VLC Series Products

Our liquid colorant systems are not just compatible with the base polymer, but frequently improve the process and/or performance properties of the plastic part.

The VLC Series products have been formulated to deliver high pigment loadings at low letdown ratios, which allow the end user to produce more uniform and consistent parts. We achieve these results by custom designing each liquid colorant system to your polymer and process, leading to significantly lower overall cost. The VLC Series line can also be custom formulated to meet "Toxic in Packaging Laws" (formerly "CONEG"), FDA, NSF, and RoHS compliance requirements.

Most commercially available polymers contain sufficient amounts of a stabilization package to protect them, but there are cases where additional protection maybe required. If you're trying to improve durability, processing at a higher temperature, or reprocessing the polymer, we can incorporate the correct stabilization package into our liquid colorants to meet your needs.

Ultraviolet Light Stabilizers

Stabilization of the polymer is critical if your plastic part is going to be exposed to sunlight, and there are two types of UV Light Stabilizers available to protect the polymer:

Hindered Amine Light Stabilizers (HALS) are extremely efficient stabilizers that do not absorb UV radiation, but act to inhibit degradation of the polymer, thus extending its durability. Significant levels of stabilization are achieved at relatively low concentrations.

UV Absorbers (UVA) have the property to convert the energy absorbed from UV light into heat, this heat then dissipates through the substrate. UV absorbers will remain active during the life-time of the plastic part.

Ultraviolet Light Stabilizers can also be incorporated into our liquid colorants to meet your requirements.
