The NuPLUG 2120 R* Foam is a flexible product used as both a radiation barrier and as a fire break to caulk electrical and mechanical penetration assemblies, as well as sheaths cast in both concrete slabs and walls.
* Also named "935.P"
Product Data
- Bi-component silicone foam
- Shielding factor for gamma radiation, X-rays and neutrons equivalent to that of concrete
- A flexible product that enables insertion of extra penetration modules in penetration assemblies that have already been caulked
- Acts as a fire break for up to two hours (EI 120) (Tested according to the 2004 French decree and the EN 1366–3 standard)
- Product used for caulking penetration assemblies with a 60% saturation level
- Product can be imbued with both sealant and decontaminable properties by coating it in a complementary MECATISS product such as NuCOAT 7110 I Fabric (SILCO) or NuCOAT 3110 I Elastomer (TSR 750)
Operational Information
- Minimum usage thickness: 250 mm
- To be used on clean, dry and degreased surfaces
- Three possibilities for implementation:
o Pneumatic pump (for large volumes)
o Manual or pneumatic caulking gun (for filling small volumes)
o Manually, through the use of gravity (for easily accessed volumes)
- Setting time: < 15 min
- Complete cross-linking: Twenty-four hours
- End product density (polymerised): 2.4 to 2.6
Other Technical Information (Packaging, Storage)
