The reader is cautioned that the “General Properties” described are just that, properties which have been found to be generally
applicable in the experience of persons familiar with rubber chemistry. However, the reader should always follow the
manufacturer’s recommendation as to the use of any particular rubber composition, especially with respect to the resistance of the
rubber composition to the materials it is intended to carry or protect against. Failure to do so may also result in failure of the
product to fulfill its intended purpose and may result in possible damage to property and/or serious bodily injury.
