Name: Colorex Odor Eliminating Masterbatch
Brand: Colorex

What is Odor-Removing Masterbatch?

One of the greatest challenges in achieving sustainability and circular economy goals in the plastics industry is the unwanted odours emerging in recycled polymers (PCR/PIR). Our odour absorber masterbatch series, developed in Colorex R&D laboratories, offers a solution to this problem beyond traditional masking methods with advanced chemical neutralization technology. Our special formulations chemically trap and neutralize volatile organic compounds (VOCs) and sulfur, amine, or aldehyde-based molecules that cause odour within the polymer matrix during the recycling process.

Thanks to this innovative technology, which allows you to increase your recycled plastic usage rate especially in automotive interior trim parts, indoor packaging, and white goods production, we guarantee an odourless, fresh, and high-quality consumer experience in your final products.

Recommended Dosage

In recycled (PCR/PIR) polymers with light odour: 0.5% - 1.0%
In recycled materials with medium and intense odour: 1.5% - 2.5%
In automotive interior trim and critical parts with high odour sensitivity: 2.0% - 3.0%

Applications and Effects on the Final Product

Applications / Application Areas

Post-consumer (PCR) and post-industrial (PIR) recycled pellets
Garbage bags, pipes and crates produced from recycled raw material
Automotive interior cabin plastics (parts requiring a low-odor standard)
Household goods, storage containers, cleaning equipment and shoes/slippers
Engineering plastics processed at high temperatures and rubber/TPE compounds

Affected Properties / Effects on the Final Product

Volatile Organic Compound (VOC) absorption: Permanently eliminates the amine, aldehyde, ketone and fatty acid gases that cause bad odor by trapping them in its molecular pores.
Sensory quality and consumer perception: Neutralizes the burnt, sour or waste odor of recycled plastic, bringing it closer to the virgin raw material standard.
Gas-induced micro-voids: Because it traps volatile gases within the polymer, it supports surface smoothness.
Preservation of mechanical properties: Because it does not mask with perfume and does not cause chemical degradation, it does not impair the impact/tensile strength of the product.
Color neutrality: Does not affect the base color of the product and is used safely in transparent and colored applications.

Effect on the Process and Production Line

Noticeably reduces the heavy smoke at the extruder die exit and the unpleasant odor in the working environment inside the factory.
Reduces gas bubble formation on pelletizing and blown film lines.
