How to Measure the Resistance of Rubber to Cracking?

Rubbers are used in numerous applications to produce a different type of rubber products. Rubber components have the ability to bear frequent flexing without initiating the cracks as they are highly elastic in nature. The flexing property of the rubber is quite important to judge mainly when a manufacturer needs to use such kind of products in different circumstances where they have to tolerate continuous flexural forces. The De-Mattia Flex Tester is the best and widely used testing machine which is used to measure the resistance of rubber products to cracks which are initiated on the materials either by bending or by extending the sample under different conditions. The testing device is provided to measure the crack formation in rubber when placed under continuous flexing conditions.

De- mattia Flex Tester by Presto for Rubber Testing

Presto Stantest, a foremost manufacturer of rubber testing machine, offers high quality of De-Mattia Flex tester to test the quality and strength of the rubbers. The testing machine produces continuous flexing with a particular condition of mode, degree and speed of flexing in the testing laboratories on a sample of the rubber.

Standard Operating procedure of De-Mattia Flex Tester

The testing instrument provides full-fledged information regarding the resistance of the vulcanised rubbers to cracking when placed under repeated flexing. The cracks in the samples are developed on the rubbers where the stress is applied to the materials when they are placed under continuous flexural forces. If the specimen is already cracked from a particular area, more cracks are developed, or the cracks are enhanced in the opposite direction. The testing machine is used to test at least six samples simultaneously. The device is provided with digital control panel and counter that provide highly precise and accurate test results.
