Low Formaldehyde Melamine Foam

In the field of sound absorption applications, especially in many projects that need to use melamine foam exposed to the air, the formaldehyde emission of the material must reach the E1 level (≤1.5 mg/L), while most of the melamine foam currently produced in China can only reach the E2 level (≤3.0 mg/L).

In order to cope with this situation, Kangerna company launched 3 low-formaldehyde melamine foam models in 2022, with formaldehyde emission reaching the E1 level, thus meeting the requirements of most sound absorption projects.

Kangerna company reduces the formaldehyde emission of melamine foam while retaining other excellent properties of melamine foam such as sound absorption, heat insulation, flame retardancy, and ultra-lightweight, etc.

                                             
Functional Positioning for Environmental Safety and Acoustic Applications
Low formaldehyde melamine foam by our company is engineered for professional use requiring stringent indoor air quality, targeting sectors such as building insulation, acoustic panel manufacturers, and safety-critical constructions. Our material addresses the growing demand for low-emission core substrates by maintaining E1 formaldehyde emission levels (≤1.5 mg/L). This ensures compliance with environmental regulations and safer installations in commercial and institutional environments where both sound attenuation and reduced VOC levels are critical. The availability of various white and grey melamine foam block sizes facilitates integration across systems requiring precise dimensional adaptability. Our melamine foam sheets thus serve as essential components for environmentally focused engineering projects.

Technical Features and Measurable Engineering Parameters
This low formaldehyde foam is characterized by densities ranging from 8.0 to 8.4 kg/m³ and tensile strengths between 85 and 110 kPa, ensuring structural resilience within acoustic and insulation assemblies. With thermal conductivity values under 0.35 W/m·K and a wide service temperature range from –200°C to +240°C, the material is suitable for applications demanding both thermal performance and flame retardancy, evidenced by its B1 and UL94-V0 certifications. The product’s indentation hardness range supports durability under compression loads typical in panel construction. Available in regular blocks and maximum sheets of up to 2500x1250 mm, this foam facilitates streamlined production workflows for sound absorption modules and thermal insulation systems while adhering to safety and environmental benchmarks.

Industry Applications Supported by Compliance and Versatility
Our low formaldehyde melamine foam sheets find extensive use in acoustic panel fabrication for studios, classrooms, and offices where sound quality and indoor air purity are paramount. Additionally, its flame-retardant certifications and ultralight weight permit deployment in thermal insulation within building envelopes and safety-critical panels, ensuring compliance with fire safety codes. The foam’s combination of lightweight properties and low-emission formulation supports integration into modular systems and noise-control enclosures, enhancing both installation efficiency and occupant safety. Furthermore, its adaptability enables engineering prototypes for consumer electronics enclosures and green building projects focusing on eco-compliant insulation materials, reinforcing its role as a high-value component in diverse industrial contexts.


Product Advantages

Structural and Design Advantages of Low Emission Foam Core
The melamine foam sheets incorporate an optimized polymer network that balances ultralight density and mechanical integrity, tailored for demanding structural acoustics and insulation designs. The product’s modular block and sheet formats accommodate diverse manufacturing lines, facilitating seamless integration into existing foam processing systems. Our partnership with leading melamine foam manufacturers ensures consistent material quality and controlled formaldehyde emissions, reinforcing supply stability. The dual color options (white and grey) also provide flexibility in aesthetic-driven panel designs or labeling distinctions within production. Collectively, these design considerations maximize adaptability while promoting alignment with engineering standards for noise and thermal management components.

Performance Benefits and Enhanced Usability in Engineering Implementations
Low formaldehyde melamine foam sheets offer consistent thermal insulation efficacy combined with sound absorption capacity, critical for achieving compliance with regulatory thresholds regarding occupant comfort and safety. The foam’s E1 emission level enables use in sensitive indoor environments without compromising system performance, reducing potential health concerns associated with volatile organic compounds. Ease of cutting and handling due to the foam’s lightweight nature enhances manufacturing throughput and reduces installation labor costs. Furthermore, the product's certifications (B1 flame retardant, UL94-V0) support usage in fire-sensitive applications where adherence to strict safety codes is non-negotiable. This combination of reliable performance characteristics and environmental safeguards adds measurable value to engineering projects requiring sustainable core materials.
