Rubber is a very versatile material which can easily be molded into any possible shape and can be of any size. The rubber products are widely used for a many different applications in a variety of industries. The properties of rubber such as flexibility, high elasticity, tensile strength, compressive strength, etc. are best for usage in several critical applications such as gaskets, mechanical components, and seals and so forth. Most of the Rubber is obtained from plants in most of the areas of the world. The rubber obtained from the plants is not very useful as it is very soft and sticky. The desired level of hardness and strength of the products made from rubber can be obtained through the process of vulcanization. It is the process of adding sulphur to the natural rubber and makes it hard and stronger. In this way, the natural rubber can become usable for many different applications.
The manufacturers of rubber products need to ensure that the products manufactured by them are of best quality and able to satisfy the expectation of the clients. If the quality of the rubber products is not ensured, then it can lead to many horrible consequences as the rubber products are usually used for many critical applications. The rubber products need to go through rigorous testing procedures that are designed to evaluate the quality of the products accurately. A major test that must be commenced for rubber products is the flex test. The flexing is the phenomenon, in which the rubber is subjected to a continuous flexing. Due to the continuous flexing, the surface of the rubber product develops many cracks which eventually lead to its reduced strength and failure. Flex testing is an ideal testing procedure which is used by the manufacturers to ensure enough resistance of rubber products against flexing effects.
The testing procedure is conducted by placing the test specimen of a rubber product between two clamps and then horizontal; flexing is applied to it. The flexing procedure replicates the actual flexing conditions on the test specimen. The testing instrument that is used for the test is called the DeMattia flex tester. The DeMattia flex tester easily replicates the actual flexing conditions and provides a best quality evaluation of the products. After the test procedure is completed, the test sample is taken out, and the surface of the specimen is analyzed for development of any sort of cracks or deformation on the surface. With this testing procedure, the manufacturers can make essential changes in the manufacturing process to enhance the flexing resistance of the rubber materials and products.
