Hydrophobic Melamine Foam

Kangerna® hydrophobic melamine foam is a modified melamine foam with a hydrophobicity of up to 98%. It also has the conventional properties of melamine foam such as sound absorption, heat insulation, and flame retardancy.


Targeted Solutions for Moisture-Resilient Applications
Hydrophobic Melamine Foam is engineered for industries requiring materials that combine high water repellency with the inherent properties of melamine foam. Primarily designed for manufacturers and engineers in acoustics, thermal insulation, and cleaning product sectors, this foam supports applications exposed to moisture and liquids. Its hydrophobic rate of 98% ensures durability where conventional melamine foam might degrade. Leading melamine foam manufacturers supply this product in KS12 and KS22 variants, facilitating integration into moisture-sensitive manufacturing processes and prototyping systems requiring stable, moisture-resistant foam sheets.

Technical Specifications Highlighting Reliability
This hydrophobic melamine foam exhibits a density of 7.5 ± 1.5 kg/m³ and thermal conductivity below 0.35 W/m.k, confirming its efficiency in heat insulation without weight penalties. Its dimensional stability tolerates temperatures from -200℃ up to +240℃, supporting applications in extreme environments. Flame-retardant classifications including GB8624-2012 B1 and UL94-2013 V0 ensure compliance with safety regulations. Sound absorption metrics reach NRC 0.9 for 80 mm thickness, further reinforcing its suitability for acoustic panels. Offered in large melamine foam sheets up to 2500×1200×50 mm, the product supports scalable industrial requirements with standardized consistency.

Industrial Applications Enhancing System Integration
The hydrophobic melamine foam is increasingly utilized in moisture-prone environments, such as manufacturing moisture-resistant cleaning sponges, thermal insulation components, and acoustic panels exposed to humidity. By combining moisture resistance with flame retardancy and sound absorption, it addresses multiple engineering challenges in product design and prototyping. Its compatibility with various industrial systems is proven across sectors including flame retardant insulation, packaging for sensitive goods, and specialized filtration. These characteristics enable process optimization and product reliability, positioning this foam as a core material for melamine foam suppliers targeting versatile industrial solutions.


Product Advantages

Structural Design and Material Engineering Benefits
The hydrophobic melamine foam features a low-density but structurally sound formula balancing weight and mechanical performance, crucial for integration into complex assemblies. Its large-format melamine foam sheets provide fabrication flexibility, reducing joints and installation time while maintaining uniform physical properties. The hydrophobic treatment applied by established melamine foam manufacturers ensures water repellency without compromising tensile strength or thermal insulation. This precise design supports component modularity and system adaptability in layered insulation or acoustic paneling applications requiring moisture protection and fire safety certifications.

Operational Performance and Engineering Value
With thermal conductivity rated at ≤0.35 W/m.k and sound absorption NRC values up to 0.9, this foam delivers measurable improvements in energy efficiency and noise reduction. Its wide operating temperature range supports deployment in extreme climate conditions, expanding the envelope for product design. Ease of fabrication into melamine foam sheets of various sizes expedites custom prototyping and volume production, facilitating workflow integration in manufacturing environments. The consistent hydrophobic rate above 98% ensures long-term durability against moisture ingress, adding value by reducing maintenance requirements and improving lifecycle cost management for end products.
