Neoprene polychloroprene is an extremely versatile synthetic rubber with more than 75 years of
proven performance in a broad industry spectrum. It was originally developed as an oil-resistant substitute for natural rubber.
Neoprene is noted for a unique combination of properties, which has led to its use in thousands of applications in diverse
environments.
- Resists degradation from sun, ozone and weather
- Performs well in contact with
oils and many chemicals
- Remains useful over a wide temperature range
- Displays outstanding physical toughness
- Resists burning inherently better
than exclusively hydrocarbon rubbers
- Outstanding resistance to damage caused by flexing
and twisting
The basic chemical composition of Neoprene synthetic rubber is polychloroprene.
The polymer structure can be modified by copolymerizing chloroprene with sulfur and/or 2,3 dichloro 1,3-butadiene to yield
a family of materials with a broad range of chemical and physical properties. By proper selection and formulation of these
polymers, the compounder can achieve optimum performance for a given end-use. Neoprene is available as a solid and as a liquid
dispersion.
Neoprene Bearing Pads provide a uniform transfer of load to beam to substructure. They
permit beam rotation at the bearing point due to deflection or misalignment. They absorb vibration between movable and stationary
structural members. they also provide for movement caused by normal expansion and contraction. Neoprene Bearing Pads are used
extensively in bridge structures and prestressed and pre-cast concrete buildings. Also used in industrial machinery and heavy
equipment.
