masterbatches to plastics can provide a num-
ber of benefits, including increased stiffness,
improved dimensional stability, enhanced trans-
parency, and faster processing times. They are
commonly used in the production of products
such as injection-molded parts, films, and fibers.
Nucleating additive masterbatches are typically
added to plastics during the compounding pro-
cess, which involves melting the plastic resin and
mixing it with the additives. The resulting mixture
