An important component used in the moulding of composite objects is the material used to line the mould tool. Mould liners, also referred to as mould releases or release liners, protect the mould from the resins used and ideally enable a quick and clean release of the moulded product from the mould/release liner.

For less complex shapes, PTFE coated fabric serves as an effective mould release. Where mould tools are more complex, adhesive fabrics or tapes are used to prevent shifting.

In both fabric and tape mould release applications, the base fabric is generally PTFE coated fiberglass. For tapes, pressure sensitive silicone adhesive allows easy application, a sure grip, and quick and clean release. For best results, the grade of fabric and thickness/grade of PTFE should be based on the demands of the job.

Our standard mould release material is PTFE Coated Fiberglass Tape 
(3 mil, 5 mil, and 6 mil) which is a tape with pressure-sensitive adhesive that will conform and remain in place easier than a coated fabric. Depending on the application, different grades, offer varying degrees of finish and durability for multiple uses.

Once the resin and composite material has been filled into the mould, the curing process follows. When the product has cured, the PTFE fabric/tape allows for clean release from the tooling and the composite part is now complete.

PTFE Coated Fiberglass Fabric/Tape is best suited for this application due to its high heat and abrasion resistance which is effective during the curing stage. Exceptional release characteristics allow the composite product to release cleanly from the mould.
