brief introduction

In addition to excellent chemical resistance and heat resistance, the product has homogeneity, and the surface has no problems such as penetration, cracking and pinholes. These features can improve the sealing performance, prolong the operation cycle and effectively reduce the maintenance cost. Kalrez® The long-term life of the product will minimize unexpected downtime, improve equipment utilization and optimize production capacity.

The long-term efficacy of perfluoroether rubber sealing parts can improve production efficiency and reduce maintenance costs

These total costs are much higher than the initial purchase price. Selecting and installing kalrez & reg; High performance sealing products can prolong the mean time to repair (mtbr) and reduce irregular shutdown and maintenance costs.

For some special industries, the loss caused by abnormal shutdown is much greater than the cost of parts and labor. Perfluoroether rubber products can effectively help users improve the stability of the process, prolong the working time of the equipment and obtain the maximum benefits for customers.

Perfluoroether rubber has excellent high temperature resistance

In terms of heat resistance (based on the compression deformation test results of JIS k6301, etc.), perfluoroether rubber can also maintain the elastic characteristics of rubber at a high temperature of 300 ° C。

In jisk6301 compression set test, when the rubber material loses elasticity when heated, the deformation value will increase, which means that the sealing performance is decreasing. At 240 ° C, the deformation rate of fluororubber and other products increases sharply with time, while the compression set of perfluoroether rubber products remains below 50%. This proves that kalrez & reg; The product can also maintain good elasticity at high temperature.

◆Intuitive high temperature resistance experiment

◆Test of relationship between compression set and temperature (JIS k6301)

The measurement of compression permanent deformation is to use the measuring tool to compress the rubber test piece according to the provisions of jisk6301, take out the test piece immediately after placing it in a certain high-temperature environment for a certain time, and measure the deformation according to the right measuring formula。

Rubber changes due to heat. When the elasticity is lost, the deformation value will increase. The deformation value of fluorinated rubber will begin to increase sharply at about 200 degrees. Even at 300 degrees, the deformation rate of kalrez4079 does not exceed 20%. In addition, in the long-time compression deformation test at 200 ℃, the deformation rate of kalrez4079 remains below 50% for a long time.

Excellent chemical properties of perfluoroether rubber

In terms of chemical resistance, perfluoroether rubber can show its excellent stability and excellent tolerance to almost all chemicals in the environment of ethers, amino compounds, ketones, oxidants, organic solvents, fuels, acids, alkalis and so on.

◆ intuitive swelling test

Chemical attack can destroy the molecular chain or cross bridge of ordinary rubber, resulting in volume expansion, resulting in unmatched O-ring and sealing part groove, resulting in leakage. Perfluoroether rubber products can withstand the attack of more than 1600 chemicals. After soaking in the mixed solution of toluene, acetone and dichloromethane for 6 months, the volume of perfluoroether rubber O-ring has almost no change, while other rubbers have been seriously deformed.

The results showed that perfluoroether rubber and fluorinated rubber were soaked in organic media such as acetone and toluene. After 16 minutes, fluorinated rubber obviously dissolved and swelled.
