Applications of Rubber in Special Building Constructions

EPDM Roofing

EPDM is in Europa intussen een algemeen geaccepteerd dakbedekkingsmateriaal geworden. Deze presentatie geeft de ontwikkeling van EPDM dakdekking aan vanaf het ontstaan tot en met het succes en marktaandeel van vandaag. De technische ontwikkelingen en productie wijzen worden toegelicht. Naadverbinding, prefab, vliegvuurbestendigheid, levensduur zijn kernwoorden.

Rubber Springs to Protect Buildings

As modern cities become more densely populated, it is common practice to develop sites that are near or directly above roads and railway lines. Despite these hostile conditions, government legislation and client

Ultra Low Viscosity Polymeric Additives

For years, processability of compounds has generally been improved through use of plasticizing oils and process aids. In many cases this solution has been inexpensive and easy to implement. However, in some applications, the use of these materials can have deleterious effects, necessitating the use of a compound with little or no plasticizer, which subsequently has poor processing characteristics. This is especially true when compounding for very demanding EPM or EPDM applications. Attempts are sometimes made to use the lowest possible viscosity EPM or EPDM reactor grade, but that often results in a difficult balancing game between attainment of mechanical properties and acceptable processability. Several unique ingredients have been introduced to the rubber market to provide a viable solution, but many are in liquid form, and as such are difficult for mixing plants to handle; can have compatibility problems with EPM or EPDM; and can be cost prohibitive. In 2008, DSM Elastomers installed a state of the art reactive extrusion (REX) line in Triunfo, Brazil. The technology provides a route to manufacture ultra low viscosity EPM and EPDM.
