Liquid masterbatches

Liquid masterbatches is plastic colorants in which pigments and additives are dispersed in a liquid dispersion medium. Because it is liquid, it has good distribution properties (even coloring can be achieved) even at low additive amounts of 1% or less, and is excellent for coloring light colors and transparent colors, contributing to cost reduction, inventory reduction, and retention of physical properties.
TOYOCOLOR offers liquid masterbatches in a wide variety of colors that meet the standards of the Polyolefin Hygiene Council (POPL: PET resin) and the U.S. Food and Drug Administration (FDA).

Target resin		PET, PET-G, PC, etc.
Addition amount (ratio to resin)		～1.0％
Recommended molding method		Extrusion molding, injection molding, etc.

Features of our products

Feature 1: No shot variation or color unevenness, stable quality

Even with an addition amount of 1/20 of that of a solid masterbatches, stable coloring is achieved with no variation or color unevenness.

Comparison of shot-to-shot variation and color unevenness of injection molded plates (5 shots)

Feature 2: Can be colored evenly even at low additive amounts and maintains mechanical properties.

Since it can be colored with a lower additive amount than solid masterbatches, mechanical properties are also maintained.
