The global construction, aerospace, automotive, and heavy industries are experiencing unprecedented regulatory updates requiring strict fire-preventive strategies. Standard adhesives and gap fillers are no longer sufficient when high-risk infrastructure relies on complete fire containment. Modern building designs, especially in mega-cities and high-tech industrial parks, utilize passive fire protection (PFP) structural sealants to establish physical compartmentalization, preventing the spread of smoke, toxic gases, and open flames.
Core Growth Insight: Increased adoption of rigid building regulations—such as the International Building Code (IBC) in North America, EN Eurocodes in the European Union, and GB Standards in Asia—has converted passive fire protection from a selective optimization into an absolute mandate. The global fire rated adhesive market is expected to expand rapidly, driven by the integration of advanced polymers like intumescent polyurethanes, high-temperature silicones, and specialized fluorosilicone coatings.
Multi-story commercial properties require curtain wall interfaces and joint networks that can withstand temperatures above 1,000°C. Factory-engineered sealants prevent continuous flame propagation through thermal expansion, filling voids before the fire bypasses structural partitions.
Under heat exposure, next-generation intumescent formulas swell to multiple times their dry state thickness, generating a dense, fire-resistant carbonaceous layer. This barrier acts as a thermal insulation shield for internal structural components.
All safety-critical operations necessitate verifiable certifications. Saiqiang ensures global adherence through systematic audits validating compliance under ISO 9001:2015, CE EN15651, France A+ Indoor Air Safety, and RoHS/REACH guidelines.

Our dedicated production base, located in Sijing Industrial Park, Songjiang District, Shanghai, spans more than 100 acres and operates 26 automated filling production lines. Together with dynamic material warehouses, packaging depots, and finished product yards, our annual output exceeds 50,000 tons.
To support high-volume international demand, we have expanded our regional manufacturing systems. Based in Junan County, Linyi City, Shandong Province, China, Saiqiang serves architectural and industrial distribution networks across 62 countries, delivering a maximum daily capacity of 200,000 units. From structural glazing sealants to eco-friendly nail-free formulas, Saiqiang represents reliability and performance.
We work to align our manufacturing stages with demanding global compliance frameworks. Our quality certifications include:
ISO 9001:2015 certification ensures precise control throughout the entire manufacturing process.

CE (EN15651), ROHS, and REACH certifications fully meet market access requirements across Europe.
Fire-rated adhesives are engineered materials that require high stability under severe chemical, mechanical, and thermal stresses. Our R&D team continuously refines formulations, focusing on the following chemical technologies:
Organosilicon polymers provide natural resistance to ultraviolet radiation, moisture, and temperature fluctuations. Saiqiang's neutral-cure silicone systems utilize non-corrosive crosslinkers designed for structural perimeter expansion joints. When exposed to fire, they form a robust silica crust (SiO2) that remains stable up to 1200°C without releasing halogenated gases.
Our polyurethane foam formulations incorporate phosphorus-nitrogen synergists and expandable graphite. In a fire, the polyurethane expands rapidly to fill the void, creating a dense char layer that blocks both heat and toxic smoke.
For applications requiring specialized thermal and electrical protection, our fluorosilicone rubber coatings combine the chemical resistance of fluorocarbons with the thermal stability of silicones. These systems offer high dielectric strength and thermal conductivity, helping protect battery packs and power electronics in harsh conditions.

| Wall Panel Adhesive | Synthetic Elastomer / MS Polymer | Flame-Retardant Option | Medium Elasticity | Integrated wallboard panels, cleanrooms, decorative panels |
Through our localized warehousing partners and overseas service teams, Saiqiang maintains active distribution channels across Europe, North America, and Southeast Asia. We are dedicated to providing low-carbon, high-performance bonding solutions, and we regularly participate in global industrial and chemical trade shows to coordinate with partners and display our latest innovations.
Curtain walls undergo continuous thermal expansion, structural sway, and wind-load stresses. Our structural silicone adhesives offer high elastic recovery and weather resistance, maintaining dynamic seals that double as fire and smoke barriers at slab edges.
Service penetrations present a vulnerability in building fire walls. By applying high-expansion polyurethane foams and neutral silicone sealants, contractors can seal gaps around electrical lines, water piping, and HVAC ductwork, keeping compartments airtight.
Automotive battery assemblies require fire-resistant sealants with high dielectric strength and chemical stability. Our high-performance fluorosilicone rubber coatings isolate thermal runaway events, protecting sensitive battery cells from cascading heat damage.
To support global builders and distributors, we offer our Technological Empowerment Program. Partners have access to:
One-component, high-volume fill polyurethane foam designed for standard building gap sealing and insulation.
High-expansion foam compound formulated for joint filling, acoustic deadening, and thermal insulation.
High-durability elastomer designed for exterior cladding joints, windows, and perimeter sealing.
High-performance, neutral-cure silicone sealant providing excellent weatherability and flexible support.
A genuine fire-rated sealant is designed and tested to prevent the passage of flame, hot gases, and heat through building joints or penetrations for a rated period (commonly 1 to 4 hours). This performance is verified by testing standards such as UL 2079 (tests for joint systems), ASTM E814 (tests for penetration firestops), and EN 1366. It must maintain adhesion and elastomeric properties under temperature loads that can exceed 1000°C.
Regular silicones are thermally stable up to around 150-200°C but will eventually combustion-degrade under direct flame exposure. Intumescent sealants contain active chemicals (like expandable graphite or mineral hydrides) that react at high temperatures (typically starting around 180°C). This reaction causes the sealant to expand to several times its original volume, forming a carbon char layer that protects the underlying structures.
Generally, one-component polyurethane foam (Class B1 or B2 under DIN 4102) is used to fill gaps, provide thermal insulation, and block drafts. However, for systems that require high structural fire ratings (such as critical wall joints or larger pipe openings), they should be paired with a dedicated firestop sealant or intumescent coating. This combination ensures structural integrity and limits fire spread.
We operate an ISO 9001:2015 quality management system, supported by 26 automated filling lines that minimize human error. Each batch of raw silicone polymers, polyurethane prepolymers, and crosslinkers undergoes viscosity, density, and cure-rate checks. We also perform regular internal and third-party fire testing to verify compliance with international standards.
Our formulas are developed with indoor air quality and worker safety in mind. We have earned China's Ten-Ring Ecolabel and France's A+ Indoor Air Safety Certification. Our products also meet European RoHS and REACH standards, verifying they are free from restricted chemical additives.
