SBR | shock resistance,performance well in adhesion and sealing |
Silicone | widest operating temperature range,performance stably in high and low temperature |
VT/FKM | excellent resistance to high temperature and a broad range of chemical,permeability and compression set are excellent |
HNBR | thermal stability and oxidation resistance |
IIR | low permeability rate and good electrical properties |
FVMQ | widest operating temperature range,performance stably in high and low temperature,good resistance to oil and fuel |
How to select the right material ?
It's important to select the right rubber material for the applicaiton and the environment. Most rubber materials will have the flexibility to be used in rubber bellows applications - Beike Sealing. can work with you to identify the best, most cost effective material for your application.
What medium will contact when using, oil, chemicals...?
What is application temperature?
Dynamic seal or static seal?
Surface seal or shaft seal?
Remark: If still not sure, suitable material could be suggested according to WORKING CONDITION, for example: working temp. and working medium ( oil, seawater, solvent and so on)
.
.
It is used to install on various mechanical equipments. It can seal under static or moving conditions under the specified temperature and pressure and different liquids and gases.
