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

    Author : Anna Lundgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intumescent structure; flame retardant; Casico; silicone elastomer; polyolefin; effervescence; calcium carbonate;

    Abstract : 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. READ MORE

  4. 2. Phosphorylated Cellulose Nanofibrils : A Nano-Tool for Preparing Cellulose-Based Flame-Retardant Materials

    Author : Maryam Ghanadpour; Lars Wågberg; Jeffrey W. Gilman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorylated cellulose nanofibrils; flame-retardant; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The growing awareness of the need for a circular society and a circular chemistry has spurred the interest in using wood-based cellulose as a raw material for the preparation of new macroscopic devices and construction materials. The interest has been particularly focused on cellulose nanofibrils (CNF), which has led to the development of new material concepts through a nanoscale bottom-up engineering using renewable CNF.

  5. 3. Polyolefin Flame Retardant Cable Materials - Effect of Additives and Copolymer Structure

    Author : Linus Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Carbonate; Flame Retardant; Silicone Elastomer; Melt Viscosity; Ethylene-Acrylate Copolymer;

    Abstract : Fire safety of cables is becoming increasingly important as the use of electrical equipment steadily increases. Due to their excellent dielectric properties, polyolefin materials are widely used as insulating materials for cables. However, polyolefins are inherently flammable and need to be protected to meet the requirements on flame retardancy. READ MORE

  6. 4. Improved Flame Retardant Properties of a Halogen-Free Material for Cable Applications

    Author : Linus Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame Retardant; Melt Viscosity; Silicone Elastomer; Ethylene-Acrylate Copolymer; Calcium Carbonate;

    Abstract : Due to the large amount of electric equipment in our surroundings, fire safety of cable materials is becoming increasingly important. Because of environmental and health issues, much focus is on development of halogen-free materials. In this thesis, a halogen-free flame retardant material named Casico™ is studied. READ MORE

  7. 5. Flame-Retardant Cellulose Fibre/Fibril Based Materials via Layer-by-Layer Technique

    Author : Oruc Koklukaya; Lars Wågberg; Gero Decher; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame-retardant; cellulose fibre; cellulose nanfibril; layer-by-layer technique; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : According to an analysis conducted by the Swedish Chemicals Inspectorate in 2006, the approximate numbers of fire injuries per year in Sweden are 100 deaths, 700 major and 700 minor injuries.1 Observations also show that there has been an increase in the number of house fires during recent years.
