Colors and custom compounds
There are several factors that can impact color, including the type of resin used, additives, texture and shape. Visual perception is another factor to consider.
Compounding: An introduction
Compounding of plastic is a process that includes melt-blending of plastics with specific additives that are used to change the thermal, physical, aesthetic and electrical characteristics of the material.
Plastics compounding involves an intricate process with multiple stages. These may include determining additives ratio, high-speed mixing via twin-screw extruders, melt mixing, and cooling, all before final pellet cutting and packaging. A range of materials can be used. Those materials include polypropylene, polyethylene, polyvinyl chloride, polystyrene and expanded polystyrene, polyethylene terephthalate, polyurethane, acrylonitrile butadiene styrene (ABS), nylon and other polymers.

Compounding: Glass and other fillers
Glass remains the most common additive in resins for many injection molding shops. Glass fibers can offer significantly more strength and rigidity when compared to the performance of unfilled resins.
In the laboratory: Compounding solutions
Plastics compounding remains one of the best ways to tailor a material to an application, and the laboratory often is where some of the toughest challenges are solved.
Recycling content: Resins going ‘green’
With so much emphasis placed on green options, plastics processors can take steps to decrease their ecological footprint with compounds that include recycled content.
