Fluorosilicone Release Liners for EV & Automotive Bonding
Engineered to hold under heat and vibration — stable, reliable release for EV battery-module sealing, insulation, cell-bonding, and exterior-trim tapes, qualified for the long-term demands of automotive assembly.
Automotive and EV bonding puts release liners under real stress — heat, vibration, and high line speeds. Jefluo fluorosilicone liners are built to hold release consistent and dimensions stable through all of it, so battery-module assembly and converting stay predictable and contamination-free from first article to full production.
Key Benefits
Clean Release for Silicone PSA Applications
Fluorosilicone liners provide ultra-low release force for high-tack silicone adhesives used in EV battery pads, EMI shielding, and gasket constructions.
Stable Performance Under Heat and Pressure
PET-based liners withstand elevated temperatures, web tension, and lamination pressure without curling or adhesive distortion.
Compatible with High-Speed Converting Processes
Designed for slitting, die-cutting, and kiss-cutting at industrial speeds. Ensures dimensional stability during converting and precise release control.
Prevents Silicone Migration or Adhesive Contamination
Fluorosilicone coatings form a contamination-resistant barrier—critical for multilayer constructions, insulation films, and adhesive die-cuts.
Custom Release Levels and Substrate Options
Available in multiple release force levels and PET thicknesses to match adhesive tack and converting method.
Applications

Fluorosilicone Release Liner Configurations for Automotive & EV Components
Representative release-force configurations across automotive and EV bonding applications. Final specifications are tailored to each customer’s process and application.
Release Force | Substrate | Key Features |
|---|---|---|
Ultra Low (<3 g/in) | PET | Suited to EV battery insulation and flame-retardant silicone adhesive pads. Ultra-clean release without adhesive lift or distortion during die-cutting and lamination. |
Low (3~10 g/in) | PET | Suited to cell-bonding tapes and assembly films in EV battery modules. Smooth converting and reliable placement during high-speed processing. |
Moderate (10–30 g/in) | PET | Suited to silicone foam gaskets, sealing, and vibration-damping pads. Curl resistance and stable release during kiss-cutting and multi-layer converting. |
Heavy (>30 g/in) | PET | Suited to weather-resistant exterior bonding and strong structural tapes. Maintains reliable release under weathering, thermal cycling, and mechanical stress. |
Frequently Asked Questions
No. Our fluorosilicone release liners are engineered to minimize silicone migration and surface contamination, helping preserve adhesive integrity after lamination, heat curing, or high-pressure bonding. This ensures strong and stable adhesion in battery insulation pads, structural tapes, and sensor modules.
Yes. PET-based fluorosilicone liners maintain dimensional stability during high-speed kiss-cutting, slitting, and laser die-cutting without tearing or edge curling. This supports clean separation and tight-tolerance parts for EMI shielding, foam gaskets, and vibration-damping components.
PET-based fluorosilicone liners maintain dimensional stability and release consistency under elevated temperatures. They are suitable for EV battery insulation tapes and heat-cured adhesive systems where thermal cycling and sustained heat exposure are part of the application environment.
For silicone adhesive tapes used in EV battery modules, release force typically falls in the low to moderate range — 3–30 g/in depending on adhesive tack, application method, and whether manual or automated liner removal is used. Ultra-low release configurations are available for high-tack thermal interface adhesives where clean separation without adhesive distortion is critical.
