Rubber has become one of the most widely employed polymers worldwide despite its mix of unique properties, particularly great compression and tearing strength coupled with remarkable strategic flexibility, that made it a vital and indispensable material for the creation of larger tires. Rubber is the seal material used in machine elements the most frequently. A catastrophic accident could occur if the rubber seal in structures that seal fails. Sealants inhibit the passage of hydraulic fluid while removing scratches caused by the piston's immediate communication with the inside surfaces of the engine cylinder. It is crucial to propose higher requirements for rubber's constancy owing to the demanding workplace and the inconvenience of changing it. Throughout the period of its existence, rubber can grow less reliable due to a variety of circumstances, such as load changes, external conditions, and heat treatment. Heat treatment of polyvinyl rubber has been employed in the present investigation. Four distinct factors, including curing period, curing temperature, post-curing temperature, and post-curing duration, were varied during the heat treatment. Specimens have been heat-treated depending on such variables. The universal testing machine, tear testing machine, and rheometer has been employed to examine the compression properties, tear behavior, and rheometric qualities. Results showed that the compression strength, tear strength, and rheometric parameters are significantly impacted by the heat treatment. The samples that were cured at 150°C had better compression set properties as compared to samples cured at 170°C. It can be observed from tear results that the tear strength for both specimens was 18 N/mm. The outcomes of the rheology test demonstrated the compound's favorable vulcanization capabilities. The rubber compound has plateaued after reaching its maximum torque. This shows that it has grown as strong as it can be and is not weakening as it cures.
