  1. 1. Aging and heat-sealing properties of films based on wheat gluten

    Författare :Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

    Sammanfattning : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. LÄS MER

  3. 2. The Ageing of Fuel Lines Based on Polyamide-12

    Författare :Kai J. Kallio; Mikael Hedenqvist; Mikael Rigdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipes; ethanol; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Today, the use of bio-fuels for cars is increasing. There is a wide range of biofuelsavailable world wide, in Sweden ethanol containing fuels are favoured.For car manufacturers there is a need to be able to predict short and long termproperties of fuel lines subjected to ethanol containing fuels to ensure properlong term behaviour.

  4. 3. Protein-Based Adhesives for Particleboards

    Författare :Sara Khosravi; Mats K. G. Johansson; Mikael Hedenqvist; Mikael Gällstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

    Sammanfattning : The main objective of this study was to elucidate the possibilities to use wheat gluten (WG) as a binder for particleboards, as well as soy protein isolate (SPI). The focus was on the effect of the adhesive formulation and the processing conditions, while the press parameters were kept constant. LÄS MER

  5. 4. Interactions between polymers and the environment

    Författare :Nazanin Alipour; Mikael S. Hedenqvist; Antal Boldizar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deltamethrin; piperonyl butoxide; polyethylene; migration; multilayer film; EVOH; n-hexane; crystallization; mechanical properties; X-ray scattering; swelling; larvae; protein; lipid; moisture sorption; release; nanoclay; polypropylene; degradation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : This dissertation addresses the structure and properties of a number of polymer-based materials when they come into contact with specific environments. The first part describes the migration and depletion of active substances from insecticide-impregnated polyethylene sheets in water and air at different humidity levels and higher temperatures.
