CCEWOOL® Ultra-thin PCW Blanket 3mm

CCEWOOL® Ultra-thin Polycrystalline Wool Fiber Blanket 3mm revolutionizes thermal protection and safety for new energy vehicle batteries.
In EV battery systems and high-temperature equipment, insulation materials are under more pressure than ever - they must deliver exceptional thermal efficiency in tight, complex spaces while withstanding impact, vibration, and prolonged high heat.

CCEWOOL® has pushed beyond the limits to create a 3mm Polycrystalline Fiber Blanket engineered for the most demanding applications:
• Precision Heat Shield - Fits seamlessly between battery cells to block thermal transfer.
• Thermal Runaway Containment - Lines module walls to prevent heat spread.
• Lightweight & Flexible - Perfect for complex, space-limited designs.
• Extreme Stability - Withstands frequent cycling and sudden high-temperature shocks.

Now available in a 3 - 25mm full thickness range, CCEWOOL® Polycrystalline Fiber Blankets meet the needs of EV systems, precision components, and advanced high-temperature equipment. This 3mm innovation is more than a product - it’s a leap forward in high-end insulation technology.

Benefits

  • Space-Saving Design

    Ultra-thin 3mm thickness, engineered specifically for EV battery systems and other confined spaces.

  • Extremely Low Shrinkage

    Maintains flexibility and stable structure even under long-term exposure at 1600℃.

  • Lightweight & Easy Installation

    Reduces equipment load, easy to cut and fit, ideal for complex geometries.

  • Ultimate Stability

    Withstands frequent thermal cycling and sudden high-temperature shocks.

Features of Ultra-thin PCW Blanket 3mm

  • Ultra-Thin High Performance

    Despite being only 3mm thick, retains resistance to temperatures up to 1600℃ (2912℉).

  • Ultra-Low Thermal Conductivity

    Almost free of shot content, delivering thermal efficiency superior to traditional refractories.

  • High Strength & Flexibility

    Exceptional tensile strength, uniform fiber diameter, resists mechanical impact and vibration.

  • Excellent Thermal Stability

    Dimensional stability under frequent heat cycling and extreme thermal shock, with minimal shrinkage.

  • Chemical Stability

    Resistant to acid and alkali corrosion, maintaining integrity in oxidative, reductive, and corrosive environments.

Application of Ultra-thin PCW Blanket 3mm

Highly efficient energy-saving solutions

EV Battery Systems

Cell-to-Cell Thermal Barriers: At just 3mm thickness, creates an effective heat shield in compact spaces, preventing thermal runaway propagation.

Module Wall Protection: Serves as a protective layer to stop heat from spreading when localized battery cells overheat.

Battery Pack Bottom Insulation: Enhances vehicle safety by resisting external impact or thermal radiation.
