Mercer Rubber Company Product Overview
The Mercer Rubber Company was started in 1865 as a small factory on Mercer Street in Hamilton Square, New Jersey. The company specialized in molded rubber mechanical products, rubber sheeting and conveyor belting, and began building rubber expansion joints in the early 1930s. Mercer was completely owned by one family from its inception through 1982, when it became a sister to Mason Industries, one of the world’s largest producers of molded rubber expansion joints. Since that time, it has been managed by professional engineers, and we believe our engineering staff is proportionately larger than any other similar company in the United States.
Hand-built flexible connectors for piping and duct work solve problems that cannot be handled by other materials. Rubber is more compliant and resilient than metal, fiberglass or plastic. The technology behind building shapes for industrial applications has grown as well. The United States chemical and industrial complex is in the forefront of synthetic rubber for chemical resistance and temperature extremes. Modern reinforcement fabrics and tire cord have completely replaced early designs using cotton and rayon. The end result has been a lighter, more flexible, higher pressure and temperature resistant product.
In this brief presentation we can only tell you where the products are used and some of the things we do. Later in this section, we provide the details and data in separate bulletins for each of the products mentioned here. However, even then, you would have to let us know about your application, so if need be, we could design and build to your exact requirements.
I am sure that if you need a rubber expansion joint, duct connector or industrial hose, we can help. Please let us hear from you.
