Rubber gaskets
The invention of rubber technology dates back to 1839, when Charles Goodyear obtained rubber from the cold vulcanisation of rubber using sulphur. The following years saw the development of rubber technology and the modification of additional raw materials in order to obtain the desired physical and chemical properties. Thanks to the fact that today's rubber is highly elastic and can be resistant to weather conditions, lubricants, ageing or inert to small amounts of inorganic alkalis and acids, its use is wide. It is most commonly used to make all kinds of rubber sealstyres, footwear, toys and many other rubber products. Rubber is also used to cover all kinds of metal parts, such as shafts, rollers, which are used, among other things, in production machinery.
Types of rubber seals
One of the most complex products made from rubber is gaskets. In simple terms rubber seals can be divided into injection moulded and extrusion gaskets. Injection moulded gaskets can be flat or have many different shapes with complex cross-sections. Their shape is limited due to the possibility of making a suitable mould and the high cost. Thanks to the extrusion method gaskets can be of virtually any shape, allowing them to be used in many industries. Our company specialises in the production of sewer and water supply gaskets. We produce trapper gaskets, for concrete pipes and concrete coils, for corrugated pipes and pressure pipes, IN SITU gaskets, telescopic cuffs and more.
Take a look at our injection-moulded gaskets and rubber profiles.
Gaskets for pressure pipes
Pressure pipe seals manufactured by M.O.L. Romgum are made from an SBR-based rubber compound with a hardness of 60° IRHD. The construction of this gasket, which is made up of three lips, is responsible for the tight connection of the pipes. The first lip of the gasket has the task of stabilising the pipe in relation to the gasket, the second layer protects against contamination, while the third lip is responsible for optimal pipe connections. These seals are most commonly used for pressure pipes and fittings.
Rubber profiles
The rubber profiles produced by our company are made from a rubber compound based on NBR, SBR and EPDM rubbers. Most commonly, rubber profiles are used as sewer gaskets. Due to the production method, in the case of rubber profiles it is the extrusion method, the profiles are used wherever, due to their shape or cross-section, seals cannot be made on injection moulds.
Sealing sleeves
The telescopic cuffs manufactured by our company are made of a rubber compound based on SBR rubber. SBR rubber is characterised by high resistance to abrasion, low and high temperatures and frequent changes in weather conditions. Sealing gaskets are used in plumbing and drainage networks. As a manufacturer of seals, we are able to produce telescopic cuffs according to customer requirements.
Application of rubber seals
As mentioned earlier, gaskets are one of the most widely used rubber products. Rubber gaskets They provide excellent protection against dust, dirt, moisture and liquids and are very good at damping vibrations. All these properties give gaskets many positive qualities, making them used in virtually every industry.
Gaskets can be found in:
- cars,
- bicycles,
- household goods,
- pipe connections,
- watches,
- armature,
- electronics,
- other machinery and equipment.
Seals are used wherever there is a risk that an unwanted substance could adversely affect the equipment or process.
EPDM, NBR and SBR rubber are the most commonly used rubbers for gaskets. Depending on the rubber chosen and the additional raw materials, gaskets can operate in a wide range of temperatures and environments. Gaskets made by extrusion, or so-called rubber profiles, have also found use as transport protection for windows and glass, for example.
