Cold processes, such as shredding and crumbing, are recommended to prevent the degradation in the hot processes, such as
pelletization.
He was an expert on its effects on the reinforcing properties of tire treadwear and rubber, and also on its
pelletization during the manufacturing process.
However, once the wood is dried (to ~6.5% MC) and densified through the
pelletization process, the energy content per unit volume nearly doubles and allows for more economical transportation, handling, and combustion in automated appliances (USDA 2009).
Compounding lines that utilize single-screw extruders as the pumping device for
pelletization can be severely rate limited if the metering channel of the single-screw machine is not optimized for the process.
The objectives of this handbook are to present a comprehensive, balanced treatment of the various types of equipment commercially available and to describe what happens to a polymer as it passes through the equipment from feed to
pelletization.

The significant difference in molecular weight (MW) is likely due to the additional thermal processing step required for
pelletization. During foaming, powdered PHBV and pellet PHBV were blended at a composition of 10/90 by weight because the presence of powdered PHBV appeared to prevent the retention of the powdered blowing agent in the mixing container.
