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

Technical08 Sep 2026 7 min

What Should You Check Before Switching Masterbatch Suppliers?

Switching masterbatch suppliers means reviewing technical support, traceability documentation, and batch-to-batch repeatability, not just the price per kilogram. Validating these fronts before you decide prevents production rejections and protects the relationship with your client.

¿Se puede reducir el consumo de masterbatch sin perder cobertura de color?

Technical08 Sep 2026 7 min

Can You Reduce Masterbatch Consumption Without Losing Color Coverage?

You can reduce masterbatch consumption without losing color coverage, as long as the adjustment is validated with dispersion tests and a dosing curve before you change the formula on your plant floor.

¿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?

Meeting FDA requirements certifies the additive under the U.S. regulatory framework. Meeting Cofepris requirements demands additional documentation and traceability to sell in Mexico. A masterbatch can meet one without automatically meeting 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 amplifies any formulation error across the entire order volume. The cost of reprocessing or scrapping a full batch far outweighs the time saved by skipping that upfront validation.

¿Qué documentación debe acompañar cada pedido de masterbatch?

Regulatory25 Aug 2026 7 min

What Documentation Should Accompany Every Masterbatch Order?

A masterbatch batch without a quality certificate, technical data sheet, or safety data sheet stops your line and complicates any traceability audit. Here is the documentation that should accompany every order.

¿Qué exige un masterbatch para piezas plásticas de contacto infantil?

Regulatory25 Aug 2026 7 min

What Does a Masterbatch for Child-Contact Plastic Parts Require?

A masterbatch for child-contact plastic parts must meet heavy metal migration limits and carry certification specific to that use, different from food-contact certification. Here is how to validate it before approving the batch.

¿Por qué un color se ve correcto en planta pero distinto en el punto de venta?

Technical18 Aug 2026 6 min

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

Two colors can look identical under the plant's light booth and different under the point of sale's lighting. That is metamerism, and validating under a single light source won't catch it.

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

Technical18 Aug 2026 6 min

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

The human eye judges color inconsistently; a spectrophotometer measures it with Delta E, an objective number. That gap is why a color approved by eye can still get 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 a co-extruded part happens at the interface where the two material flows meet, caused by 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?

The melt flow index (MFI) measures how fast your resin moves through the equipment. When it isn't right for your process, no masterbatch adjustment can fully fix an incomplete mold fill.

¿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?

Temperature and residence time in the machine are variables that are often underestimated. When material stays too long inside a hot barrel, it can burn, streak, or become brittle, and the defect is easily mistaken for a pigment problem.

¿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?

A part color stains when the pigment migrates to the surface instead of staying dispersed inside the plastic. The most common causes are masterbatch overdosing, incompatibility between pigment and resin, and poor dispersion during processing.

¿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 left in the barrel, the screw or the mold that get carried into the new run. They are solved with proper purging and cleaning between colors.

¿Cuánto masterbatch blanco necesitas para cubrir una resina reciclada obscura?

Technical21 Jul 2026 7 min

How Much White Masterbatch Do You Need to Cover a Dark Recycled Resin?

There is no single dosage. The amount of white masterbatch depends on the base tone of the recycled resin, part thickness, the type of titanium dioxide and the process. It is determined by validating a sample before producing.

¿Qué necesitas confirmar antes de pedir un masterbatch con efecto metálico o perlado?

Technical21 Jul 2026 7 min

What Do You Need to Confirm Before Ordering a Metallic or Pearlescent Masterbatch?

Before ordering it you must confirm the real geometry of the part, the process and gate location, the base resin, the particle size of the effect and validation on a real part, not on a flat plaque.

¿Se Puede Usar Masterbatch Tradicional en Resinas Biodegradables?

Technical7 Jul 2026 6 min

Can Traditional Masterbatch Be Used with Biodegradable Resins?

The technical answer depends on three variables: the type of biodegradable resin, the processing temperature, and whether the application requires compostability certification. In some cases conventional masterbatch can be processed with biodegradable resins. In others, a masterbatch with a compatible carrier is required.
