Composite Release Liners

Fox River Associates offers a full line of release liners for composite applications including prepreg manufacturing operations, composite panel production and resin film processing.

When a composite material is produced, the composite release liner prevents the material from sticking together while the material is stored. Composite materials are often stored in freezing temperatures between various processes.  Composite release liners from Fox River Associates are made to withstand very low temperatures and moisture.

Full line of Paper and Film Release Liners

Fox River Associates offers a full line of paper release liners, embossed film release liners, and thin gauge, flat film release liners with built-in improved release properties.

Sourcing a composite release liner with excellent dimensional stability can make a difference in the quality of the prepreg material 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.

Our line of film release liners includes silicone coated liners to work with high tack resin systems and embossed films that provide your needed release characteristics. Our goal is to deliver the composite release liner that helps your product appear and perform its best when it arrives at your customer.

Improved release properties can be included in the formulation of some flat film release liners provided by Fox River Associates. These products do not require a separate release coating that may be susceptible to transfer to your material. These films are often laminated to the resin at the back end of the filming process. These flat film release liners are removed during the prepreg process and help eliminate resin pick off issues. This helps ensure that all the resin transfers from the release paper to the fiber material helping prepregers achieve the tighter resin/fiber tolerances required for many aerospace applications.

Using the optimum liner combination will help you to you deliver tighter tolerance material no matter the end use (aerospace, recreational, industrial, etc.). Paper and film liners from Fox River Associates help ensure that your prepreg process helps deliver the highest quality product to your customers.
