Flame-Retardant EVA Foam Board - Thermal Insulation & Fireproof Material for Prismatic Battery Cell Spacers

Product Overview

Our fire-retardant EVA foam board is a high-performance functional material specially designed for square shell battery spacing, insulation, and protection. Made of high-quality EVA plastic and resin, it features excellent flexibility, rubber-like elasticity, and can maintain good flexibility even at -50℃. With a closed-cell structure, it integrates fire retardancy, thermal insulation, shock absorption, and corrosion resistance, and is widely used in new energy square shell batteries, electrical appliances, precision instruments, automotive electronic parts, and other fields. It supports custom sizes and shapes, fully meeting diverse procurement needs.

• Fire Retardant Performance: Complies with UL 94-HB flame retardant standard, flame extinguishes immediately after removing the ignition source, effectively preventing fire spread and ensuring use safety.
• Excellent Flexibility & Low-Temperature Resistance: Rubber-like elasticity, good flexibility even at -50℃, not easy to break, suitable for harsh working environments.
• Waterproof & Corrosion Resistant: Closed-cell structure, no water absorption, moisture-proof; resistant to seawater, oil, acid, alkali and other chemicals, antibacterial, non-toxic, odorless and pollution-free.
• Anti-Slip & Shock Absorption: High resilience, tension and toughness, good shockproof and buffer performance, effectively protecting square shell batteries and precision components from impact damage.

Widely used in various fields, focusing on square shell battery protection and other scenarios:

• New energy square shell battery: Spacing, insulation, shock absorption and protection, preventing battery collision and damage
