Vacuum Bagging Films Take the Heat in Vacuum Infusion
Vacuum bagging processes require layers of vacuum bagging and process materials that are applied in a specific vacuum lay-up structure. It is important to use quality materials in the vacuum lay-up to get the best results in the end composite part. In all vacuum bagging processes, bagging film products are among the materials that are critical to the success of manufacturing parts.
The vacuum bagging film is typically placed over a series of prepreg, peel ply, release film, and breather fabric, just prior to the application of the vacuum process for part consolidation. Vacuum bagging films offer strength, ease of use, and excellent control and reliability in the manufacturing process.
Aerovac is a leading supplier of vacuum bagging film and other process materials that manufacturers need for vacuum bagging processing in a variety of applications and industry applications. Aerovac’s comprehensive range of products are focused on unique customer needs, with product features such as humidity resistance and tailored formatting to reducing labor costs.
Vacuum bagging films from Aerovac meet high-temperature requirements
There is a common requirement for vacuum bagging film to support elevated temperatures in the vacuum process. Aerovac offers a range of vacuum bagging films that support temperatures ranging from 248 degrees Fahrenheit (160 degrees Celsius) up to 800 degrees Fahrenheit (426 degrees Celsius).
The heat stabilized vacuum bagging film, Stretch-Vac (SV) 6000, for example, is ideally suited to aerospace applications. It has a high elongation and is suitable for high-temperature autoclave curing up to 419 degrees Fahrenheit (215 degrees Celsius). It is compatible with epoxies and BMIs and is recommended for bagging applications where a higher softness is required. Doubling that heat capacity, the VAC-PAK UHT 750 3 model of vacuum bagging film from Aerovac is an amber polymide film developed for use with high-temperature thermoplastic matrix materials up to 800 degrees Fahrenheit (426 degrees Celsius).
