Difference between rubber waterstop and P-type waterstop

Hello, what's the difference between rubber waterstop and P-type waterstop?

Rubber water stop is made of natural rubber and synthetic rubber as the main raw materials, with various additives and fillers, after plasticizing, mixing and pressing. There are many varieties and specifications, including bridge type, mountain type, P type, U type, Z type, B type, T type, H type, E type and Q type. According to the use situation, it can be divided into embedded rubber water stop and back-attached rubber water stop. The waterproof material has good elasticity, wear resistance, aging resistance and tear resistance, strong deformation adaptability and good waterproof performance, and the temperature range is -45℃-+60℃. When the temperature exceeds 70℃ and the rubber water stop is strongly oxidized or corroded by organic solvents such as oil, rubber water stop shall not be used. It is commonly used in the construction of basement exterior wall and post-pouring belt. ?

The water stop is made of polymer inorganic water-absorbing and swelling materials and rubber, and is a material for preventing the leakage of construction joints in various underground construction projects, water conservancy projects, traffic tunnel projects, cooling towers of power plants, municipal water supply and drainage projects, etc. Template bolt holes and construction joints of reinforced concrete outdoor walls are the main hidden parts of building leakage. Multi-purpose BW water stop is a new type of self-adhesive material composed of polymers, inorganic water-absorbing and swelling materials, rubber and additives. When it meets water, it absorbs moisture, expands in volume, and squeezes the gap between new and old concrete to form an impermeable plastic colloid. ? I hope I can help you. Thank you.
