Mapeband TPE - TPE tape for flexible sealing and waterproofing expansion joints and over cracks subject to movement

Mapeband TPE consists of either 17 cm or 32.5 cm wide tape, called respectively Mapeband TPE 170 and Mapeband TPE 325, 1.2 mm thick, sidelong reinforced with polyester non-woven fabric.

Mapeband TPE must be applied by bonding with Adesilex PG4 two-component, low viscosity, thixotropic epoxy adhesive.

TPE, short for “Elastomeric Thermoplastic Polyolefine”, is the name given to a special group of polyolefines which combine the best properties of thermoplastic polymers and synthetic elastomer technology.

Mapeband TPE may be hot-welded with a Leister electronic hot air blower.

Mapeband TPE may be also joined by using the “cold-weld” technique by applying a contact adhesive, such as Adesilex LP solvented, poly-chloroprene adhesive, to both surfaces. This technique makes it easy to form linear joints or to create special pieces with the tape, to guarantee the waterproof integrity of the entire system.

The tape remains permanently flexible and deformable even at low temperatures and, furthermore, it is resistant to ageing even if exposed to atmospheric agents.

The composition of Mapeband TPE gives it excellent resistance to alkalis, bitumen, diluted lye, slightly acidic solutions and salt solutions.
