Neoprene Performs Around the Globe

Introduced by DuPont in 1931, Neoprene polychloroprene is the most tested, tried and proven of all synthetic rubbers. It has a long history of outstanding performance in construction projects around the world. Thanks to continual development and refinement, it is still the material of choice for many structural engineering projects.

Highway and Window Seals

Neoprene can be formulated for easy and quick extrusion of complex profiles for use in a wide variety of sealing applications. Crystallization resistant W-Types are usually used for outstanding low temperature properties and excellent compression set resistance. Highway and bridge seals have been manufactured with Neoprene for over 50 years. The products have good resistance to oil and ozone, providing protection from aging. Window seals can be produced for maintenance free applications in the most challenging designs and environments. This case study demonstrates how seals helped provide a solution for an earthquake and typhoon prone building with curved and oddly shaped windows.

Bridge Bearing Pads/Cable Seals/Boots

Neoprene has been used for many years as the elastomeric component of bridge bearing pads. It can also be used to seal cables and other architectural components. Neoprene's high tensile strength and low compression set, and excellent oil and ozone resistance make it ideal for these applications, as shown here. Crystallization resistant W-Types are usually used for outstanding low temperature properties and excellent compression set resistance.

Waterproof Membranes

A membrane made with Neoprene can provide watertight protection in a multitude of locations. It has a proven history of success, as shown in this case study of an indoor waterproofing system. T-Types are usually used for ease of extrusion.
