When it comes to plastic manufacturing, Colour Masterbatch plays a pivotal role in delivering vibrant and consistent results. However, even small mistakes in handling, formulation, or application can lead to costly defects, reduced performance, or dissatisfied customers. At Kothari Polymers, we believe knowledge is the first step to efficiency. In this post, we’ll explore the top mistakes commonly made with Colour Masterbatch—and how you can avoid them.
6 Common Colour Masterbatch Mistakes and Smart Ways to Prevent Them
Incorrect Masterbatch Dosage
Mistake: Overdosing or underdosing Colour Masterbatch leads to inconsistent shades, unnecessary material waste, and higher costs.
How to Avoid It:
Always follow the recommended let-down ratio provided by your supplier. At Kothari Polymers, our Colour Masterbatch comes with precise guidelines to ensure consistent results and cost-effective usage.
Incompatible Carrier Resin
Mistake: Using a masterbatch with an incompatible carrier resin can result in poor dispersion, reduced mechanical properties, or processing issues.
How to Avoid It:
Ensure the carrier resin of the masterbatch is compatible with your base polymer. At Kothari Polymers, we offer custom solutions tailored to your resin type, whether it’s PE, PP, PET, or others.
Poor Dispersion of Pigments
Mistake: Improper mixing or using low-quality masterbatch results in streaks, spots, or uneven coloration in the final product.
How to Avoid It:
Use high-quality masterbatches with excellent dispersion characteristics. Kothari Polymers employs advanced twin-screw extrusion technology to guarantee superior pigment dispersion.
Ignoring Processing Temperature Guidelines
Mistake: Exposing Colour Masterbatch to temperatures beyond its tolerance range can degrade pigments and affect color accuracy.
How to Avoid It:
Monitor processing temperatures closely during extrusion or molding. Refer to technical datasheets for optimal temperature ranges, which we provide with every Kothari Polymers masterbatch.
Using the Wrong Shade or Pigment Type
Mistake: Selecting the wrong color shade or non-lightfast pigments can lead to product rejection or fading over time.
How to Avoid It:
Work closely with your masterbatch supplier during shade development. At Kothari Polymers, we offer shade matching and testing to ensure long-lasting, UV-stable results that meet your branding and performance needs.
Skipping Pre-Testing or Trials
Mistake: Launching production without pre-testing the masterbatch can lead to production delays, rework, or customer complaints.
How to Avoid It:
Conduct small-scale trials to verify performance before full-scale production. Our team at Kothari Polymers assists with sampling and technical support to fine-tune your application before going live.
