Industrial rubber sheets are typically made of Synthetic Rubber, such as Neoprene (CR), Nitrile (NBR), or EPDM. They may also be made of natural rubber, which is derived from the rubber tree. Industrial rubber sheets are used for a variety of applications, including sealing, gasketing, and weatherstripping. They are also used as flooring in commercial and industrial settings, as well as in the automotive and aerospace industries.
