Twin screw mini-extruder

The freeze-diy RSF was milled by a food processor and kept into a dessicator. The RSF/ PP nanocomposite was made by blending PP pellets with 1 6% MAPP (ratio of PP weight, wt%) and 2 11% RSF (ratio of total weight, wt%). All materials were then fed into a Haake Mini-Lab twin-screw extruder (Thermo Electron Corp., Hamburg, Germany). The blends were processed for 10 min, 20 min, 30 min at 50 rpan and 180 °C, 190 °C and 200 °C using a... 

Intercalated PET montmorillonite clay nanocomposites were compounded via melt-blending in a corotating mini twin-screw extruder. Nanocomposites compounded with l,2-dimethyl-3-N-hexadecyl imidazolium treated montmorillonite showed higher levels of dispersion and delamination than those with a typical quaternary aimnonium salt (39). 

An amorphous polyester-montmorillonite nanocomposite prepared from condensation of 2,2,4,4-tetramethyl-l,3-cyclobutanediol, 1,3-propanediol, and dimethylterephthalate produced unexpected mechanical properties [45]. Cloisite 20A was melt blended with the polymer at 2.5,5, and 10 wt.% with a Haake HBI System 90 drive attached to a Rheomex CTW 100 twin-screw extruder. The r/min of the extruder was 60 and the temperature was 120°C. The test samples were prepared in two different injection molders. The test samples from the polyester-montmorillonite composite at 5% Cloisite 20A content were prepared with a Demag Ergotech 35 at 150°C with a pressure range of 10000 to 11000 psi. The test samples from the polyester-montmorillonite composites with 2.5, 5.0, and 10% Cloisite 20A content were prepared with a mini-jector molding machine at a temperature range of 190-200°C. 

Silica aerogel-poly(ethylene-co-vinyl acetate) composite blends were prepared by Allan et al. [117]. Normally, these types of polymers are used for solar coverings including photovoltaic modules and commercial greenhouse films. Here, the silica aerogels were melt-mixed using a mini twin-screw extruder with EVA pellets in order to form S A/EVA composite, which were pressed into thin films with controlled thickness.
