Traditionally, automotive body mounts have consisted of a steel casing with either a natural rubber, a blend of natural rubber to increase certain properties, or Butyl. In the past several years synthetic rubber technology has expanded and thermoplastic elastomers (TPE) have been introduced. TPEs can retain the same properties of a natural rubber and reduce the cost of producing a body mount. This study comprises a comparison of thermoplastic elastomers to materials traditionally used in automotive body mount applications.
