    • Moulded polypropylene foams produced using chemical or physical blowing agents: structure–properties relationship 

      Saiz-Arroyo, Cristina; Saja, José Antonio de; Velasco Perero, José Ignacio; Rodríguez-Pérez, Miguel Ángel (2012)
      Article
      Accés restringit per política de l'editorial
      Polypropylene (PP) foams have become essential items due to their excellent properties. Nevertheless, obtaining net-shaped PP foams with medium relative densities is a complicated issue. In this article, two processes ...

    • Optical expandometry: a technique to analyze the expansion kinetics of chemically blown thermoplastic foams 

      Solórzano Quijano, Eusebio; Antunes, Marcelo de Sousa Pais; Saiz-Arroyo, Cristina; Rodríguez-Pérez, Miguel Ángel; Velasco Perero, José Ignacio; Saja, José Antonio de (2012-07)
      Article
      Accés restringit per política de l'editorial
      A novel technique to determine in situ the free expansion kinetics of chemically foamed thermoplastic foams, so-called optical expandometry, is presented in this work. This technique is based on the camera monitoring ...

    • Polypropylene/Clay Nanocomposites: Combined effects of clay treatment and compatibilizer polymers on the structure and properties 

      Velasco Perero, José Ignacio; Ardanuy Raso, Mònica; Redondo Realinho, Vera Cristina de; Antunes, Marcelo de Sousa Pais; Fernández Renna, Ana Inés; González-Peña, J.I.; Rodríguez-Pérez, Miguel Ángel; Saja, José Antonio de (Wiley, 2006)
      Article
      Accés restringit per política de l'editorial
      Combined effects of clay treatment and compatibilizer polymers on the structure and properties of polypropylene/clay nanocomposites were studied. Dynamic mechanical analysis was used to analyze comparatively the dynamic ...

    • The effect of anionic clay particles on the structure and thermomechanical behavior of sodium partially-neutralized EMAA ionomer 

      Ardanuy Raso, Mònica; Velasco Perero, José Ignacio; Rodríguez-Pérez, Miguel Ángel; Saja, José Antonio de (2010-06-20)
      Article
      Accés obert
      Nanocomposites based on a sodium partially-neutralized ionomer of poly (ethylene-comethacrylic acid) (EMAA) and MgAl layered double hydroxide (LDH) particles with and without organic modification were prepared from a melt ...

    • Thermal conductivity anisotropy in polypropylene foams prepared by supercritical CO2 dissolution 

      Antunes, Marcelo de Sousa Pais; Redondo Realinho, Vera Cristina de; Velasco Perero, José Ignacio; Solórzano Quijano, Eusebio; Rodríguez-Pérez, Miguel Ángel; Saja, José Antonio de (2012-09)
      Article
      Accés restringit per política de l'editorial
      Different relative density polypropylene foams were prepared by means of two foaming processes: chemical foaming by compression moulding and physical foaming by high pressure CO2 dissolution. By controlling the foaming ...

    • Thermal Conductivity of Carbon Nanofibre-Polypropylene Composite Foams 

      Antunes, Marcelo de Sousa Pais; Redondo Realinho, Vera Cristina de; Solórzano Quijano, Eusebio; Rodríguez-Pérez, Miguel Ángel; Saja, José Antonio de; Velasco Perero, José Ignacio (Trans Tech Publications, 2010)
      Article
      Accés restringit per política de l'editorial
      Carbon nanofibre-reinforced polypropylene nanocomposites containing from 5 to 20 wt.% of carbon nanofibres and a chemical blowing agent were melt-compounded and later foamed using compression-moulding. Alongside their ...
