Title:
FLUORORUBBER COMPOSITION AND SHAPED OBJECT
Document Type and Number:
WIPO Patent Application WO/2023/054716
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a new technique whereby a shaped object capable of exhibiting excellent stretchability at high temperatures can be formed using a fluororubber and single-layer carbon nanotubes (CNTs). The fluororubber composition according to the present invention comprises a fluororubber and carbon nanotubes. The carbon nanotubes include single-layer CNTs. This fluororubber composition, in a dynamic viscoelasticity test conducted under the measurement conditions of a frequency of 1 Hz and a temperature of 40°C, has a γG* as calculated with the following equation (I) of 20 or greater. Equation (I): γG*=G*
L/G*
H (wherein G*
L (kPa) is the complex modulus at a dynamic strain of 0.1% and G*
H (kPa) is the complex modulus at a dynamic strain of 630%).
