Description

1. Water resistance

Water resistance means that its performance is basically unchanged under the action of water and after being infiltrated by water, and it is impermeable under the action of pressure water. It is usually expressed by indicators such as water impermeability and water absorption.

2. Temperature stability

Temperature stability refers to the performance of non-flowing, non-foaming, non-sliding at high temperature, and non-brittle cracking at low temperature, that is, the ability to maintain the original performance under a certain temperature change. Commonly used indicators such as heat resistance and heat resistance.

3. Mechanical strength, elongation and fracture resistance

It refers to the performance of waterproofing membranes to withstand a certain load, stress or not to break under certain deformation conditions. Commonly used indicators such as tensile strength, tensile strength and elongation at break.

4. Flexibility

Flexibility refers to the performance of maintaining flexibility under low temperature conditions. It is very important to ensure easy construction and no embrittlement. Commonly used indicators such as flexibility and low-temperature bendability.

5. Atmospheric stability

Atmospheric stability refers to the ability to resist erosion under the long-term combined action of factors such as sunlight, heat, ozone and other chemical corrosive media. Commonly used indicators such as aging resistance and thermal aging retention rate.
