk industrial applications and public buildings, B1 is the preferred choice as it has a higher resistance to ignition and lower smoke emission.
A: We utilize 26 automated filling lines with integrated chemical monitoring. Every batch undergoes a flame-spread test and density verification in our joint R&D laboratory before shipment. We provide a Certificate of Analysis (COA) for every order.
A: Yes. We specialize in OEM/ODM solutions, offering customized expansion rates, curing times, and color variations. We also provide free material compatibility testing for your specific substrates.
A: Absolutely. Our products carry the China Ten-Ring Certification and French A+ Indoor Air Safety Certification, ensuring low VOC emissions and a healthy environment for building occupants.
A: Typically 9 to 12 months when stored in a cool, dry place. Our advanced valve design prevents gas leakage, ensuring the propellant remains effective throughout the shelf life.
