1. Meeting Industry Needs, Developing New Environmental Materials

With the rapid development of industrial and energy industries, scenarios such as oil-water separation and oil spill cleanup have put forward higher requirements for oil-absorbing materials. Traditional oil-absorbing materials often have limited oil absorption efficiency, are difficult to reuse, and easily cause secondary pollution after disposal. Against the backdrop of increasingly strict environmental protection requirements, their shortcomings have become increasingly prominent. At the same time, emerging fields such as energy storage, new energy vehicles, and aerospace have continued to increase demand for composite materials that combine flame retardancy, thermal insulation, sound insulation, and oil absorption functions, putting forward higher standards for material research and development.

In response to this industry pain point, relying on many years of research, development, and production experience in the field of foam materials, Junhua has focused on the synergistic optimization of hydrophobic modification and oil absorption performance, and successfully developed hydrophobic melamine foam. From the very beginning of the project, the product has set high efficiency, safety, and environmental protection as its research and development goals, striving to minimize the environmental impact of the material throughout its lifecycle while meeting functional requirements.

The material adopts a unique nanostructure hydrophobic coating process. While maintaining the excellent basic performance of melamine foam, it achieves differentiated characteristics of selective oil absorption and active water repulsion. It can efficiently lock oil and block water intrusion in oil-water mixed environments, and is widely used in scenarios such as offshore oil spill cleanup, industrial leak treatment, and wastewater treatment. At the same time, the product completely retains the thermal insulation and sound insulation characteristics of standard melamine foam, making it have broad application space in multiple industrial fields. From the perspective of material mechanism, the hydrophobic coating builds a stable low surface energy structure on the material surface, making oil substances easy to adhere to and be absorbed, while water molecules are naturally blocked due to differences in surface tension, thereby achieving efficient oil-water separation. This design not only leverages the core function of oil-absorbing materials, but also takes into account the safety and durability of the material itself, reflecting Junhua's technical accumulation in material structure design and surface modification. It is worth mentioning that the combination of open-cell structure and hydrophobic coating enables the material to maintain stable flame retardancy and heat resistance while maintaining high porosity, laying a solid foundation for subsequent multi-scenario applications.

2. Multiple Core Performance, Balancing Efficiency and Safety

(1) Strong Oil Absorption and Excellent Hydrophobicity. Tests have shown that the product's oil absorption can reach up to 145 grams of oil substances per gram of material, with a water contact angle of approximately 146°. The hydrophobic performance is outstanding, enabling efficient separation in oil-water systems and providing reliable support for rapid oil stain removal. A higher oil absorption ratio means that more oil pollution can be treated with the same amount of material, thereby effectively improving the efficiency of emergency response and industrial treatment.

(2) Reusable, Economical and Environmental. The material can be recycled 10 to 12 times, during which it can still maintain about 90% of its oil absorption efficiency, effectively reducing single-use costs and waste generation, in line with the concept of sustainable development. Compared with disposable oil-absorbing materials, the recyclable characteristics of this product have obvious economic advantages in long-term operations, and also significantly reduce the pressure of waste disposal, helping enterprises achieve the unity of economic benefits and environmental benefits.

(3) Flame Retardant and Heat Resistant, Suitable for High-Temperature Scenarios. The product has good flame retardant properties and can operate stably for a long time in high-temperature conditions within 380°C, making it suitable for fields with high safety requirements such as energy storage, automobiles, and aerospace. Even under extreme high-temperature conditions, the material can still maintain the stability of its structure and function, providing reliable safety guarantees for related applications, and also significantly expanding the application boundaries of the product.

(4) Sound Absorption and Thermal Insulation, Comprehensive Performance. The material retains the excellent sound absorption performance of melamine foam, with a Noise Reduction Coefficient NRC ≥ 0.85, while also having good thermal insulation capabilities, with a thermal conductivity of ≤ 0.035 W/(m·K), which can meet the comprehensive protection needs of multiple scenarios. While taking into account the oil absorption function, its acoustic and thermal properties make the product show stronger applicability under complex working conditions, achieving the value of one material for multiple uses.

(5) Green and Non-toxic, Environmentally Friendly. Low formaldehyde, low VOC, certified by RoHS and REACH, in line with global sustainable development orientation, can be safely used in occasions closely related to the human body and the environment. Under the trend of continuously tightening environmental protection regulations, the green attributes of the material make it more competitive in domestic and foreign markets, and also easier to meet strict environmental access requirements.
