Composite Release Liners from Fox River Associates

Fox River Associates has been supplying a full line of release liners for the advanced composite industry for more than 25 years. Our first-hand experience and knowledge of composite applications help us work together with you to identify the best release liner options for your applications.

Composite Release Liners

Whether you are producing fabric or unidirectional prepreg, manufacturing composite panels, producing resin films or another technical composite application utilizing a paper or film release liner, Fox River Associates is prepared to work with you. Due to the extreme conditions release liners are exposed to during processing and storage, release liners for composite applications must be engineered with specific performance characteristics. Layflat and dimensional stability are only two of the important characteristics of a quality prepreg release liner. Fox River Associates understands the unique characteristics of these demanding applications and is ready to serve your release liner needs.

Critical Factor - Dimensional Stability

Sourcing a composite release liner with excellent dimensional stability can make a difference in the quality of the prepreg material in your processes and when it arrives at your customer. Fox River Associates understands this and supplies paper-based liners with this important feature in mind. A paper release liner that has improved layflat properties and does not “expand” or “shrink” with changing environmental conditions will help ensure that your prepreg arrives at the customer in the best condition possible.

Fox River Associates – Experienced in Composite Release Liners!

Release liners from Fox River Associates are produced under tightly controlled process conditions. The silicone coating systems are thermally-cured. Sophisticated remoisturization equipment is utilized to replace much of the internal release liner moisture that is lost during the silicone curing process. Fox River Associates has the ability to supply siliconized paper release liners that have been targeted to a specific moisture range for optimum performance in your prepreg operation. The final result is a composite release liner that helps your product appear and perform its best when it arrives at your customer.

Protection from Environment = Improved Performance

Maintaining the proper moisture range in the advanced composite, paper based release liner is important to the performance of the product and of the final composites. Liner moisture levels can change before, during and after the prepreg production process, the layflat and dimensional stability properties of the liner can be negatively affected. These changes can lead to a final prepreg material that does not lay flat or can result in gaps appearing the prepreg after production.

Fox River Associates recommends keeping paper release liners protected in the original, moisture protective packaging until ready to use. This can help minimize the amount of moisture change in the finished composite release liner in your inventory. If the entire roll is not consumed in a single run, storing the unused siliconized paper release liner in a controlled environment (humidity and temperature) will help preserve the stability of the liner.
