Resin Flows Easily for Vacuum Bagging
Divinymat has been engineered specifically for the resin infusion process and serves as both a sandwich core and a flow media.
Divinymat is a 3.8-pound per cubic foot DIAB Divinycell H foam. As a foam sandwich core, it provides the highest strength-for-density in its application range, which includes marine and land transportation, wind energy, civil engineering/infrastructure, and general industrial markets. It also delivers solid compressive and shear strength in both ambient and elevated temperatures.
Cross-scoring, as well as grooves and perforations, at the surface of the foam create controlled flow channels for resin during the infusion process. It offers the highest structural properties of any available flow media.
- Bonded to a light scrim cloth at its back, allowing it to conform to most simple curves and shapes
- Compatible with epoxy, polyester, and vinyl ester resins
- Features chemical resistance, low water absorption, and good thermal/acoustic insulation
- Store out of direct sunlight
Divinymat is sold by the sheet (32" x 48") and is 1⁄8" thick.
Showerpan liner makes a great vacuum bag.
Recently I used the mat to reinforce an installed shower bay so I could add handicap grab bars. I cut the mat into a single long strand (1 cell x 2 ft) and coiled it up. Saturated it with polyurethane glue and fed the coil into gap behind the new grab bar location. Whatever adhesive or resin you use, the coremat is a fantastic reinforcing tool. It is SCORED (cut into cubes) and that makes all the difference when creating rigid honeycomb structures.
