Hydrophobic Melamine Foam – Oil-Repellent & Reusable Absorption Solution

SINOYQX Hydrophobic Melamine Foam is an advanced open-cell, flame-retardant foam modified with a water-repellent surface. It combines oil selectivity, reusability, and insulation performance, making it a sustainable alternative to traditional absorbent and insulation materials.

With a unique nano-structured hydrophobic coating, this foam selectively absorbs oil while repelling water—perfect for oil-water separation, spill cleanup, and industrial filtration. At the same time, it retains the thermal and acoustic properties of standard melamine foam, ensuring broad applications across multiple industries.

Key Features & Benefits

🌊 Oil-Selective & Hydrophobic
Absorbs oil up to 145 g/g while resisting water penetration (contact angle ~146°).
♻️ Reusable & Cost-Effective
Maintains absorption capacity even after 10–12 reuse cycles, reducing waste and cost.
🔥 Flame-Retardant & Heat-Resistant
Safe for high-temperature applications, working stably up to 380 °C.
🔇 Acoustic & Thermal Insulation
Retains excellent sound absorption (NRC up to 0.85) and thermal insulation properties.
🌍 Eco-Friendly & Non-Toxic
Lightweight, formaldehyde-free, and recyclable—aligned with global sustainability goals.

Applications of Hydrophobic Melamine Foam

Oil Spill Cleanup & Environmental Protection
Rapid response material for marine oil spills, industrial leakage, and wastewater treatment.
Energy Storage & Battery Systems
Provides thermal insulation and prevents moisture absorption, ensuring safe operation in EV batteries and grid storage systems.
Automotive & Aerospace
Used in engine compartments, aircraft cabins, and EV vehicles for combined oil absorption, acoustic damping, and heat insulation.
Industrial Filtration
Effective in oil-water separation systems, refining, and petrochemical industries.
Construction & Architecture
Ideal for soundproofing walls, ceilings, HVAC ducts, and areas exposed to oil contamination.

Frequently Asked Questions (FAQs)

Q1: What makes hydrophobic melamine foam different from standard melamine foam?
A1: Standard melamine foam is water-absorptive, while hydrophobic melamine foam is modified to repel water but selectively absorb oil, making it ideal for oil-water separation.

Q2: How many times can the foam be reused?
A2: It can be reused 10–12 times with minimal loss of performance, offering cost savings and sustainability.

Q3: Is it safe for high-temperature environments?
A3: Yes, the foam maintains structure and function up to 380 °C, making it suitable for energy storage, automotive, and aerospace applications.
