In the modern industrial landscape, Non-Flammable Polyurethane (PU) has evolved from a luxury specification to a mandatory regulatory requirement. As global urbanization intensifies, the demand for high-density fire-rated materials in high-rise construction, electric vehicle (EV) battery encapsulation, and aerospace insulation has skyrocketed. Wholesale buyers are no longer just looking for a sealant; they are seeking a comprehensive fire-safety ecosystem.
Saiqiang, based in Linyi City, Shandong Province, China, stands at the forefront of this evolution. By integrating intumescent technology with halogen-free flame retardants, we provide PU solutions that achieve B1 and B2 fire ratings under rigorous international standards. Our manufacturing philosophy bridges the gap between cost-efficiency and uncompromising safety.

Architects are shifting toward LEED-certified and fire-rated PU foams to lower insurance premiums and ensure occupant safety. High-rise buildings require "Non-Flammable" certification (ASTM E84 or EN 13501) for all building envelope materials.
The automotive industry is a major driver for fire-retardant PU. Thermal runaway protection in Lithium-ion batteries requires lightweight, non-conductive, and flame-retardant potting compounds to prevent catastrophic failures.
With the rise of global pharmaceutical and food delivery, fire-safe insulation in refrigerated warehouses is critical. Non-flammable PU panels prevent flashover fires in high-oxygen environments.
Our R&D focuses on the "Zero-Halogen" technical route. Traditional fire retardants relied on brominated chemicals, which are now restricted under REACH and RoHS due to toxicity. Saiqiang is pioneering:
Looking toward 2030, we are exploring Self-Extinguishing Nanocomposites that offer higher thermal stability without compromising the elasticity of the polyurethane matrix.
Shanghai Saiqiang Chemical Co., Ltd. was established in 2005, committed to silicone rubber, foam rubber research and development, production and sales. Our production base in Songjiang District, Shanghai, covers more than 100 acres with 26 advanced filling production lines.
ISO 9001:2015 certification ensures precise control throughout the entire process, from raw material inspection to final product dispatch.
China's Ten-Ring Certification, France's A+ Indoor Air Safety Certification, and a steadfast commitment to sustainability.
CE, ROHS, and REACH certifications fully meet the stringent market access requirements in Europe and North America.
Our products have successfully entered the markets of Europe, North America, and Southeast Asia. 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 for its global partners.
We provide a "Technology Empowerment Plan" for our wholesale distributors, which includes free material compatibility testing, joint R&D laboratory access, and site-specific application training. This ensures that the Non-Flammable Polyurethane purchased is perfectly suited for the specific climate and substrate conditions of the destination country.
Strong weather resistance suitable for curtain walls, doors, windows, and high-temperature scenarios. Advanced UV stability for extreme climates.
Highly efficient filling and insulation, widely used in construction and pipeline engineering with fire-retardant additives.
A traceless load-bearing solution that meets the eco-friendly needs of modern home decoration and modular construction.
B1 is "difficult to ignite" (Flame Retardant), while B2 is "normal flammability" but contains fire-suppressant additives that cause the foam to self-extinguish when the flame source is removed. For wholesale procurement in high-rise construction, B1 is usually required.
Yes, our specific formulations are designed for temperature ranges from -40°C to +90°C. However, the application surface should be free of frost for optimal bonding.
We utilize an automated DCS (Distributed Control System) that monitors chemical ratios in real-time across our 26 filling lines, ensuring every can meets the TDS (Technical Data Sheet) specifications.
Yes, our products are tested to meet various international standards including ASTM E84, UL 94, and EN 1366-4 for fire resistance duration.
Adhere to the principle of integrity as the foundation, abiding by laws and established long-term mutual trust relationships.
We encourage employees to actively innovate, developing new technologies like the Saiqiang 136 series.
Prioritizing stability and reliability, providing customers with high-quality adhesive industry solutions.
Centric to your needs, providing personalized services and support that strive to exceed expectations.
