At the beginning of the 1990s, the Trelle-borg Group comprised, in addition to theoriginal polymer operations (primarily rub-ber products), mining and metals opera-tions, mineral processing and trading activi-ties. During the latter part of the 1990s, theGroup was restructured and activities out-side the polymer operations were divested,creating a substantially changed Trelleborg.A number of significant acquisitions weremade during the years 1999-2000. Theacquisitions included the antivibration oper-ations (BTR AVS) of the British Invensyscompany, with sales of approximately > The...

The rubber tree (Hevea brasiliensis) requiresa warm and humid climate, which explainswhy rubber plantations are found in a zoneround the equator. Today, more than 90percent of all natural rubber comes from Southeast Asia. The largest producers areThailand, Indonesia and Malaysia, which together account for 80 percent of worldproduction. There are also rubber planta-tions in South America and Africa.Rubber trees grow to a height of approx-imately 20 meters. Tapping of the trees forlatex can begin seven years after sowing, andthe yield is highest when the trees are tenyears old. A rubber tree...

Chloroprene rubber (CR) ishighly suitable for products that are intend- ed for outdoor use or which could come into contact with oil or gasoline. A typical product is the outer layer of rubber in oil hoses. Butyl rubber is particularly suitablefor use in products designed to prevent gases from penetrating through the material. Among other applications, it is used in inner tubes for tires. > Rubber trees grow to a height of approximately20 meters.

CompoundFunction FillersCarbon black is a fine powder that is added to strengthen and fill the rubber. Chalk can also be used as a filler.Vulcanizing ingredientsOther substances in addition to sulfur can be used to influence the properties of rubber. The vulcanization speed is governed by accelerators and the process is initiated by activators.Aging inhibitorsVarious substances can be added to increase the lifespan of products. Examples are antioxidants and anti-ozonants,which protect against the effects of contact with the air.SoftenersSofteners are added to control product hardness and...

Environment-related activities within theTrelleborg Group are decentralized andbased on the individual operations of thedifferent plants. Formal responsibility for the environmental, health and safety issuestherefore resides within the various line orga-nizations. Site managers are key personnel inthis context and are required to managetheir operations in accordance with: ҕlegal and other requirements (e.g. custo-mer requirements),TrelleborgՒs environmental policy, environ-mental management manual, environmen-tal standards and position papers, requirements of ISO 14001.There are...

has been clarified, however, and we know thatthe greatest exposure to chemical particlestakes place during the first stages of produc- tion, i.e. the handling of raw materials, and the weighing and mixing of compound ingredients. Solvents are used primarily atthe coating and compounding stages. The vulcanization process itself generates vapor and gases containing hundreds of different substances, such as benzene, aromatic hydro-carbons and nitrosamines. Finally, during thehandling and warehousing of finished prod-ucts, gaseous substances are emitted.Trelleborg monitors the development...

Rubber has many properties that provide forbetter comfort and safety and an improvedhuman environment. Many of Trelleborgsproducts are used for the damping of noiseand vibration in cars and trains. Similarproperties are utilized in industrial applica-tions, e.g. the damping of vibrations inmachines and other equipment. Anotherimportant area consists of rubber seals forwindows and doors, where the environmen-tal gains lie in the saving of energy andreduction of noise.Rubber also has other favorable attributes,in that the material constitutes a durablemembrane that is impenetrable for both...
