HDPE SELF ADHESIVE BITUMEN WATERPROOF MEMBRANE

Product introduction

PRODUCT DESCRIPTION

HDPE self adhesive bitumen Waterproof Membrane is a high-performance, cold construction self-adhesive waterproofing membrane composed of specially made cross laminated high-density polyethylene (HDPE) strong film and high-quality polymer self-adhesive rubber bitumen through special processes. It has excellent size stability, thermal stability, UV resistance, and bidirectional tear resistance.

The strong cross film used in this product is a high-strength HDPE film formed by cross lamination and lamination process. The film made by this process has the same longitudinal and transverse elongation, and the membrane will not deform, which is more beautiful and has more reliable waterproof effect.

Adopting high-quality pressure-sensitive reaction self-adhesive adhesive layer, it can quickly combine with the concrete base, and its excellent self-healing performance and local self locking performance greatly reduce the probability of leakage. The polymer (chain segment) in the membrane adhesive forms an interpenetrating network structure with the cement hydrate (silicate network), ultimately forming a continuous mechanical bond that is permanently sealed on the cement cementitious material component.

The ordinary film is a unidirectional stretching film, and the self-adhesive membrane produced using this film will wrinkle when it encounters temperature changes after laying, and excessive deformation can easily cause the membrane to be torn.

This strong film is produced from multiple layers of specially formulated films through multiple processes such as crossover and lamination. It overcomes many shortcomings of ordinary films and has characteristics such as high tensile strength, sun resistance, and non foaming. Its technical indicators can meet the international requirements for type ii waterproof rolls and can be used as a surface material for waterproof membrane.

PRODUCT FEATURES

▪ The new pre laid wet bonding technology forms a permanent organic bond between the membrane and the structural concrete, without any potential water leakage, completely improving the reliability of the waterproof layer.

▪ Excellent impact resistance and puncture resistance, able to withstand construction loads and the impact of steel bars. during pre laying and anti bonding construction, no extra protection is required, and concrete pouring can be carried out directly.

▪ Adopting a special formula, the self-adhesive layer has strong self-healing ability and unique self-healing ability for minor construction damage.

▪ Chemical corrosion resistance, with good resistance to alkaline water from concrete. not affected by microorganisms, resistant to mold and corrosion.

▪ During wet paving construction, there is a low requirement for the construction surface and it is not affected by the dampness of the base layer. It has obvious advantages in rainy season construction and rush period engineering.
