The current status of spray foam insulation technology
Polyurethane spray foam insulation materials have become the core technology of modern building energy-saving projects. With its excellent thermal insulation performance and seamless construction characteristics, it occupies an important position in the global building insulation market. This on-site forming technology sprays a mixture of isocyanate and polyol directly on the surface of the substrate, and reacts rapidly under the action of the catalyst to form a closed-cell or open-cell foam structure to achieve excellent insulation effect.
Closed-cell spray foam has become the preferred solution for insulation of building exterior walls, roofs and cold storage due to its excellent thermal insulation performance (thermal conductivity 0.020-0.028W/(m·K)) and structural reinforcement characteristics. The key to achieving this excellent performance lies in the precise control of the catalyst system for the trimerization reaction of polyisocyanurate.
Technical breakthrough of MXC-TMA catalyst
MXC-TMA catalyst is a new generation of trimerization catalyst developed specifically for spray foam. Its innovative formula solves many technical problems of traditional potassium-based catalysts during construction. This colorless to pale yellow transparent liquid product achieves precise control of polyurethane reaction kinetics through its unique chemical composition.
In terms of reaction control, MXC-TMA provides a more uniform and controllable rising curve, effectively reducing the sagging phenomenon during spraying construction. Its unique active components balance the foaming and gelling reactions, avoiding the generation of surface defects, while optimizing the curing speed and significantly shortening the construction interval time.
Improved fluidity is another major technical advantage of MXC-TMA. This product can significantly improve the flow characteristics of high-solid content formulas and achieve more uniform foam distribution, which is particularly suitable for spraying construction on complex geometric surfaces. Compared with traditional potassium-based catalysts, MXC-TMA can still maintain good reaction activity in low temperature environments, greatly expanding the temperature application range of construction.
Technical principles and performance advantages
MXC-TMA promotes the trimerization reaction of isocyanates to form a stable isocyanurate ring structure. This special chemical structure gives the foam material three core advantages: significantly improved thermal stability, the decomposition temperature can be increased by 30-50℃; excellent fire resistance, oxygen index can reach 26-28; excellent dimensional stability, volume change rate controlled within 1%.
In practical applications, we recommend the use of MXC-TMA in combination with amine catalysts, with the proportion controlled at 30-50% of the total catalyst. The product has a wide operating temperature range (15-35℃), is compatible with a variety of foaming agents such as HFC-245fa and HFO-1234ze, and can be used in conjunction with most polyether/polyester polyols and flame retardants.
