Black Desiccant Masterbatch for Use in Trash Bag Film and Injection Molded Plastic Components
Overview
This black desiccant masterbatch serves a dual function: it provides consistent black coloration while effectively absorbing moisture during plastic processing. It is engineered for application in recycled LLDPE, LDPE, HDPE, and PP materials, supporting the production of high-performance and environmentally sustainable plastic products.
Recommended Usage Proportion
A loading ratio of 1–5% is generally advised, though this may be modified depending on the moisture level present in the recycled resin.
