Abstract

PURPOSE: The title material having improved vibration damping and sound insulating properties free from odor, pollution, and sagging, etc., comprising a rubber melt, obtained by thermal decomposition of rubber, and a base polymer.
CONSTITUTION: (A) A base polymer selected from asphalt, rubber, polyurethane, etc. is incorporated with (B) 5W90 wt.% based on the total weight of the composition of a rubber melt, obtained by thermal decomposition of rubber at 220W430°C, preferably 290W400°C, and, if necessary, vulcanizing agents, vuclanization assistants, etc. The material is preferably vulcanized for use at high temperatures.
USE: Noise or vibration can be reduced by surrounding the noise or vibration source with a sheet consisting of the material or by bringing the sheet into close contact with the source. Alternatively, a place to be protected against noise or vibration is inclosed by the sheet.
