High temperature resistance 370℃ FFKM

370℃ Class FFKM 

Fluoro-Power FFSG (Fluoro-Power FFSG / FP-FFSG) is a rubber material for O-rings with heat resistance, which is the highest in the world at 370 ℃ class . Various FFKM (perflo) materials, which are considered to be synonymous with high-performance fluororubber , are the flagship of the Fluoro-Power® series due to their excellent chemical resistance as well as heat resistance. It is an advanced polymer compoundthat bears the burden of. Is their raw materials " perfluoroelastomer ( FFKM) to" Nippon Zeon tip material in cooperation with "SGCNT (see Super Growth single-walled Carbon Nanotube = SWNTs / or below supergrowth Method)" It is this Fluoropower FF SG that has succeeded in blending. The encounter of the art, which has played a vertex to as a choice in a high temperature range fluoroalkyl power FFS and fluoroalkyl power FFSW grade refractory grade surpassing the birth, we Ainari and the limit value of the rubber material is increased updated rice field.

About "SGCNT" from Japan

CNT is a kind of allotrope made of carbon, "Carbon Nanotube". Nanomaterials (materials with a particle size of 100 nm or less. 1 nm = 1 nanometer is 10-9 meters, that is, one billionth of a meter), which is considered to be the next-generation carbon material . It is classified into carbon nanotubes (Single-Walled Carbon Nanotube) and MWCNTs (multi-Walled Carbon Nanotubes). The "CNT" of "SGCNT" used in Fluoropower FFSG is SWCNT. SWCNTs have the characteristics of high thermal and electrical conductivity and high strength, and they play an important role in supporting the outstanding heat resistance of Fluoropower FFSG. "SG" in "SGCNT" is a CVD method developed by AIST (National Institute of Advanced Industrial Science and Technology) based on the results of the NEDO (New Energy and Industrial Technology Development Organization) project. It represents one of the (methods of thermally decomposing nanoparticles of catalyst metal and hydrocarbons to obtain CNTs), "a Super Growth method". Although CNT (SWCNT) has rare properties, it is also a material that is difficult to exceed the range of applications for academic research because it requires a large amount of cost for synthesis. The super growth method is what brought the cost closer to a practical level. This epoch-making synthesis technology dramatically extends the life of the catalyst in the synthetic atmosphere by adding a very small amount of water, which makes it possible to produce a large amount of CNT (SWCNT) with 3,000 times the time efficiency of the conventional one. I did. However, SGCNT is still expensive to use as a compounding material for rubber products and is a rubber compound.In the manufacturing process of, there are still many problems such as the need for special technology to uniformly disperse in polymers such as perfluoroelastomer (FFKM). However, I strongly hope that SGCNT and Fluoropower FFSG, spun by Japanese science and technology, will be able to illuminate a wide range of industries and research fields around the world beyond Japan and contribute widely. We are doing it.

Chemical structure

4 Ethylene fluoride / perfluoroalkyl ether copolymer. Since all of the main chains are fluorine bonds (CF) and there are no hydrocarbon bonds (CH), they have extremely excellent chemical resistance and heat resistance. Since the structure is almost fluoride as a whole, it is difficult to crosslink , so CSM is added as an auxiliary leg.

Fluoropower FFSG (heat resistant FFKM / special grade) characteristic value and physical property value

Many of the high-performance rubber materials listed by manufacturers such as Fluoro- Power® and Kalrez®can be used interchangeably, but they are given special performance for specific purposes. Some of them are included. When handling it as an equivalent product, carefully check the conditions of use .

 Fluoropower FFSG and high temperature x long time (300 ° C x 670 hours) heat resistant aging test 

We conducted a heat-resistant aging test under special conditions (300 ° C x maximum 670 hours) for the top two grades of heat-resistant FFKM (Fluoropower FFSG and Fluoropower FFSW ) . The data is as follows.

Physical characteristics of Fluoropower FFSG

 Operating temperature limit

The recommended value is 0 to 370 ° C. However, continuous use in the maximum temperature range tends to cause damage due to thermosetting, shortening the service life. Also, in the lowest temperature range , the rubber elasticity deteriorates, so the sealing performance deteriorates . be careful.

 Pressure characteristics

The recommended maximum pressure is 10MPa. However, the values will vary depending on the conditions. In addition, the pressure resistance is a combination of the backup ring can be improved by.

 chemical resistance

Extremely excellent. It is resistant to all chemicals and has outstanding performance among various rubber materials. Please refer to the table below for a list of durability against more liquids and gases in terms of chemical resistance (compatibility between contact fluid and material) of O-rings .

◎: Can be used 〇: There is some influence △: Not recommended X: Cannot be used
