Rubber Sealing Strip

This type of rubber expands and deforms by 2-3 times upon contact with water, filling all irregular surfaces, cavities, and gaps in the seam.

Generate tremendous contact pressure to prevent leakage. When joints or construction joints shift, causing gaps to exceed the material's elastic range.

At this point, the ordinary rubber waterproofing material loses its waterproofing effect. However, this material can also stop water by absorbing water and expanding.

Expanded rubber as a leak-proof sealing material, not only saves quantity, but also prevents excessive compression from causing deformation in general elastic materials.

Characteristics of sexual fatigue enhance the reliability of waterproof performance.
