Polymer Compounding for Developing Advanced Materials

Compounding of polymers comprises the influences of the polymers, additives, and fillers on the morphology developed based on the rheology of the melts, together with mechanisms involved during the melt mixing process. Development of morphology in the polymer system is very crucial to establish the desire physical properties. A team at IIT Delhi is developing novel polymer compounds with specific properties relevant to their intended subsequent applications. Most compounding is done on twin-screw extruders with co-rotating screw profile with various diameters and L/D as well as mixing elements. Polymer nanocomposites are the one of the potential area of research for the development of polymer compounds with multifunctional properties. Dispersion and distribution of another polymer, micro and nano fillers are considered to be key step and can be achieved by various compounding techniques.
Polymer blends   Polymer Composites   Polymer Nanocomposites
Thermoplastics + Elastomers   Thermoplastics + Fillers   Thermoplastics + Nanoclay
Thermoplastics + Engineering plastics   Thermoplastics + Short Fibers   Thermoplastics + Nanotubes
Thermoplastics + Biopolymers   (Glass fiber, Natural fibers)   Polymer blends + Nano fillers
Thermoplastics + Special polymers   Thermoplastics + Long Fibers    
The aforesaid materials were developed with high strength, toughness along with other value added properties either to replace the metal based components or for better processability or to cater special application demand.
