Make Your Rubber Products Crack Proof with Ozone Testing

Rubber is a very useful material that is used in almost all the industries to produce various types of products like tires, seals, gaskets, footwear, household products, industrial material, fasteners, etc. These products are manufactured by processing the natural rubber into vulcanized form. As the natural rubbers are very soft and fragile in nature, they can’t be used for production process of any material whether domestic or industrial. Hence, to make the rubber useful, the process of vulcanization is followed. Vulcanization of the rubbers is the process through which the physical and chemical properties of natural rubber are changed to some extent by adding sufficient amount of sulphur to it. This automatically changes various properties of the Sulphur and makes the rubber hard to use for production purposes. The amount of adding sulphur is not fixed; this depends on the application for which the rubber is needed.


After the process of vulcanization, rubber is sent to different industries to proceed for further manufacturing. When the rubber material goes through the rigorous manufacturing process, the strong and high-quality of rubbers products will be obtained that are used for various industrial purposes as well as for domestic purposes. The rubber compounds are used for various crucial applications like aircraft, aerospace, defense equipment, and many more. Hence, the rubber material which is used to manufacture these products must be of topmost quality and utmost grade. This is only possible if proper quality testing techniques should be followed while testing the quality of the rubbers. This can be done with the help of high quality of testing instruments. The testing devices that are used to verify the quality of the rubbers must be of best quality. One of the best testing instruments which are used to check the quality of the rubbers is “Ozone Test Chamber“.


The rubber goods frequently face the harsh working conditions that also have the presence of Ozone layer in it. The ozone is a very harsh has that adversely affect the quality of the rubbers and the mechanical properties of the rubbers products. This forces the manufacturers to test the effect of ozone on any rubber product. The ozone chamber is an extremely accurate testing instrument which is used to measure the impact of ozone concentration on various properties of the rubbers. It is a closed cabinet that produces original ozone environment to assess the effects of the ozone on the properties of the rubber compounds accurately.

About Some Knowledge of Rheometer

A rheometer is a device that was developed to measure how a liquid’s suspensions or slurries flow when force is applied to it. Many fluids can be tested with a rheometer when a single numerical viscosity value cannot determine them due to their components. A rheometer can also be used to discover the additional parameters and values that a viscometer can correctly measure. In other words, the rheometer tests a fluid’s rheology.


There are two types of rheometers that test a liquid’s rheology. There is an applied shear stress/strain option that is known as a rotational/shear rheometer. It is designed to measure native strain and can provide valuable data for measuring the liquid’s shear stress. The other type is a native stress controlled rheometer. It is used to control the application of a defined stress/shear that measures the strain of the shear as a result. But we only talk about shear rheometer series in this article.


What does Rheometer Mean?


The word Rheometer comes from a Greek word that means “measuring flow.” Therefore, the device created for this task was dubbed the rheometer. The word rheometer has historically been used to refer to different types of measurement devices. First, it was the name of the device that measured electric current until a new word was created to replace it (the galvanometer or ammeter). It was also the name of the medical tool used to measure blood flow. Rheometer was also the name of the civil engineering tool used to measure water flow. After the term rheology was defined, the tools previously referred to as rheometers were renamed.


Rheometers that Measure Shear


There are a wide variety of rheometers that measure shear in different ways. Though these have slight differences, they generally offer the same kind of information. The following are the available shear rheometers:


Pipe or Capillary – The pipe or capillary rheometer is designed to measure a liquid that is forced through a tube. This makes it possible to measure a constant cross section and dimensions that define the laminar flow of the fluid. Shear rate can be determined via the dimensions measured from the liquid’s flow rate and pressure drop, which are converted into the proper shear stress measurement.


Rotational cylinder – This is a cylinder and a one-plate measuring system, where the liquid is placed within the small ring space of a cylinder that is inside another. The cylinder is then rotated at a speed that makes the shear rate measurable. The torque of the force that is needed to turn the other cylinder is then used to convert the shear rate into shear stress. A modern day rotational cylinder apparatus may be able to spin at 600, 300, 200, 100, 6 & 3 RPM to measure the shear stress of fluids. Modern day options can also be programmed to measure these values at changing intervals, which can measure important time based readings.


Cone and plate – Here, a liquid is placed on a flat plate as well as a short, shallow cone that is placed on top. The cone is typically at a one degree slant. The plate is rotated and the force exerted on the cone is measured. Oscillating versions of this rheometer can measure additional values such as elasticity.

Importance of Rubber and Ozone Test Chamber in Industries

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 – ozone test chamber is required at this moment.


An ozone test 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 test chambers help in detecting the amount of change that takes place in a testing sample after it is exposed to ozone in the ozone test 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 viscoelastic 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.

Understanding Tensile Tester

Tensile tester is a machine that is used to measure ultimate tensile strength, elongation and reduction in the crossectional area of the material by subjecting it to axial force. The test is carried out to know how a material will react to different type of forces in the field so that weakness are pinpointed and necessary remedial measures are taken to prevent failure in manufactured goods.

A Universal Tensile testing machine, popularly known as UTM, is widely used by laboratories to test the tensile and compressive strength of the materials. The main purpose of this tensile tester is to establish maximum stretch limit of any material, before its breaks. It is used to test strength of various materials like rubber, plastic, steel etc, which are used in manufacture of different types of goods.

The Universal tensile testing machine helps to establish the ductility of metal. This property of metal allows it to retain its original shape after the load is removed, without any alteration. Through testing one can know the range of elongation and breaking point (point-of-no-return to original shape). Tensile strength testing machine helps manufacturers of industrial raw materials, semi-finished and finished goods get right information about the elongation, elastic limit, yield strength and yield point of their materials and avert any operational failure due to undetected weakness in the material. This machine ensures satisfactory compliance to industrial safety regulations and manufacturing practices.

The UTM has two crossheads, one is adjusted to accommodate the length of the specimen and the other one is hydraulically or electromagnetically driven to produce the tensile strain on the specimen. The machine generates enough force to fracture the specimen, in quick or slow way to mimic the action of force in actual field conditions.

Tensile tester measures minute change in dimensions to show exact behavior of the material under stress. This helps to build reliable testing report so that inherent weakness in the material are accounted and taken in consideration during the manufacturing process. Besides this tensile tester helps quality control engineers to ascertain the tensile breaking point or yield point of their finished goods before they are sent into the market. There are many types’ models of Universal tensile testing machine available in the market; however they generally have few common points that are mentioned below:

  • Anti-Backlash system
    • Electromagnetic or Hydraulic powered movement of one crosshead
    • Emergency stop through rocker, mechanical switch or computer
    • Crosshead guidance system
    • Quick disconnect load cell and fixture system

There are many suppliers of tensile testing machine in market and price of the tensile testers varies according to the technical features offered, models and the functionalities. It is in best interest of the user to thoroughly analyze the different models, their price and ascertain that how a said machine can benefit them in optimum manner.
