Polymers are long chains of molecules that serve as building blocks in rubber and plastics. While there is only one chemical variant of natural rubber, synthetic rubber is available in some 20 variants. Using additives and mixes of various types, and when combined with other materials, such as metals and textiles, polymers gain very different properties.
Trelleborg uses natural rubber in its large tires, springs and rubber bearings as well as its hoses, seals and coated fabrics. Synthetic rubber, such as styrene butadiene rubber (SBR) and isoprene rubber, has properties that are similar to those of natural rubber. In mixes, it is used as outer rubber in blasting hoses, oil and gasoline hoses, tires and more. Nitrile rubber (NBR) is often used with other types of rubber for added elasticity, abrasion resistance and ability to withstand low temperatures. Ethylene-propylene rubber (EPM/EPDM) is suitable for high temperatures and used for sealing profiles, hoses and more.
To seal is to fill a gap when joining two static or moving (dynamic) surfaces, thereby separating different media from each other.
- Seals for static and dynamic industrial applications
- Seals for control systems, brakes and engines in aircraft
- Coated fabrics for train bellows
To damp is to absorb energy, thereby reducing vibration and noise.
- Systems that protect against vibrations in rail vehicles
- Fenders for safe mooring in ports
- Systems that protect against vibrations in industrial applications
To protect is to help the environment, people, infrastructure and other assets to manage the impact from natural and man-made forces.
- Boots for drive shafts and steering applications in vehicles
- Agricultural tires that protect the soil
- Passive fire protection solutions on oil platforms
