Flexometer Series (ASTM D623 & ISO 4666 Rubber Heat Build-up Tester)

Analyzing Hysteresis & Heat Build-up in Elastomers

When rubber compounds are subjected to rapid, cyclic compression, internal friction causes a rise in temperature—a phenomenon known as Heat Build-up. EKTRON TEK's Flexometer Series is engineered to simulate these dynamic fatigue conditions, providing critical data on a material's energy loss and structural durability.

  • Global Compliance: Strictly adheres to ASTM D623 and ISO 4666 industrial standards.
  • Performance Metrics: Predicts rolling resistance in tire compounds and blowout resistance in industrial rubber.
  • Intelligent Analysis: Real-time detection of thermal history, deformation ratio, and dynamic fatigue properties.

Frequently Asked Questions: Flexometer Testing

How does a flexometer help in tire compound development? ▼
By applying a constant load and high-frequency compression, the flexometer measures how much heat a compound generates under stress. In the tire industry, this data is used to calculate Rolling Resistance. A compound with low heat build-up typically offers better fuel efficiency and longer tire life due to reduced thermal degradation.
What is the "Blow Out" test in rubber analysis? ▼
The Blow Out test is an extreme version of the heat build-up test. The sample is compressed until the internal heat reaches a point where the rubber physically fails or decomposes. This identifies the absolute thermal safety limit of a compound, which is vital for heavy-duty truck tires and vibration isolators.
