From aeronautic, through transportation to consumer goods, many application areas are now unimaginable without fiber-reinforced plastic composites. WACKER silicone rubbers and fabrics for re-usable vacuum bags improve the composite resin infusion molding process. These silicone bags are placed quickly and securely over the mold before each part is produced. Repeated, time-consuming sealing with conventional vacuum film is no longer necessary.
Large number of reproductions: the bags (approx. 4x3 m) can be rolled up for transportation and used again and again. This bag has already beed used 250 times.
Benefits of Silicone Bag Technology:
- Faster production
- Better repeatability and quality
- Lower emissions of volatile components
- Less waste
- Less labor intensive
Benefits of ELASTOSIL®:
- Yet self-leveling
- Longer pot life and curing time
- Suitable for large surfaces
- Suitable for vertical surfaces
Silicones are also used for the production of wedges or bladders, used to apply pressure to the composite during the manufacturing process. Re-usability and release properties together with good chemical resistance are the key advantages here.
