MF-MH

MF-MH Series Hydrophobic Melamine Foam — Professional Waterproofing Solution

Product Overview

The MF-MH series is a high-performance material engineered through specialized post-treatment processes (e.g., surface hydrophobic modification or impregnation) to endow conventional melamine foam with durable waterproofing capabilities. This treatment forms a stable hydrophobic layer (similar to a Teflon effect) on the foam surface, effectively repelling water molecules while retaining inherent properties such as exceptional flame retardancy, lightweight flexibility, and eco-friendly safety. Designed for demanding waterproofing applications.

Key Features

  1. Exceptional Hydrophobicity: Hydrophobicity rate ≥98%, with a large water contact angle; water droplets bead up and roll off the surface, minimizing penetration.
  2. High Flame Retardancy: UL94 V-0 certification, self-extinguishing, no molten dripping.
  3. Stable Physical Performance: Wide operating temperature range (-240°C to +220°C), strong weather resistance.
  4. Safety and Environmental Compliance: Meets RoHS/REACH regulations, free of harmful substances.

Typical Applications

  • Waterproof Insulation for Power Batteries: Inter-cell spacers and shell sealing pads in battery packs to prevent short circuits caused by moisture ingress.
  • Outdoor Apparel and Equipment: Waterproof, breathable, and thermal insulation layers in jackets and ski suits, offering lightweight warmth.
  • Ventilation Systems and Ducts: Waterproof, moisture-proof, and thermal insulation layers for HVAC and automotive ducts, preventing condensation buildup.
  • Electronic Device Protection: Moisture-proof pads and sealing gaskets for precision instruments and junction boxes, safeguarding circuits from water damage.
  • Marine and Offshore Equipment: Thermal and acoustic insulation for ship cabins and waterproofing for offshore platforms, resisting high-humidity and salt-spray environments.

Why Choose MF-MH Series?​

The MF-MH series combines the multiple properties of melamine foam with reliable, durable waterproofing, addressing the weakness of traditional foam in humid environments. If you seek a high-performance material that integrates waterproofing, flame retardancy, thermal insulation, and environmental safety, the MF-MH series is your ideal choice.
