Melamine Foam for New Energy - Battery & EV Thermal Insulation
MeFoam Series Melamine Foam — The Preferred Material for Insulation and Buffering in Power Batteries
Dedicated to Ensuring Safety and Performance of Power Batteries
Product Introduction
The MeFoam series melamine foam is a novel polymer elastomer material produced by foaming melamine resin through advanced technology. This series of products, renowned for its exceptional flame retardancy, excellent cushioning resilience, and reliable insulation performance, has become a critical functional material inside modern power battery packs. It is widely used in applications such as inter-cell cushioning pads, battery module insulation, and top sealing cushioning for battery packs, providing essential protection to enhance the overall safety, stability, and service life of battery systems.
We are honored to supply high-performance MeFoam series products and solutions to China’s largest battery manufacturers (e.g., CATL).
Core Advantages
- Exceptional Flame Retardancy, Safe and Reliable: The product is UL94 V-0 certified, does not combust upon exposure to open flame, only slightly chars, effectively prevents thermal runaway propagation, and provides the highest level of safety protection for batteries.
- Excellent Cushioning and Compression Fatigue Resistance: Offers good elasticity and recovery, providing continuous and effective buffering for cell expansion/contraction during charge-discharge cycles. The extremely low permanent compression deformation rate ensures the product maintains its cushioning performance under long-term pressure.
- Outstanding Electrical Insulation: Extremely high volume and surface resistivity (≥10⁸ Ω), effectively preventing internal short circuits in batteries and ensuring stable operation of the circuit system.
- Environmental Friendliness and Chemical Stability: Free from harmful substances such as sulfites, compliant with environmental regulations like RoHS and REACH. Exhibits stable chemical properties and aging resistance.
- Lightweight and Efficient: The very low density enables lightweight design while delivering excellent performance, contributing to higher energy density in power batteries.
