GUARDIAN Overwrap PVC Tape is an essential component of the GUARDIAN Petrolatum System, designed to provide enhanced mechanical protection and durability. Constructed from a stable, plasticized PVC carrier and coated with an antifungal, pressure-sensitive natural rubber adhesive, the tape is highly resistant to acids, alkalis, and bacterial attack. It improves the system’s dielectric strength and prevents the leaching of compounds into the backfill media when used with GUARDIAN Petrolatum Tapes.
