Product Overview
Description
1. Product introduction
(TPO)-TBP pre-laid waterproof membrane is composed of thermoplastic polyolefin sheet (TPO), polymer hot melt adhesive or butyl rubber, and surface particles and coating as the anti-adhesive layer, pre-laid anti-adhesive to achieve integration with the concrete structure The formation of effective interpenetrating bonding and huge intermolecular force between the two, so that the TPO waterproof membrane and the main body of the structure have been sealed, completely eliminate the channel of water.
2. Product specifications
Thickness: 1.2mm 1.5mm 1.8mm
Width: 1-2M
Length: ≥20M

3. Product characteristics
★Good flexibility: soft hand feeling, good conformability between the coil and the surface and corners of the base layer.
★Long service life: No plasticizer is added to the sheet material to maintain long-term weather resistance without aging.
★Good resistance to high and low temperature: It can be used for a long time under the environment of -40℃—120℃ without change.
★Weldability: Hot-air welder can be used at the lap joint, and the temperature is 400℃-550℃ for direct welding, which has stronger operability.
★Good self-adhesiveness: The polymer self-adhesive film has good initial adhesion, high cohesion, and strong adhesion after reacting with concrete.
4. Product application range
(TPO)-TBP pre-paved waterproofing membrane can be applied to waterproof engineering projects such as industrial and civil buildings, rail transit, tunnels, and underground comprehensive pipe corridors.
