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.
In the modern landscape of high-rise construction and industrial safety, Fire Retardant Expanding Foam Sealant has evolved from a simple gap filler to a critical component of Passive Fire Protection (PFP). As a premier Chinese factory, we leverage advanced polyurethane chemistry to provide sealants that offer up to 240 minutes of fire resistance, effectively preventing the spread of flames, smoke, and toxic gases through structural voids.
Our fire retardant foams utilize intumescent chemical pathways. When exposed to heat, the material undergoes a chemical reaction that creates a carbonaceous char layer. This char acts as an insulating barrier, protecting the core of the sealant and the underlying substrate from thermal degradation.
Statistical data shows that smoke inhalation is the leading cause of death in building fires. Saiqiang's expanding foam provides a gas-tight seal that blocks lethal combustion byproducts (CO and HCN) from migrating between rooms via service penetrations.
Unlike rigid mortars, our PU foam sealants maintain elasticity. This is vital for "working joints" that experience thermal expansion or vibration, ensuring the fire seal remains intact even during seismic shifts or high-wind loads in skyscrapers.
In regions like Dubai or Shanghai, fire safety in curtain walls is paramount. Our sealants are used to fill "perimeter fire barriers" (the gap between the floor slab and the glass curtain wall), meeting stringent ASTM E2307 standards.
With the tightening of the UK Building Safety Act, homeowners and contractors require B1-rated foams for window and door frame installations to ensure compartmentalization in multi-occupancy buildings.
Data centers house high-density electronics prone to thermal runaway. Our fire-retardant foams are utilized in cable tray penetrations to prevent localized electrical fires from cascading across server halls.
In explosive environments, sealing conduits and control rooms against external fire threats is critical. Our specialized formulations resist hydrocarbons and provide long-term durability in harsh outdoor conditions.
Shanghai Saiqiang Chemical Co., Ltd. (established 2005) operates a state-of-the-art facility in Songjiang District. Our advantage lies in Vertical Integration:
Saiqiang is committed to the next generation of bonding technology, focusing on carbon neutrality and extreme performance.
Developing polyols derived from vegetable oils to reduce petroleum dependency by 30% by 2026.
Aiming for zero-emissions to meet Ultra-Low Energy building standards (Passive House).
Merging silicone's UV resistance with polyurethane's expansion power for outdoor fire sealing.
Implementing real-time batch testing via AI sensors to ensure 100% fire-rating consistency.
Ensures precise control throughout the entire manufacturing process, from raw material procurement to final batch testing.
Our products fully meet European market access requirements, ensuring they are free from harmful substances and safe for indoor use.
Certified for Indoor Air Safety, guaranteeing that our fire-retardant foams do not release toxic volatile organic compounds.
A: According to DIN 4102 standards, B1 is classified as "difficult to ignite" or flame retardant, whereas B2 is "normal flammability." Saiqiang’s B1 foam provides a much higher level of protection, suitable for public buildings and high-risk industrial zones.
A: While our PU foams have excellent adhesion, they are sensitive to UV light. For outdoor applications, we recommend covering the cured foam with a UV-resistant sealant (like our 998 Neutral Silicone) or painting it to ensure long-term structural integrity.
A: Our fire-rated foams are tested to provide up to 240 minutes (4 hours) of protection depending on the joint depth and width. Once cured, the chemical properties remain stable for the life of the building if not mechanically disturbed.
A: Yes. With 26 filling lines and a daily capacity of 200,000 units, we provide full OEM/ODM support, including custom formulations, tailored expansion ratios, and private brand packaging design.
