    • Effects of UV radiation on the charge trapping capability of PET 

      Cañadas Lorenzo, Juan Carlos; Diego Vives, José Antonio; Mudarra López, Miguel; Parsa, Seyedeh Elaheh; Sellarès González, Jordi (Institute of Physics (IOP), 2019-02-06)
      Article
      Open Access
      Poly(ethylene terephthalate) (PET) is able to retain space charge in traps, as is usual in dielectric materials. This allows the material to attain an almost permanent polarization when space charge is displaced by an ...

      Open Access
      El objetivo de este proyecto ha sido la preparación y caracterización térmica, mecánica y a fractura de mezclas de Poli(Etilén tereftalato) reciclado (R-PET) con un 10 % en peso de dos tipos de Polietilenos (alta (HDPE) ...
    • Heat transfer in shrink films 

      El Marrasse Zarioui, Salma (Universitat Politècnica de Catalunya, 2015-01)
      Bachelor thesis
      Restricted access - author's decision
      Polyethylene is a thermoplastic polymer composed of a repeating unit (-CH2-CH2)n. It is the most consumed plastic due to its low price and ease of manufacture. It can be described by three basic characteristics that influence ...
    • Influence of foaming process on the structure-properties relationship of foamed LDPE/silica nanocomposites 

      Saiz Arroyo, Cristina; Rodríguez Pérez, Miguel Ángel; Velasco Perero, José Ignacio; Saja, José Antonio de (Elsevier, 2013-05)
      Article
      Restricted access - publisher's policy
      In this paper LDPE/silica nanocomposites are foamed by two different processes. First one is the pressure quench method which is based on the use of a physical blowing agent and second one is the improved compression ...
