Our in-house compounds
Making use of our proprietary elastomer compounds, we produce window sealing systems, window profile frames, door profiles and portal frames for public transport vehicles. We vulcanize the rubber elements to fit exactly and deliver them to you either as single components or ready-to use systems, for example including electronic elements or window panes.
We supply a multitude of different industries:
- Hygiene and medical technology
- Aerospace
- Shipbuilding and port technology
- Commercial vehicles
- Building and construction
- Oil and gas production
- Defense
Our sealing systems are well known for their dependability and their durability. They are resistant against heat, cold and UV radiation.
In addition, they meet all relevant fire safety standards.
Seals – Our product portfolio
- Molded and extruded parts
- Injection-molded corners
- Rubber-metal components
- Fabricated articles
- Special applications
When metal components are used, these receive the appropriate preconditioning to ensure optimal bonding with the rubber elements.
With our wide range of products and extensive activities in different industries and in countries around the world HÜBNER achieves unique synergies. Customers trust HÜBNER's proven expertise and bring rubber production requirements of all sorts to our engineers.
Because you can always rely on HÜBNER.
Product development to meet the highest standards
HÜBNER responds to individual customer wishes with speed and innovation. In the field of research and development our team already has 600 rubber compound recipes at its disposal. You too can benefit from our many years of experience, the most modern software in the industry and our in-house machine tool engineering.
We will be pleased to fulfill your specific product requirements – including special wishes such as color variants, fire resistance as well as compounds meeting specifications for atomic, biological and chemical (ABC) resistance. Our stringent material testing is conducted directly at HÜBNER facilities – mechanical and thermal testing, surface structure measurements, color measurements and flammability testing.
Corner injection molding process for even higher resistance
Rubber frames that need to have a high resistance to shearing effects are produced using the latest corner injection molding processes. In this way, we achieve a clean transition between the extruded profile and the shape-molded corner with with both radial and rectangular corners. We also use this technique for connecting hollow chamber profiles and profiles with varying diameters.
Pneumatic seals for the most demanding conditions
For doors and vehicles that require an absolutely hermetic seal, we produce pneumatic sealing systems. The heart of the mechanism is a hollow chamber in the seal profile which is put under pneumatic pressure. Through the excess pressure in the chamber not a single drop is able to pass through the seal even under the most extreme conditions.
