- Prepreg fabric and tape are generally shipped via refrigerated truck in sealed polyethylene bags. Disposal of Scrap Disposal of this material should be in accordance with state and federal regulations.
Storage & Handling
- Product Handling and Safety
Hexcel recommends that customers observe established precautions for handling resins and fine fibrous materials. Operators working with this product should wear clean, impervious gloves to reduce the possibility of skin contact and to prevent contamination of the material.
- Storage
HexPly® F515 prepreg should be sealed in a polyethylene bag and refrigerated, preferably below 32°F (0°C). Following removal from refrigerated source, allow the prepreg to reach room temperature before opening the polyethylene bag to avoid moisture condensation. Shelf life: 6 months at 0°F (–18°C), 3 months at 40°F (4°C) (maximum, from date of manufacture).
