  1. 1. Analysing and concluding the cost/performance matrix for biopolymer blends with different renewable contents

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Linda Ehrenberg; Filip Nilsson; [2018]
    Nyckelord :biopolymers; polymer blends; PHA; PBS; PLA; PP; compounding; blends; cost; price estimations; renewable content; feedstock; polymer technology; polymerteknologi; Technology and Engineering;

    Sammanfattning : Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. LÄS MER

  3. 2. Från plagg till plagg

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Emma Jemt Gardell; Hannah Racklin; [2016]
    Nyckelord :Polyamide 6.6; PA6.6; spandex; mechanical recycling; melt spinning; injection moulding; Polyamid 6.6; PA6.6; elastan; termomekanisk återvinning; smältspinning; formsprutning;

    Sammanfattning : De senaste decennierna har visat på en stor ökning av den textila konsumtionen som följd av efterfrågan, samtidigt som den textila återvinningen idag är nästintill obefintlig. Detta leder till att mycket av det textila materialet deponeras istället för att återvinnas, vilket innebär ett stort slöseri av redan befintlig råvara som skulle kunna användas till att skapa nytt textilt material.

  4. 3. Phthalate replacement by fast fusing non-phthalate plasticizer

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Ibert Tommie; [2016]
    Nyckelord :Non-phthalate; PVC; Plasticiser; Phthalates; Oil; Fusion; Gelation; Phthalate free;

    Sammanfattning : A key trend in the PVC market is to replace or decrease the amount of phthalate plasticisers used due to increasing health concerns. Therefore, the demand for non-phthalate based plasticisers is growing rapidly. LÄS MER

  5. 4. Industrial energy efficiciency drivers and barriers, and global sustainability: A case study of a polymer compounding company

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Mile Misic; [2016]
    Nyckelord :polymer compounding; business strategy; sustainable development goals; drivers and barriers; energy efficiency; Earth and Environmental Sciences;

    Sammanfattning : This master thesis was written in a time when major changes in global sustainability and climate architecture were happening. Aim of this thesis is to look into how a single manufacturing company can, through enhanced energy efficiency, contribute to global sustainability in multiple ways. LÄS MER

  7. 5. Investigation of the dielectric breakdown strength of polymer nanocomposites

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Mattias Karlsson; [2014]
    Nyckelord :breakdown; polyethylene;

    Sammanfattning : The aim of this thesis is to investigate the possibility of enhancing the dielectric breakdown strength (DBS) of low density polyethylene (LDPE) with addition of voltage stabilizing additives. In the first part of the thesis, the influence of various process parameters on the alternating current DBS of pure LDPE and LDPE containing either 3 or 30 wt% magnesium oxide nanoparticles was investigated.
