  • Silicone elastomers have a unique combination of properties not found with organic elastomers, such as stability over a very wide temperature range, good electrical properties and environmental resistance, no smell or taste, high biocompatibility, low softness without plasticizers, and high colourability and transparency. (chemtec.org)
  • In order to qualify as a thermoplastic elastomer, a material must have these three essential characteristics: The ability to be stretched to moderate elongations and, upon the removal of stress, return to something close to its original shape Processable as a melt at elevated temperature Absence of significant creep It was not until the 1950s, when thermoplastic polyurethane polymers became available, that TPE became a commercial reality.

  • The cure schedule is a combination of temperature and time to which a heat curing silicone material must be exposed for "complete" curing. (nusil.com)
  • A thin sheet of elastomer will cure much quicker than a thick section as the appropriate cure temperature will take longer to achieve in the core of the silicone sample) Special care must be taken to eliminate the presence of contaminants that might have a negative impact on the catalyst (see Poisons below).

  • Materials
  • Silicone elastomers are important materials for many application areas such as automotive, electric and electronics, domestic appliances and medical. (chemtec.org)
  • This review is packed with details on specific silicone materials, containing over 50 tables of information together with useful graphs. (chemtec.org)
  • Process
  • A newer technology, however, enables this metamorphosis to occur "on the fly" during the extrusion process. (mdtmag.com)
  • Geo-Trans is a patented process that enables the cross-sectional profile of a silicone tube to change "on the fly" during extrusion. (mdtmag.com)
  • The process was invented and patented by Specialty Silicone Fabricators (SSF) in 1996. (mdtmag.com)
  • Multi-lumen continuous extrusions- The Geo-Trans process can easily split two or more lumens off a center lumen or merge two lumens into a single lumen-all in a single continuous extruded tube. (mdtmag.com)
  • high
  • Whether your part is a micro extrusion, co-extrusion or made from a custom compound you can count on Microspec's experience and expertise to deliver high quality and precision extruded parts every time. (medicaldesignbriefs.com)
  • Midway through the decade, Pawling diversified into mill mixing and extruding of high-purity silicone (then an elastomer) for electrical wire and cable insulation. (wikipedia.org)
  • Electrical
  • Speciality silicones are continually being developed to meet specific application requirements, for example, standard silicone is a good electrical insulator and is used in cable coverings, however, conductive silicones are now available. (chemtec.org)
  • include
  • Concepts for tomorrow's Geo-Trans include spiral tubing configurations and extrusions where integral lumens stop and start. (mdtmag.com)
