Abstract (en)
[origin: WO9404822A1] Noise absorbing composite for the suspension system of compressors, motors and similar apparatus, which can be used in a suspension system of the type defined by metallic helical springs (3A, 3B), which interconnect a fixed case (2) of a hermetic compressor with its motor-pump assembly (1), the latter being provided with a high frequency vibratory movement, said noise absorbing composite (10) being defined by a portion of viscoelastic material, disposed in close and permanent contact with a substantial portion of the surface of said springs (3A, 3B), said viscoelastic material (10) comprising: a main elastomeric portion, defined by 100 parts of a compound, which is selected from the group consisting of: polysiloxanes, tetracyclosiloxanes, pentacyclosiloxanes or mixtures thereof; a portion of vulcanization, defined from 0.2 to 6.0 phr of a compound selected from the group consisting of: di-cumile peroxide; 2.5-bis (ter-butyl) peroxide; 2.5 dimethylhexane, or mixtures thereof.
