Compounds tailored for wireless electronics.RTP (1) (Rapid Transport Protocol) The protocol used in IBM's High Performance Routing (HPR) system. (2) (Realtime Transport Protocol) An IP protocol that supports real time transmission of voice and video. Co. in Winona, Minn., says it is a pioneer in formulating compounds for encapsulating embedded antennae for wireless devices that area third to half their previous size and weight. Miniaturizing antennae requires raising the dielectric constant dielectric constant n. See permittivity. of the plastic compound in order to increase absorption of electromagnetic signals at lower wavelengths. The dielectric constant of most plastics is less than 2, but RTP incorporates conductive ceramic powders to boost that to between 2 and 12. RTP also starts with resins like syndiotactic A syndiotactic macromolecule in polymer chemistry is a tacticity essentially comprising alternating enantiomeric configurational base units which have chiral or prochiral atoms in the main chain in a unique arrangement with respect to their adjacent constitutional units. PS (Dow's Questra) and PP, which have higher dielectric constants than most plastics. The new compounds are said to enhance signal transmission and reception. They reportedly can also meet requirements for flame retardancy, impact and wear resistance, color, electroplating electroplating: see plating. electroplating Process of coating with metal by means of an electric current. Plating metal may be transferred to conductive surfaces (e.g., metals) or to nonconductive surfaces (e.g. , and EM1 shielding. Tel: (800) 433-4787 * PT Direct: 116PH |
