Laboratory-Tested Performance for Confidence

Our diaphragms undergo comprehensive testing in accredited laboratories to verify their durability and performance. For example, our product has been tested by DVGW Laboratory in Germany according to the EN549 standard, an industry benchmark for rubber products used in gas and other industrial applications.

Testing Highlights:

• Temperature Resistance: The diaphragm has been tested at temperatures as low as -40°C and demonstrated exceptional flexibility and performance even under extreme cold conditions.

• Chemical Resistance: Our diaphragms have been soaked in a variety of reagents such as N-pentane and Toluene, with test results showing minimal weight change, demonstrating superior resistance to chemical degradation.

• Durability: The tests show that after 72 hours of exposure to extreme conditions, the diaphragm's weight change remained within acceptable limits, ensuring that the material retains its structural integrity over time.

Test Results Summary (Excerpt from the Lab Report):

• Before Soaking: 100% (Reference weight)

• After 72-Hour Soak in N-pentane + LL10: Weight change of -2.3%, well within the industry standard.

• After 168 Hours at 40°C Drying: Weight change of -8.4%, proving the diaphragm's stability even after prolonged exposure to heat.

These results are an assurance of our product's ability to perform in the most demanding conditions, offering reliable sealing performance for gas, oil, and water applications.
