Abstract
Novel room-temperature-vulcanized silicone rubber/calcium sulfate whisker composites have been prepared. Properties such as viscosity, hardness, tensile strength, elongation at break, and thermal stability were researched and compared. A combination of scanning electronic microscopy studies was used to characterize the structure and reinforcing mechanism of calcium sulfate whisker. Results showed that the addition of 10% calcium sulfate whisker-Y into room-temperature-vulcanized composites improved the tensile strength from 4.2 to 5.0 MPa and elongation at break from 210 to 590%. In addition, some improvement in thermal stability was obtained between 350 and 700°C for room-temperature-vulcanized systems.
