LG-7040 Rubber Low Temperature Brittleness Testing Machine (multi-specimen)

Application of Equipment
The low-temperature brittleness testing machine is to determine the lowest temperature at which rubber materials do not exhibit brittle failure or the temperature at which half of the test pieces used in a test fail when impacted under specified conditions.Therefore, it is indispensable in the quality inspection of scientific research materials and products, and the control of the production process.
This equipment adopts cascade compressor refrigeration technology, uses the principle of heat balance and cyclic stirring, to achieve automatic uniform cooling and constant temperature of the specimen, and can fully meet the various temperature control indicators specified in the national standard GB/T229.
