Engineered for excellence, trusted by professionals worldwide.
In the contemporary landscape of sustainable construction and industrial efficiency, Polyurethane (PU) Foam Sealant has transitioned from a simple "gap filler" to a critical component of energy-saving building envelopes. As a premier polyurethane foam sealant manufacturer, Saiqiang Global recognizes the shifting macro-economic trends where carbon neutrality and thermal efficiency are paramount.
The global PU foam market is currently driven by the increasing demand for R-value thermal resistance. In North America and Europe, stringent energy codes (such as the EU Energy Performance of Buildings Directive) have mandated the use of high-performance sealants to eliminate "thermal bridges." Our products are formulated to meet these rigorous standards, offering industry-leading expansion rates and long-term dimensional stability.

Closed-cell PU foam, which Saiqiang specializes in, has cells that are completely sealed. This makes the foam denser and more effective as a water and air barrier, offering a higher R-value for thermal insulation compared to open-cell alternatives.
Our ISO 9001:2015 certified production lines in Shanghai use automated filling systems with precise weight and pressure control. Every batch undergoes rigorous testing for expansion rate, curing time, and bond strength before shipment.
Yes. Our sealants meet France's A+ Indoor Air Safety Certification and REACH compliance, ensuring they are safe for indoor use and meet strict environmental guidelines for the EU market.
Absolutely. With an annual output of 50,000 tons and dedicated R&D labs, we offer customized OEM/ODM services, including specific expansion ratios, fire ratings (Class B1/B2), and customized packaging sizes.
