Rubber Diaphragm/Homogenous rubber diaphragms

which is used in very low-pressure applications when the strength is not high required.  Homogenous rubber diaphragms offer similar functional advantages as fabric reinforced diaphragms and tend to be more economical for our customers not requiring a sturdy construction. This rubber diaphragm should have the advantages of heat resistance, medium resistance, pressure resistance, flex resistance and high sensitivity.The working temperature is generally -50 to +100 °C, and the working pressure is 0 to 2 bar.
