Main performance   1
high temperature resistance fluororubber (FPM) has excellent high temperature resistance
It can work for a long time at 200-250 ℃ and for a short time at 300 ℃
The tensile strength and hardness of fluororubber decreased significantly with the increase of temperature
The change characteristics of tensile strength and hardness are that the tensile strength and hardness decrease rapidly with the increase of temperature below 150 ℃; Between 150-260 degrees, the downward trend is slow with the increase of temperature 2
corrosion resistance fluororubber (FPM) has excellent corrosion resistance
It has excellent stability to organic liquids, different fuel oils and lubricating oils, and good corrosion resistance to most organic acids, hydrocarbons, benzene and toluene 3
compression set performance fluororubber (FKM) is used for sealing at high temperature, and compression set performance is its key
Viton fluororubber is widely used because of the improvement of its compression deformation
In the 1960s and 1970s, DuPont company of the United States devoted itself to improving the resistance of fluororubber to compression deformation and achieved remarkable results 4
low temperature resistance fluororubber (FKM) can keep the limit temperature of elasticity at -15 ~ -20 ℃
With the decrease of temperature, its tensile strength increases and becomes strong and tough at low temperature
When the thickness is 2mm, the brittleness temperature is -30 ℃; When the thickness is 1
87mm, the temperature is -45 ℃; When the thickness is 0
63mm, the temperature is -53 ℃; When the thickness is 0
25, the temperature is -69 ℃
Generally, the service temperature of fluororubber can be slightly lower than the brittleness temperature 5
weather aging resistance and ozone resistance the performance of vitona after 10 years of natural storage is still satisfactory
In the air with ozone concentration of 0
01%, there was no obvious cracking after 45 days Our common materials: dozens of rubber materials, such as nitrile rubber (NBR), Viton, EPDM, VMQ, Cr, SBR, HNBR, etc
we can also provide products with shore hardness of 50 ~ 90
