Abstract:
It is thus a principal object of the invention to provide an improved constrained layer composite damping material having a high loss factor throughout an extended temperature range of about -100 degrees F. to 160 degrees F. The composition of the present invention includes a composition of two different elastomers, a thermoplastic polymer, a plasticizer and a reinforcing filler. The first elastomer has a glass transitional point temperature f -50 degrees F., the second elastomer has a glass transitional point temperature of 60 degrees F. and the thermoplastic material has a glass transitional point temperature of 130 degrees F.
