CompoFlex™ SB 250 – 3-in-1 Peel Ply, Release & Breather 60"x61m" Roll

CompoFlex™ SB 250 – 3-in-1 Peel Ply, Release & Breather

CompoFlex™ SB 250 is a high-performance, microporous composite consumable designed to simplify your vacuum bagging process. Engineered for efficiency, it combines the functions of peel ply, release film, and breather into a single easy-to-use layer—reducing material use, saving time, and improving consistency.

Built with a breathable polypropylene nonwoven structure, SB 250 allows controlled air and resin movement while maintaining excellent release properties. It peels cleanly with minimal force, leaving behind a uniform, bond-ready surface ideal for secondary bonding—without the need for additional surface prep.

Compared to traditional peel ply systems, CompoFlex™ requires significantly less peel force and helps minimize airborne resin dust, creating a cleaner and safer working environment.

Key Benefits

• 3-in-1 solution: replaces peel ply, release film, and breather

• Produces a consistent surface ready for secondary bonding

• Easy peel with reduced force vs. traditional peel ply

• Minimizes resin dust during removal

• Reduces consumables, labor, and cleanup time

• Improves process efficiency and repeatability

Ideal Applications

• Vacuum bagging of prepreg composites

• Wet lay-up with vacuum compression (light to moderate resin content)

• Aerospace, marine, and industrial composite manufacturing

Technical Highlights

• Thickness: ~1.3 mm

• Resin Capacity: ~0.81 L/m²

• Composition: 100% Polypropylene

• Max Working Temperature: 145°C (293°F)

• Designed for vacuum bagging applications

Important Note
CompoFlex™ SB 250 is designed to simplify vacuum bagging setups. For resin infusion processes, a dedicated flow media is still recommended.
