INSULATION - ELECTRICAL PLASTIC SEALER
NEPSEAL 30 is a non-hardening, flame resistant sealant
specifically fomulated for use as a fire-stop material. For example, NEPSEAL 30 will prevent a shipboard fire from propagating
through a stuffing gland which contains electrical cables. On flame contact, the NEPSEAL 30 expands to approximately
twice its volume. In lab tests, cable exposed to direct flame melted immediately but the portion of the cable
protected by NEPSEAL 30 remained intact after four hours of continuous flame contact.
NEPSEAL 30 provides electrical insulating properties and excellent compatibility
with the electrical cable jacketing materials. This sealant contains no asbestos fibers.
NEPSEAL 30 meets the requirements of military specification MIL-I-3064B.
