Formulated for exceptional weather resistance, structural strength, and high-temperature tolerance. Ideal for curtain walls, high-rise fenestration, expansion joints, and passive fire barrier installations.
High-expansion structural foam offering superior thermal insulation, sound dampening, and gap-filling performance. Extensively applied in critical pipeline penetration sealing and window frame voids.
An innovative load-bearing adhesive designed for modern interior decoration, green building builds, and rapid mounting. Ensures zero-trace fixation with minimal VOC emissions.
In modern architectural engineering, passive fire protection (PFP) has shifted from a regulatory compliance checklist to a critical aspect of structural engineering design. As urbanization drives the development of complex high-rise commercial spaces, deep underground transits, and massive industrial processing units, containment of smoke, fire, and toxic fumes is vital for saving lives. Fire-rated silicone sealants act as crucial joint-sealing materials that preserve the compartmentalization integrity of walls, floors, and utility penetrations.
Traditional fire barriers relied on dense, rigid mortars or mineral wool packing. However, modern structures undergo constant thermal expansion, structural shifting, wind-load stresses, and seismic activity. This demands sealants that combine high fire resistance with elastomeric elasticity. Neutral-curing silicone systems have emerged as the industry gold standard due to their inorganic backbone, which naturally resists degradation under both atmospheric weathering and intense thermal radiation.
Global procurement offices and engineering companies are now enforcing stricter chemical criteria for import and installation. Key market requirements include:
Saiqiang operates state-of-the-art production environments compliant with the stringent testing specifications of diverse international markets.
ISO 9001:2015 certification ensures precise control, tracking, and process validation throughout raw material sourcing, polymerization, packaging, and final dispatch.
Compliance with China's Ten-Ring Ecolabel and France's A+ Indoor Air Safety Certification guarantees safe applications inside enclosed residential and public spaces.
Fully compliant with CE (EN 15651), ROHS, and REACH protocols, facilitating seamless integration into major European construction networks.
Provides robust dynamic sealing between external glass panels, aluminum mullions, and perimeter fire barriers. Withstands high wind shear and UV radiation while preventing fire spread between floors.
Effectively seals structural openings around mechanical, electrical, and plumbing (MEP) installations. Under high temperatures, our specialty sealants form a protective ash structure that keeps gas and flames contained.
Designed for critical structural floor-to-floor and wall-to-wall expansion joints. Accommodates high movement capacities (up to ±50%) without rupture, loss of adhesion, or compromised fire safety integrity.
Our laboratory is currently spearheading the development of next-generation silane-modified polymers (SMP) and hybrid intumescent formulations. Our technical goals target three primary fronts:
Building long-term relationships through integrity, technical innovation, and exceptional customer service.
We adhere to strict transparency, compliance, and ethical business codes to build reliable, long-term partnerships with our global clientele.
Our engineers actively develop new formulas and processes to meet evolving safety requirements and shifting market needs.
We maintain strict quality control throughout manufacturing to ensure the consistent batch-to-batch reliability of our structural adhesives.
We provide tailormade services, custom packaging options, and support to exceed project specifications and client expectations.
We support a collaborative workspace, helping our teams grow together to provide professional support to our international partners.
