FAQ
Fluorosilicone release liners are specialty liners coated with a fluorosilicone polymer, offering much lower surface energy and stronger chemical resistance than standard silicone liners.
They are specifically engineered for use with high-tack silicone adhesives or chemically aggressive formulations, where traditional silicone liners may fail due to sticking, residue, or migration.
Key differences from standard silicone liners:
Better release with silicone adhesives – avoids unwanted bonding or adhesive lift
Higher chemical resistance – ideal for challenging environments (e.g., medical, industrial electronics)
Lower surface energy – supports ultra-low release force, even with high-tack PSAs
Enhanced thermal stability – suitable for high-temp curing or converting
Fluorosilicone liners are often used in transdermal patches, EMI tapes, optical films, and die-cut components requiring precise release without surface contamination.
Fluorosilicone liners are available in a wide range of release forces, typically from <3g/25mm to >30g/25mm, depending on adhesive type and application. Custom release levels are also available.
Yes. We offer one-side or double-side release options, including asymmetric release force (e.g., easy-release side + tight-release side), based on your coating or converting needs.
These liners are specifically designed for silicone adhesives, and are also compatible with high-tack acrylic or hydrogel adhesives that require ultra-low release force to prevent liner distortion or adhesive lift.
Yes. We offer multiple PET base film thicknesses (e.g., 25μm / 50μm / 75μm) and can provide custom color, appearance, or anti-static layers upon request.
Our liners maintain stable performance under heat, pressure, and humidity, making them suitable for lamination, sterilization, and high-speed converting environments.
No. When correctly matched with your adhesive type, fluorosilicone liners ensure clean release with no adhesive residue or transfer. Testing with your adhesive is recommended.
Yes. We provide:
TDS (Technical Data Sheet)
MSDS / COA
Standard or custom sample rolls
Lead time for samples is usually 3–5 working days.
