Rubber is a versatile material that is used in various industrial and domestic applications. All across the globe, the natural rubber is extracted from trees. The natural rubber is very soft and is in a thick liquid form. Rubber of this kind does not have many usages. The natural rubber is purified and gives an end product called polyisoprene. Rubber of this kind can also be synthesized by artificial methods. The synthetic rubber has extensive industrial usage as compared to natural rubber.
They are used for making tires, household products, tubes, industrial hoses, industrial cushions and so forth. Rubber also has a high usage in the construction field for flooring, matting, etc. The material is also used extensively in manufacturing medical products such as surgical gloves, catheters etc. the molecular structure of rubber consists of a long interlinking polymer chains that make it ideal for usage in a vast variety of industries.
The Natural rubber is not completely fit for industrial usage hence the process of vulcanization is used to increase the properties and strength of the material by adding sulfur to it. After, vulcanization the strength of the material is increased significantly, making it fit for industrial usage.
As vulcanized rubber has extensive usage in industries, it is essential to test the various properties of the materials and the end product so that the manufacturers can ensure the best quality provided to their customers. There are many different properties of rubber that need to be tested before commencing the manufacturing process. This helps in avoiding enormous rejection of end products. These tests conducted on rubber include tensile strength, compressive strength, the effect of aging, etc. An important testing procedure that is conducted on rubber materials is testing under ozone environment.
An ozone chamber is used for testing the effects of ozone on a rubber product or material under controlled conditions. When the rubber is exposed to ozone for a longer time, there are significant changes in the properties of the material such as breaking strength, tensile strength, etc. The ozone chamber helps in detecting the amount of change that takes place in a testing sample after it is exposed to ozone in the ozone chamber.
Another major testing instrument that is used for quality testing of rubber is the shore hardness tester. A shore hardness tester is used to test the hardness of a rubber material under specific load. This helps in determining the visco-elastic properties of the materials and helps in predicting its suitability for a certain usage. The use of rubber products in today’s industrial scenario is inevitable, but proper testing procedures are essential to make sure that the best quality products are provided to the customers.
