Rubber profiles

Rubber profiles are primarily used for sealing, protection, and cushioning in various industrial applications. They are manufactured according to the technical requirements of each project, taking into account the type of material, the profile shape, and the operating conditions.
In industrial environments, rubber gaskets are used to provide effective sealing against dust, water, or other external agents, as well as to protect edges and reduce vibrations. Choosing the right composition and profile geometry is essential for durability and performance.

Rubber seals are used in a wide range of industrial sectors, including machinery manufacturing, industrial equipment, the automotive industry, and technical systems where sealing and component protection are required.
Rubber profiles can be manufactured in a wide variety of shapes and sizes, depending on the application, and are designed for installation on flat surfaces, edges, or in dedicated pockets. The material’s flexibility allows for good adaptation to dimensional tolerances and ensures consistent sealing under various operating conditions.

Depending on operating requirements, the seals can be made of solid or cellular rubber, with each type offering specific properties in terms of stiffness, compression, and resilience. The choice of material depends on temperature, mechanical stress, and the operating environment.

Below are the main categories of gaskets manufactured by Vulcom, based on material structure and field of use.

Rubber extrusion profile type

Compact rubber profiles

Sponge rubber profiles

Compact rubber seals are used in applications where a tight seal and high mechanical strength are required. They are suitable for demanding industrial environments where the material must withstand wear, pressure, and temperature fluctuations.

Sponge rubber gaskets are characterized by their flexibility and compressibility, making them ideal for light sealing applications and for conforming to uneven surfaces. They are frequently used in applications where vibration absorption or compensation for manufacturing tolerances is required.

Rubber extruded profile application

Rubber seals are used in a wide range of industrial and technical applications due to their versatility and sealing properties:

  • industrial equipments
  • automotive and transport
  • construction
  • food industry
  • applications that require sealing and protection against water, dust, or vibrations (windows, doors, or various types of equipment).

How to Choose the Right Rubber profiles

Choosing the right rubber seals depends on several technical and functional factors:

  • the type of application and its intended use;
  • environment (temperature, humidity, chemical exposure)
  • the level of pressure and mechanical stress;
  • the type of mounting and the shape of the surfaces;
  • the need for flexibility or rigidity.

For complex applications, we recommend consulting our team to choose the optimal solution.

Custom-made profiles vs. standard profiles

Depending on the application requirements, rubber seals can be custom-made or selected from existing standard profiles.
Custom-made profiles are precisely tailored to the dimensions and operating conditions, ensuring optimal performance in specific applications.
Standard profiles are available from stock and offer a quick and efficient solution for common applications where standard sizes and shapes are sufficient.
