In the modern architectural and industrial landscape, safety is not just a requirement; it is a fundamental benchmark of quality. As a premier China Fireproof Polyurethane Manufacturer, Saiqiang (SQ Adhesive) has spent decades perfecting the chemical synergy between high-efficiency insulation and rigid fire safety standards. Fireproof polyurethane (PU) foam has evolved from a simple gap-filler into a sophisticated thermal barrier capable of withstanding extreme temperatures and preventing the spread of combustion in residential, commercial, and industrial structures.
The "Information Gain" in today's market lies in understanding the chemical transition from standard PU to B1 and B2 grade flame-retardant variants. Unlike traditional adhesives, our fire-rated polyurethane solutions incorporate phosphorus-based or nitrogen-based flame retardants that create an "intumescent" layer when exposed to heat. This carbonized layer acts as a shield, cutting off oxygen and heat transfer, which is critical for high-rise building insulation and EV battery thermal management.
Located in the heart of China's industrial hubs (Linyi and Shanghai), we leverage local raw material accessibility to reduce costs while maintaining 100% quality control from monomer to finished foam.
Our collaboration with chemical engineering universities allows us to pioneer low-GWP (Global Warming Potential) blowing agents, ensuring our fireproof foam meets the strictest environmental mandates like EU REACH and ROHS.
Saiqiang's fireproof polyurethane is tested against DIN 4102-1 and EN 13501-1 standards, ensuring reliable performance in fire-rated door frames, HVAC systems, and curtain wall joints.
Filling expansion joints with fire-rated foam prevents the "chimney effect" during a fire, significantly increasing evacuation time for occupants.
Combining R-value efficiency with flame retardancy is essential for refrigerated warehouses where chemical safety and thermal insulation are equally paramount.
We provide specialized fluorosilicone and polyurethane coatings for battery packs to provide thermal runaway protection, a burgeoning sector for China manufacturers.
Based in Junan County, Linyi City, Shandong Province, China, Saiqiang is a leading adhesive manufacturer in Asia. We deliver innovative adhesive solutions to 62 countries worldwide, boasting a robust daily production capacity of 200,000 units. Driven by a steadfast commitment to strict quality management and environmental sustainability, Saiqiang has earned its reputation as a trusted partner across the construction, home decoration, and industrial sectors.
ISO 9001:2015 certification ensures precise control throughout the entire process.
China's Ten-Ring Certification, France's A+ Indoor Air Safety Certification.
CE, ROHS and REACH certifications fully meet the market access requirements in Europe.
"Since 2005, Shanghai Saiqiang Chemical Co., Ltd. has committed to silicone rubber and foam rubber research, covering 100 acres with 26 advanced filling lines."
The industry is moving toward bio-based polyols derived from castor oil or soy, reducing the petroleum footprint of polyurethane manufacturing.
New "Direct-to-Void" dispensing technologies are minimizing waste, a crucial factor for large-scale global procurement and cost efficiency.
China's "Double Carbon" goal is driving manufacturers to adopt solar-powered production lines and recycled packaging for adhesive cartridges.
B1 is classified as "difficult to ignite," offering the highest level of flame retardancy for construction foams. B2 is "normally flammable" but contains retardants that prevent rapid flame spread. Most international building codes for high-rises require B1 rating.
Yes, as a leading factory, Saiqiang offers full OEM/ODM services. We can adjust viscosity, expansion ratio, and fire-rating levels to meet specific regional building regulations or industrial requirements.
Our foam products typically have a shelf life of 12-15 months when stored in a cool, dry place. The stability of our formula ensures the flame-retardant chemicals do not settle over time.
We adhere strictly to REACH and ROHS standards. Our products are CFC-free and use blowing agents with zero ODP (Ozone Depletion Potential), ensuring they are safe for indoor air quality as certified by the French A+ rating.
At Saiqiang, we believe in Innovation-Driven growth. We encourage employees to actively develop new technologies to meet the constantly changing market demands. Our Quality First principle ensures the stability and reliability of every cartridge of adhesive that leaves our factory.
