   Författare :Chao Zheng; Monica Ek; Dongfang Li; Lennart Salmén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bio-based; Cellulosic; Fire retardant; Thermal insulation; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Sweden is one of the largest countries by area in Europe, and almost 70% of it is covered by forest. These abundant forest resources benefit the Swedish bioeconomy, but the pulp and paper industry is facing the challenge of a decrease in the demand for printing paper due to a significant shift to electronic media; therefore, it is a priority to use pulp to produce alternative value-added products, such as thermal insulating materials in buildings.

3. 2. Reaction to fire performance of wood and other building products

   Författare :Lazaros Tsantaridis; KTH; []
   Nyckelord :building products; charring of wood; cone calorimeter; fire retardant treated wood; fire tests; ignitability; mass loss; rate of heat release;

   Sammanfattning : The theme of this thesis is the reaction to fire performanceof wood and other building products, andparticularly thematerial fire properties time to ignition, rate of heat releaseand smoke production. These properties have been measured by asmall-scale fire test method, the Cone Calorimeter, andpresented for different types of building products. LÄS MER

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

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

   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

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

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

   Sammanfattning : 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.

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

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

   Sammanfattning : 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. LÄS MER
