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
NEPSEAL 30 is available in gallon cans (10 lbs. net)
NEPSEAL 30 contains a small amount of chopped glass to enhance the high temperature properties. It is, therefore, recommended that gloves be worn when working with this product to avoid skin irritation.
