Modern-day society would not function without polymer materials, or rubber and plastics as they are commonly known. Machines, tools and accessories need sealing, damping and protecting using a material that is durable, elastic and tough.
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.
