In the group of sealing materials, STS7999 stands for excellent sliding and sealing properties thanks to its low coefficient of friction. Its graphite base makes it a hard sliding material and the ideal choice for sealing rotary kilns and rotary drum furnaces, for example. It has good self-lubricating properties and a very high temperature resistance. It safely retains the necessary properties, even at operating temperatures of up to 800 °C.
|Mean coefficient of friction (dry)*1||0,10 µ|
