Neoprene's burn point is around 260 °C (500 °F). [21] In its native state, neoprene is a very pliable rubber-like material with insulating properties similar to rubber or other solid plastics. Neoprene foam is used in many applications and is produced in either closed-cell or open-cell form.
The elastomeric pad may made from any of several materials, including natural rubber, elastomers, teflon, or synthetic rubber (such as neoprene). Elastomeric bearing pads are the most economical solution used in construction of large span bridges and buildings. [1] [2]
Neoprene bearing pads (rubber like structure), a special type of bridge bearing, loses its energy through deformation. It simplifies the load transfer mechanism and hence, making analysis easier. See also
Rubber pad forming process, 1: bottom of the press. 2: lower die. 3: sheet metal. 4: rubber pad. 5: top of the press. Rubber pad forming (RPF) is a metalworking process where sheet metal is pressed between a die and a rubber block, made of polyurethane. Under pressure, the rubber and sheet metal are driven into the die and conform to its shape ...
The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber (neoprene) using metal oxides.
The neoprene pads used in sprung floors may be described as having open cells or closed cells. A cell is a void inside the neoprene, which may be a single cell or a network of small ones. A closed cell is like a balloon, where the air inside cannot escape and the pad is bouncy and returns most of the energy put in.
