Product Description

Product Overview

The LXFP-256 Series is a liquid silicone foam elastomer specifically engineered for harsh industrial environments. Primarily used as sealing gaskets for electric vehicle (EV) battery packs, this product effectively reduces bumps and vibrations during vehicle operation while meeting the manufacturing demands of lightweighting, automation, and cost-efficiency.

Featuring excellent waterproof sealing, low specific gravity, high flame retardancy, and superior resistance to compression set, it wraps around the bottom or modules of power batteries to provide exceptional cushioning, anti-slip shock absorption, and thermal insulation. Lixing Composite Material provides rolls in various thicknesses, which can be precision die-cut into custom dimensions according to client requirements.

Core Features

• Outstanding Flame Retardancy & Environmental Compliance: Certified to UL94 V-0 flame rating, with toxic gas emissions compliant with the European railway standard EN45545-2 R10. Fully compliant with RoHS and REACH regulations.

• Excellent Thermal & Weather Resistance: Recommended for continuous operation from minus 55 degrees Celsius up to 200 degrees Celsius, and can withstand intermittent peak temperatures of 280 degrees Celsius. Offers superb resistance to UV and ozone.

• Fine and Uniform Cell Structure: Features a delicate, uniform pore structure with low water absorption (less than or equal to 5%), delivering premium waterproof, sealing, and thermal insulation benefits.

• High Fatigue & Creep Resistance: Highly adaptable to mechanical fatigue, maintaining low long-term compression set and excellent resistance to stress relaxation.

   

Primary Applications

• Waterproof sealing, shock absorption, and component protection for electric vehicle (EV/HEV) power battery PACKs.

• Buffering and thermal protection against cell expansion and contraction during charge/discharge cycles.

• Flame-retardant, thermal-insulating, and vibration-damping protection inside electronic enclosures and transportation equipment.
