Thermoplastic polymers constitute approximately 75 percent of the plastics market and are widely utilized for their excellent strength-to-weight ratio, high processability, corrosion resistance, and affordability. The properties of these polymers can be further enhanced by incorporating additives such as fibers or nanoparticles. Alternatively, thermoplastic polymers can act as a supporting matrix for various function-bearing particles. Most thermoplastics are currently derived from non-renewable fossil resources and are largely non-biodegradable. However, the development of nature-derived, recyclable, and biodegradable polymeric materials, such as polylactide (PLA) and bionylon-56 (PA56), is gaining traction, finding sustainable applications in industries like automotive and electronics. The development of novel thermoplastic polymers and their composites typically requires extensive testing, involving compounding and subsequent specimen characterization. Plastic compounding is a complex process that involves melt-blending plastics with specific additives to alter various material characteristics, such as thermal and physical properties. This intricate process can include stages like determining additive ratios, highspeed mixing, melt mixing using twin-screw extruders, cooling, and finally pellet cutting. The pellets is the most common form that thermoplastic polymers, either virgin or compounded, are sold and passed downstream the processing workflow to steps such as injection molding, hot-pressing, or 3D printing.
