Explore our top-tier factory direct silicone, polyurethane, and intumescent firestop solutions engineered for global compliance and extreme durability.
A comprehensive guide for EPC contractors, architectural engineers, and global wholesale buyers on passive fire containment, regulatory standards, and chemical formulations.
When exposed to temperatures exceeding 180°C, our specialized intumescent sealants undergo an endothermic chemical reaction, expanding up to 25–40 times their original volume. This rapid expansion creates a high-density, carbonaceous char barrier that seals structural voids, preventing heat transfer and fire spread for up to 4 hours (F-Rating & T-Rating compliance).
In building fires, smoke inhalation causes over 75% of casualties. Our elastomeric silicone firestop formulations maintain air-tight seals under extreme differential pressures, effectively blocking toxic combustion gases, halogenated acids, and volatile smoke particulate from migrating between fire zones (L-Rating compliance).
Commercial curtain walls and expansion joints experience severe thermal expansion, seismic shear, and wind load vibration. Our neutral cure fireproof silicone sealants provide ±50% joint movement capability without cracking, delamination, or loss of adhesion against glass, aluminum, concrete, and masonry.
Selecting the correct passive fire protection material requires deep knowledge of substrate compatibility, hourly fire endurance ratings, and environmental exposure conditions. Below is a technical summary of our wholesale commercial offerings:
| Polymer Chemistry | Fire Endurance Rating | Movement Capability | Primary Application Area | Standard Compliance |
|---|---|---|---|---|
| Intumescent Acrylic | 1 to 4 Hours | ±12.5% to ±25% | Internal penetrations, cable trays, metallic pipes, interior drywall joints | UL 1479, UL 2079, EN 1366-3 |
| Neutral Silicone Firestop | 2 to 4 Hours | ±25% to ±50% | External curtain wall perimeter, expansion joints, HVAC ducting, cleanrooms | ASTM E814, BS 476 Part 20, CE EN 15651 |
| Fire Retardant PU Foam | 1 to 2 Hours | ±10% | Door/window frame gap filling, acoustic insulation, void sealing | DIN 4102 B1/B2, EN 1366-4 |
| Hybrid Polyether Sealant | 2 to 3 Hours | ±35% | Precast concrete panels, subterranean infrastructure, damp surface bonding | ISO 11600, GB 23864 |
Shanghai Saiqiang Chemical Co., Ltd. was established in 2005, committed to silicone rubber and foam rubber research and development, production, and global commercial sales. Our headquarters production base is strategically located in Sijing Industrial Park, Songjiang District, Shanghai, covering an expanse of more than 100 acres. The facility features 26 advanced fully automated filling production lines, fully integrated with high-capacity solid raw material warehouses, specialized packaging material storage, and climate-controlled finished product logistics centers. With an annual production output exceeding 50,000 tons, Saiqiang stands as one of China's largest and most comprehensive adhesive manufacturing enterprises.
Expanding our industrial presence, our key manufacturing center in Junan County, Linyi City, Shandong Province, China positioning Saiqiang as a premier adhesive powerhouse in Asia. We deliver state-of-the-art adhesive and firestop solutions to 62 countries worldwide, maintaining a staggering daily capacity of 200,000 units. Driven by strict quality control protocols and sustainable practices, Saiqiang is recognized across commercial construction, high-end architectural decoration, and industrial assembly sectors.
Our rigorous testing and environmental compliance ensure seamless integration into international supply chains, meeting municipal fire codes and green building standards globally.
ISO 9001:2015 certification ensures precise control, raw material traceability, and batch consistency throughout the entire manufacturing process.
Certified under China's Ten-Ring Certification and France's A+ Indoor Air Safety Certification, guaranteeing ultra-low VOC emissions for safe indoor air quality.
Full CE, ROHS, and REACH compliance, enabling unrestricted commercial usage across European Union member states and North American construction jurisdictions.
Creating a new generation of healthy, fire-safe environments to enhance structural resilience and global quality of life.
Unlocking economies of scale, chemical formulation control, and reliable OEM/ODM contract manufacturing for large-scale distributors and engineering groups.
Located in Shandong and Shanghai chemical hubs, Saiqiang leverages direct access to high-purity silane monomers, silicone polymers, and specialized fire retardant additives, ensuring cost predictability and immunity to global raw material shocks.
We offer full-spectrum private label manufacturing. From custom cartridge printing (300ml cartridges, 590ml sausages) to specialized RAL color matching (fire red, concrete grey, clear, black), our joint R&D lab caters precisely to brand specifications.
With 26 automated high-speed filling lines, every cartridge undergoes online weight monitoring, viscosity testing, skin-over time verification, and bubble-free vacuum degasification to eliminate field failure risks.
From architectural curtain wall weatherproofing to specialized interior decorative bonding, Saiqiang delivers versatile solutions engineered for long-term reliability.
High expansion, thermal insulation, acoustic damping, and void filling for building gaps.
Single-component moisture curing polyurethane foam for window sash and perimeter sealing.
Neutral silicone sealant designed for superior weatherability in external building facades.
High modulus structural adhesive for glass curtain walls, metal panel bonding, and glazing.
Engineered for critical firestop penetrations and high-movement structural joints across commercial, civil, and industrial infrastructure projects.
In modern glass curtain wall towers, the gap between the edge of the concrete floor slab and the exterior facade (spandrel zone) acts as a chimney for vertical fire spread. Our neutral fire-rated silicone combined with mineral wool insulation provides a certified floor-to-wall perimeter fire barrier, accommodating thermal slab movement while maintaining smoke containment.
Mechanical, electrical, and plumbing (MEP) openings in fire-rated walls and floor assemblies require flexible intumescent sealing. When fire strikes, our sealant expands around metallic pipes, electrical conduit bundles, and cable trays, sealing off voids left by melted cable jackets and preventing lateral flame migration.
Data centers and pharmaceutical manufacturing units require airtight, non-outgassing, low-VOC fire barriers. Our low-odor, mold-resistant silicone sealant formulations prevent dust infiltration and fire propagation without releasing corrosive halogen gases that harm sensitive microelectronics.
Subjected to continuous moisture, vibrations, and severe air pressure fluctuations from passing trains, subway station expansion joints mandate high-elasticity, water-resistant fire sealants that retain mechanical adhesion under extreme ambient humidity.
