High-Temperature Resistant Water Barrier Strip Durable and Flexible for Industrial and Construction Waterproofing Solutions

For width, it depends on the application. In construction, widths from 10 - 50 mm are common for general use, while in automotive applications, 5 - 20 mm strips are often used. For thickness, in construction, 2 - 8 mm is typical, and in automotive, 1 - 3 mm strips are more common. Measure the gap or joint where the strip will be installed. A wider and thicker strip is usually needed for larger gaps or more demanding waterproofing requirements. Make sure to consider the tolerance; width tolerance should be within ±0.5 mm and thickness tolerance within ±0.2 mm for proper fit and performance.

In construction, water barrier strips should resist a water column height of at least 500 mm for 24 hours without leakage. In automotive applications, they need to withstand the water pressure during car washing and normal wet - weather driving.

Yes, they are designed to be resistant to common chemicals. They can withstand exposure to acids (pH 4 - 6), alkalis (pH 8 - 10), and common solvents such as ethanol, isopropyl alcohol, and diesel fuel. After 24 - hour exposure at room temperature, there should be no significant change in physical properties like hardness, tensile strength, and elongation at break.
