Pre impregnated carbon fiber special blue film

Introduction to Carbon Fiber Special Blue Film (Carbon Fiber Prepreg Protective Film) for Prepreg Material

Core conclusion: Pre impregnated carbon fiber special blue film is a functional protective film customized for carbon fiber pre impregnated material (resin impregnated carbon fiber substrate), with the core value of "anti sticking isolation+anti fouling protection+auxiliary molding". Through low viscosity adaptation and resin compatibility characteristics, it avoids pre impregnated material adhesion, pollution or resin migration, ensures its storage, transportation and subsequent molding (hot pressing/molding) quality, and is a key supporting material for the entire process of carbon fiber pre impregnated material processing.

Basic definition and core characteristics

Pre impregnated carbon fiber special blue film is a blue functional film made from PE (polyethylene) or PP (polypropylene) as the substrate, modified formula and surface anti sticking treatment. It is designed specifically for carbon fiber pre impregnated materials (epoxy, phenolic, BMI and other resin systems).

• Core components: modified PE/PP substrate+low viscosity anti sticking coating (silicone or special inert coating)

• Core features: Low surface adhesion (180 ° peel force 0.05-0.3N/25mm), compatible with prepreg resin (non reactive, non migratory), temperature resistance range -20 ℃ to 120 ℃ (special models can reach 150 ℃), moderate light transmittance (easy to observe prepreg status), tear resistance, easy peeling without residue

• Core difference: Different from ordinary blue film, specialized blue film is optimized for the prepreg resin system to avoid resin adhesion or coating migration contaminating the prepreg; Different from general protective films, the low adhesive properties are more suitable for uncured resins, and the carbon fiber texture is not damaged during peeling

• Applicable objects: various uncured/semi cured carbon fiber prepreg rolls and sheets, such as epoxy based carbon fiber prepreg, phenolic based carbon fiber prepreg, BMI high-temperature resistant carbon fiber prepreg, etc
