What Limits the Color You Can Achieve on a Recycled Resin?

The final color on recycled resin is limited by the resin's base tone, its lot-to-lot variation and what it carries inside.

¿Por qué el color falla más fácil en película delgada que en piezas gruesas?

Technical21 Sep 2026 8 min

Why Does Color Fail More Easily in Thin Film Than in Thick Parts?

In a film a few microns thick, the pigment has less path to cover and any dispersion defect is exposed.

¿Tu planta necesita el mismo soporte técnico que una transformadora grande?

Technical14 Sep 2026 8 min

Does Your Plant Need the Same Technical Support as a Large Processor?

You need more. A plant without its own laboratory depends on its masterbatch supplier's laboratory to validate color, dispersion, and performance.

¿Cuándo conviene pedir una visita técnica antes de aprobar un desarrollo de color?

Technical14 Sep 2026 8 min

When Is It Worth Requesting a Technical Visit Before Approving a Color Development?

Request it when the color depends on variables the laboratory cannot reproduce: your machine, your mold, your resin, and your thermal profile.

¿Qué debes revisar antes de cambiar de proveedor de masterbatch?

Technical08 Sep 2026 7 min

What Should You Check Before Switching Masterbatch Suppliers?

Before switching masterbatch suppliers, review technical support, traceability, and batch repeatability, not just the price per kilogram.

Technical08 Sep 2026 7 min

Can You Reduce Masterbatch Consumption Without Losing Color Coverage?

You can cut masterbatch consumption without losing coverage, as long as the change is validated with dispersion tests and a dosing curve before production.

¿Qué diferencia hay entre cumplir FDA y cumplir Cofepris en un masterbatch?

Regulatory01 Sep 2026 7 min

What's the Difference Between FDA and Cofepris Compliance for a Masterbatch?

FDA compliance certifies the additive in the United States. Cofepris demands extra documentation and traceability. A masterbatch can meet one and not the other.

¿Por qué producir volumen sin validar una muestra puede salir más caro?

Technical01 Sep 2026 7 min

Why Can Producing Volume Without Validating a Sample Cost You More?

Skipping sample validation spreads any formulation error across the whole order. Reprocessing a batch costs far more than the time the shortcut saves.

¿Qué documentación debe acompañar cada pedido de masterbatch?

Regulatory25 Ago 2026 7 min

Technical18 Ago 2026 6 min

Why Does a Color Look Correct in the Plant but Different at the Point of Sale?

Two colors can look identical in the plant light booth and different at the point of sale. That is metamerism, and one light source will not catch it.

¿Por qué un color aprobado a simple vista puede rechazarse en control de calidad?

Technical18 Ago 2026 6 min

Why Can a Color Approved by Eye Get Rejected in Quality Control?

The eye judges color inconsistently; a spectrophotometer measures it with Delta E. That is why a color approved by eye gets rejected in the lab.

¿Por qué dos colores se contaminan entre sí en una pieza coextruida?

Technical11 Ago 2026 5 min

Why Do Two Colors Contaminate Each Other in a Co-Extruded Part?

Color contamination in co-extrusion happens at the interface of the two flows: pigment migration, poor dispersion, or a viscosity mismatch.

¿Por qué aparecen burbujas en piezas de Nylon con fibra de vidrio?

Technical11 Ago 2026 5 min

Why Do Bubbles Appear in Nylon Parts with Fiberglass?

Bubbles in Nylon parts with fiberglass almost always come from residual moisture in the resin, not from the masterbatch: Nylon is a hygroscopic material.

¿Qué es el índice de fluidez de tu resina y por qué puede arruinar el llenado del molde?

Technical04 Ago 2026 6 min

What Is Your Resin's Melt Flow Index and Why Can It Ruin Mold Filling?

¿Cuánto tiempo puede estar el masterbatch dentro del cañón antes de degradarse?

Technical04 Ago 2026 6 min

How Long Can Masterbatch Stay Inside the Barrel Before It Degrades?

If material stays too long in a hot barrel it burns, streaks, or turns brittle, and the defect gets mistaken for a pigment problem. Residence time matters.

¿Por qué el color de tu pieza mancha todo lo que toca?

Technical28 Jul 2026 7 min

Why Does the Color of Your Part Stain Everything It Touches?

Color stains when pigment migrates to the surface. The causes: masterbatch overdosing, incompatibility with the resin, and poor dispersion.

¿Por qué aparecen puntos de otro color justo después de cambiar de lote?

Technical28 Jul 2026 6 min

Why Do Specks of Another Color Appear Right After a Batch Change?

Specks of another color after a batch change are cross contamination: remnants of the previous color in the barrel, screw, or mold. Purge and clean.
