Testing of elastomers
Elastomers are characterized by high elasticity, ductility, and chemical resistance. These properties make elastomers ideal for seals, shock absorbers, and other applications, and they are used in a wide range of industries. The versatility of elastomers ranges from industrial to medical applications.
Why are elastomers tested?
Elastomers must be tested to ensure that they meet the specific requirements of their respective application. These tests may include physical, chemical and mechanical tests to verify resistance to various environmental conditions, such as temperature, pressure and chemicals. These tests ensure that the elastomers retain their elasticity and functionality over their expected lifespan and that there are no premature failures that could lead to safety risks or costly repairs. In safety-critical areas, such as automotive or medical technology, such tests are particularly important as they directly influence the reliability and quality of the end products.
Typical applications of elastomers as sealants
Elastomer seals are used in many areas to provide an effective barrier against gases, liquids and dust. The main areas of application are window and door seals for heat, sound, wind and water insulation, the automotive industry for door and window seals, engine seals and seals in fluid systems. In the construction industry, they are used to seal facades, roofs and leaking masonry and for sound insulation. In mechanical engineering, elastomer seals are used to prevent leaks and to reliably seal machines and devices. In sensitive areas such as the food and pharmaceutical industries, the elastomer sealing profiles are used to meet the high hygiene requirements due to their resistance to certain media.
Elastomers can be used in well casings to perform various functions. Well casings are used in wells to stabilize the well diameter, seal the well and facilitate drilling progress. Elastomers, also known as rubber seals or rubber compounds, are used in various places:
- Sealing functions: Elastomers are used as seals in well packers to prevent fluids from entering or exiting the well. These seals help maintain the integrity of the well and keep out unwanted fluids, such as water or gas.
- Flexibility and adaptability: Elastomers are able to adapt to different well geometries due to their flexible nature. This is particularly important as wells are often shaped in complex ways. The elastomer seals ensure that the casing is well sealed and adapts to varying downhole conditions.
- Vibration protection: elastomers can also help absorb vibrations and shocks that may occur during the drilling process. This helps to extend the service life of the shaft liner and improve the stability of the borehole.
The choice of elastomer materials depends on the specific requirements and the conditions in the borehole.
