   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thiocyanate; biocides; leaching; runoff; admixture; coatings; resin acids; blast furnace slag; toxic; fly ash; cement; tall oil; diffusion paints; concrete;

   Abstract : At a time of increased concern about environmental issues in the building sector, it is essential to know the environmental performance of different building materials. Knowledge of the possible release of hazardous substances in building materials is scarce, and these aspects have often been neglected in environmental assessment methods. READ MORE

5. 3. Green plasticizers for PVC - An investigation of renewable alternatives to phthalates derived from vegetable oils or wood industry products

   Author : Anna Bondeson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; Epoxidized vegetable oils; Crosslinking; Plasticizer; Heat ageing; Lignin.; Tall oil fatty acid;

   Abstract : Polyvinyl chloride (PVC) is a very versatile thermoplastic because of its ability to solve a broad range of different concentrations of plasticizer. Phthalates are still the most commonly used plasticizer in PVC, but due to public opinion and legislation against phthalates there is a demand in the market for both old and new phthalate free plasticizersProperties of epoxidized oils of soybean (ESBO), canola (ECO), sunflower (ESFO) and safflower (ESAO) were investigated to determine their suitability as plasticizers.
