White Masterbatch Explained: Whiteness, Opacity, Dispersion and Appearance
A White Masterbatch is a concentrated dispersion of Titanium Dioxide in a polyolefin carrier, added to a base resin to deliver whiteness and opacity in the finished part. Four variables jointly move the outcome — TiO₂ loading, dispersion, carrier match to…
ReadDesiccant Masterbatch Explained: Moisture, Bubbles, Recycled PE, Dosage and Storage
A Desiccant Masterbatch is a concentrated dispersion of Calcium Oxide in a polyolefin carrier, added to a base resin to consume residual water inside the melt. Once mixed into the melt at extrusion or injection temperature, the CaO reacts with residual…
ReadWhite Masterbatch vs Desiccant Masterbatch: Which One Do You Actually Need?
White Masterbatch and Desiccant Masterbatch are both concentrated polyolefin-carried masterbatches, and they end up next to each other in the catalog for supply-chain reasons — same carriers, same processing equipment, same suppliers. That is where the…
ReadDesiccant Masterbatch Dosing — When It Fixes Bubbles and When It Hides a Drying Problem
A desiccant masterbatch converts trace moisture in the melt into calcium hydroxide so the water never becomes vapour in the die. It is a genuine fix for the residual moisture carried by recycled polyolefins and mineral fillers. It is not a substitute for…
ReadWhich Masterbatch Solves the Problem I Actually Have? White vs Desiccant — The Diagnostic Hub
White Masterbatch and Desiccant Masterbatch sit next to each other in most masterbatch catalogs, but they solve fundamentally different engineering problems. White Masterbatch — a Titanium Dioxide-based system carried in a compatible polyolefin — addresses…
