A good seal should correspond to not only size and shape, but also properties. They, in turn, must correspond to the environmental factors in which the product will be used. Not all types of rubber are resistant to the same substances or temperatures. So how do you choose a durable seal when it is in contact with acids? The most popular types of technical rubber
Different industries did not do without the use of various sealing materials. Most often, they are made of rubber mixtures during volcanization, the most important of which are SBR, NBR and EPDM. Due to different chemical compositions, they have different properties. However, they are united by durability in terms of physical and chemical properties. Therefore, when choosing a specific material for gaskets, it is necessary to pay attention to the resistance of this type of rubber to individual substances, as well as the temperature range in which it preserves its attributes. This looks as follows: NBR - resistant to lubricants, motor oils, propane, butan, hydraulic fluids, alcohols and temperatures up to 100 degrees Celsius; EPDM - acids and esters are neutral, and, in addition, it retains its properties up to 130 degrees Celsius; SBR - is not damaged by alkalis, alcohols and acids and can be used at a temperature of up to 80 degrees Celsius. Therefore, it is best to choose EPDM elastomers for the production of acid -resistant gaskets. In addition to the substances mentioned above, they are also resistant to water pair, oxygen, ozone, ultraviolet radiation and thermal aging. They are also not subject to deformation or damage due to friction. The manufacture and use of seals from EPDM
Products of this type are most often manufactured in the process of extrusion or casting under pressure. They are also obtained by pressing in forms for volcanization or simply cut out of the EPDM rubber plates. Thanks to these methods, you can get seals of various shapes and sizes, for example, in the form of classic sealing rings or cords. Moreover, in some cases simply these plates are also used. Elastomer seals are used mainly in the automotive industry., Foods or in the production of carpentry or automatic washing machines. EPDM rubber is very often used to create waterproofing roofs and terraces. This material is ideal, in particular, for the manufacture of seals working in a static environment.
