Issue 30/2015 - Winylidene flurane low-temperature resistant fluoroelastomer engineering technology awarded

The engineering technology development project of vinylidene flurane low-temperature resistant fluororubber completed by Zhonghao Chenguang Chemical Research Institute Co.
, Ltd.
won the first prize of Zigong Science and Technology Progress Award
.
The low-temperature resistant fluoroelastomer Tg developed by the project is as low as -32 °C, which can be used in a long-term -40 °C environment, breaking through the foreign technical blockade
of such products.

The key to the synthesis of low-temperature fluoroelastomers of vinylidene flurane lies in the introduction of specially modified monomers and the control technology
of the synthesis process.
Zhonghao Chenguang Institute successfully synthesized modified monomers through its own technology, and then developed the engineering technology of low-temperature fluoroelastomer for metafluoride and realized the production of pilot scale
.

The successful development of vinylidene flurane low-temperature resistant fluororubber has changed the phenomenon that domestic fluororubber has only two major categories of ordinary binary and ternary products for a long time, and the product structure is single, which provides technical support
for the diversified development of domestic fluororubber.
At the same time, the product also meets the requirements
of some low-temperature and fuel-resistant seals in domestic automobiles, aerospace and other fields.
At present, the engineering technology development project of vinylidene flurane low-temperature resistant fluororubber has applied for 2 national invention patents and 1 PCT patent
.
