Composite Molding Tape Solutions
The composite molding process requires materials that can withstand extreme temperatures, release cleanly without leaving adhesive residue, and protect costly tooling—especially for large, high-value components in aerospace and wind energy markets. In aerospace, composite molding is now essential, driven by trends such as weight reduction for greater fuel efficiency, advanced geometries that enhance aerodynamics and structural integrity, and sustainability initiatives pushing manufacturers toward PFAS-free materials. Choosing the right tape is critical to reducing defects, preventing resin overflow, and ensuring a flawless finish.
Our high-temperature, non-stick tapes not only safeguard tooling but also improve process efficiency by leaving no adhesive residue and minimizing post-production work. From PTFE (Teflon) molding tapes to PTFE coated fiberglass tapes to polyester (PET) flash masking tapes, Saint-Gobain® solutions help manufacturers achieve clean masking lines, fewer defects, and a longer tool life. Whether you’re producing wind turbine blades or lightweight aircraft composite parts, our tapes deliver the performance and reliability needed for demanding composite applications.
Popular Tape Types for Composite Molding
- PTFE molding tapes
- PTFE coated fiberglass tapes
- Polyester (PET) masking tapes
- Not only tapes, but also films such as PTFE, FEP, ETFE, & PMP are commonly used in composite molding applications. Tape Solutions also offers these films to round out our tape portfolio offered for composite molding masking and protection applications.
Are you looking for a PFAS-free* alternative?
Ask our team about our newest innovation, the Norgard® 2555 PFAS-free* Composite Molding Tape. This tape is specially engineered for demanding applications in aerospace, automotive, and industrial manufacturing.
Key benefits include:
- As a PFAS-free* material, it is a sustainable alternative to traditional PTFE-based tapes
- This is a high-performance tape with temperature resistance of up to 200°C (400°F) and clean removal after heat and/or vacuum exposure
- This tape is suitable for a variety of applications including vacuum bagging, resin transfer molding, and autoclave curing
As industries move toward PFAS-free alternatives, 2555 helps manufacturers meet environmental regulations without sacrificing quality or efficiency.
Norgard 2555 is a conformable, non-fluoropolymer composite molding tape that withstands the temperatures of composite molding yet still removes cleanly just like all of our other tapes. We are targeting a number of Boeing composite molding specifications for our non-PFAS and non-silicone tapes including BAC 5034, BAC 5157, BAC 5241, BAC 5317, BAC 5332, BAC 5412, BAC 5514, BAC 5548, BAC 5578, & BAC 5597. These are some of the most common specifications used by Boeing for their composite molding manufacturing processes.”
