Ultra Low Extractable Release Liners

AR’s ultra-low extractable silicone release liners are manufactured using proprietary, platinum-catalyzed coating chemistries that achieve extractable levels below 30 ng/cm²—significantly lower than conventional silicone-coated liners. This extremely low extractable profile prevents loose silicone molecules from transferring onto adjacent adhesive or film surfaces, ensuring product purity and consistent downstream adhesion.

These liners are commonly used in applications where the slightest contamination can cause device failure, such as in hard disk drive components, optical sensors, and cleanroom-assembled electronic modules. The controlled silicone layer maintains uniform release forces and stable surface energy across the entire web, ensuring reliable peeling, lamination, and component separation without residue or haze formation.

ARclean® Ultra-Low Extractable Release Liners are available on a range of substrates, including clear and white PET films, as well as custom-engineered base films for thermal, optical, or dimensional stability. Our manufacturing processes ensure coating uniformity, low particulate levels, and tight quality control standards for consistent batch-to-batch performance.

Different industries have unique cleanliness and performance demands. Our engineering and R&D teams collaborate directly with customers to define the optimal liner for their application, whether the goal is reduced silicone transfer, improved adhesion stability, or enhanced environmental resistance.

We offer test and validation services to measure extractable silicone content, adhesion performance, and release force consistency under simulated process conditions. When required, AR can modify coating thickness, substrate type, or curing profile to achieve specific peel performance or extractable targets. Our global technical support teams provide localized assistance through process qualification, operator training, and performance audits to ensure consistent, contamination-free manufacturing.

Select a liner grade based on adhesive chemistry, substrate type, and process cleanliness requirements. Store rolls in a clean, temperature-controlled environment around 70°F with low humidity to maintain coating stability. Handle liners using gloves or cleanroom procedures to avoid introducing particulates. During qualification, measure release force and check for silicone migration using standardized extractables testing (e.g., GC-MS or TOF-SIMS methods). Our technical specialists are available to support pilot trials, cleanliness audits, and process optimization for consistent performance.
