- Blow Moulding: For containers and hollow components.
- Welding: PVDF can be effectively welded using various techniques.
Environmental Impact and Recycling:
- PVDF can be recycled, but specialised processes are required due to its chemical stability.
- Post-industrial waste can be reprocessed, but high levels of post-consumer recycling are less common.
Storage and Handling:
- Store PVDF in a cool, dry environment. It is stable under typical storage conditions.
- Ensure adequate ventilation when processing to prevent inhalation of fumes.
Safety Information:
- PVDF is inert and safe to handle in its polymer form.
- During processing, fumes can be generated and should not be inhaled. Ensure proper ventilation and use appropriate personal protective equipment.
