Abstract

The present disclosure provides a pellet. In an embodiment, the pellet includes a body having a first end and an opposing second end. The body is composed of a polymeric material. The body has a length and a diameter (body diameter). A channel having a diameter (channel diameter), extends through the body from the first end to the second end. The pellet has a channel diameter-to-body diameter ratio from 0.05 to 0.45. The present disclosure also provides a process for soaking the pellet in a liquid additive and forming a loaded pellet with the additive in the pellet body.
