   Abstract : Polyvinyl chloride (PVC) is used in a wide range of industrial areas. Manufacturing of PVC products requires use of additives, such as plasticizers, heat stabilizers and flame retardants. READ MORE

5. 3. Understanding corrosion protection mechanisms of nanocomposite polymer coatings on carbon steel : A combination of in-situ AFM and electrochemical studies

   Author : Jing Li; Jinshan Pan; Per Claesson; Herman Terryn; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer coatings; electrochemistry; nano; in-situ AFM; mechanism; corrosion protection; Kemi; Chemistry; Kemi; Chemistry;

   Abstract : Corrosion protection of carbon steel is crucial in today’s world and there is an urgent need to replace the hazardous compounds used with environmentally friendly anticorrosion coatings. In this European collaborative research project, new types of functional composite anticorrosion coatings for steel were developed with properties beyond the state-of-the-art using nanotechnology.

6. 4. Cellulosic Thermal Insulation with Improved Water Resistance and Fire Retardancy

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

   Abstract : 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.
