  1. 1. Low smoke halogen-free materials for wire and cable applications

    Författare :Anna Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame retardant; calcium carbonate; calcium silicate; Casico; polyolefin; effervescence; intumescent structure; thermal degradation; silicone elastomer;

    Sammanfattning : Fire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start a fire and/or spread one. Traditionally, materials containing halogen have been used as primary insulation in low voltage power and telecommunication cables and most cables used today therefore contain halogen. LÄS MER

  3. 2. Mechanism of a polyolefin based effervescent flame retardant material

    Författare :Anna Lundgren; Chalmers tekniska högskola; []

    Sammanfattning : ABSTRACTFire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start and/or spread a fire. As a result of environmental and safety issues having to do with flame retardants based on halogens, much attention has lately been given to finding halogen free alternatives. LÄS MER

    Sammanfattning : Automotive seating has been under continous development since it was described for the first time in 1885. At that time one could read about a “padded leather bench seat sitting on springs mounted directly to the frame of a horse-less carriage”. LÄS MER
