2. 1. Biodegradable Thermoplastic Elastomers

   Author : Basse Asplund; Jöns Hilborn; Tim Bowden; Iskender Yilgör; Uppsala universitet; []
   Keywords : Chemistry; poly urethane ; poly urethane urea ; biomaterial; biodegradable; polymer; thermoplastic elastomer; haemocomatible; tissue engineering; biocompatible; Kemi;

   Abstract : A novel strategy for synthesising segmented poly(urethane urea) (PUU) without using a chain extender but nevertheless with the opportunity to vary the hard segment content has been developed. The strategy is based on amine formation from isocyanate upon reaction with water. READ MORE

4. 2. Thermoplastic Insulation for High Voltage Cables

   Author : Yingwei Ouyang; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; insulation; polypropylene; blends; thermoplastic; high voltage; polymer;

   Abstract : High voltage direct current (HVDC) cables that seamlessly integrate renewables have an important contribution to the modern world’s efforts towards a more sustainable future. Extruded HVDC cables that efficiently and reliably transport electricity require robust insulation materials with good thermomechanical and dielectric properties. READ MORE

6. 4. On processing of thermoplastic starch

   Author : Mats Thunwall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylose; starch; extrusion; thermoplastic starch;

   Abstract : Starch is a biodegradable material produced in many different crop plants. Since it is biodegradable, inexpensive, generally has good barrier properties and comes from a renewable source it would be an ideal material to use in e.g. packaging applications. READ MORE

7. 5. Novel Thermoplastic Material Concepts for High Voltage Cable Insulation - Engineering Immiscible Blends for a Sustainable Future

   Author : Yingwei Ouyang; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polypropylene; polymer blends; thermoplastic; copolymer; high-voltage power cable insulation; polyethylene;

   Abstract : To cope with our growing demand for energy in a sustainable way, efficient long-distance power transmission via high voltage direct current (HVDC) cables is crucial – these cables facilitate the integration of renewable energy into our power networks. For reliable and efficient power transmission, underground and undersea cables require robust insulation materials that possess a high level of mechanical integrity, a low direct-current (DC) electrical conductivity and a high thermal conductivity at the elevated temperatures experienced during cable operation.
