This specification covers a synthetic rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. These products have been typically used for parts, such as sleeves, fairings, grommets, and window channels, where resistance to low temperature is of prime importance, but usage is not limited to such applications. Each application should be considered individually. While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
