Formulation and Process of Rubber Molded Product There is no such thing as a particular rubber material. There is a custom formulated product that is produced is such a way that the required rubber product is manufactured as per the application need. Compared to other materials like steel or plastic, rubber is a far more complex material and many components are used which undergo chemical reaction during the vulcanization process and finally used in the manufacturing cycle. Rubber molding process is actually an art where the following challenges to be considered. Chemical: Rubber is often required to withstand a wide number of chemicals. For instance, when rubber is used in motors or generators, it must be resistant to oils and gasoline. In some industrial applications, rubber needs to be resilient to harsh fluids like cleaning solvents, acids or alkalis. Without proper formulation, a rubber compound could actually get crumbled or dissolved when faced with these corrosive substances. Environmental: Not only does rubber has to withstand corrosive chemicals, and remain flexible, but it also has to perform in temperature extremes. For example, a car with sealing O-Rings in its engine will be subjected to freezing temperatures in a very cold country and the same O-Rings have to withstand a normal temperature in a warm country. Considering the above challenges, the formulation of the rubber molding process starts. The first step in rubber formulation is to prepare the requirements relating to conditions that the rubber will need to bear. The conditions include the mechanical/dynamic


requirements, besides the chemical and environmental factors. After thoroughly understanding all the requirements, a rubber formulation chemist can actually come up with different components to create the compound. It is difficult to come up with the exact formulation that will optimize a given performance for an application. Before the actual product is developed, the following factors are tested. Fluid immersion Temperature stressing Tensile strength Flex-cycling Elongation testing Ozone aging and Weathering Flexible: Rubber can take up many shapes and deformations in its applications, which is not the case in other materials. Hence, rubber should be able to maintain its properties through a long period, infact, a lifetime of dynamic stressing. Rubber needs to be resilient enough to do its work even after being stretched, compressed or twisted hundreds of times. This testing gives some idea of the product's performance. Once the tests are done, the acceptability of the rubber formulation is considered. Once the product is developed and tested, it is ready for manufacturing. Thus manufacturing of Rubber Molded Product


is not an easy task. That is why it is rightly been said that "rubber molding is an art rather than a science". Ref: industrialrubbergoods.com/articles/rubber-moldingformulation.html
