Customer Success Story: Kenyan Drum Manufacturer Upgrades Product Quality with NUOXIN High-Gloss Black Masterbatch

A plastics processor from Kenya recently shared positive feedback after switching to our High-Gloss Black Masterbatch Series for HDPE and recycled-material drum production. The customer runs a large manufacturing line for 20L–120L plastic drums used in chemicals, agriculture, and daily storage. Their main challenge was simple but common across the African market: recycled pellets looked dull, uneven, and lacked a clean black finish.

Challenge: Recycled Material with Poor Color Performance

The factory relies heavily on locally sourced recycled resin. Although cost-effective, the material often comes with many color variations. Some batches appear gray, others turn brown after extrusion. Even after adding low-concentration black additives, the final drums still looked faded and lacked surface gloss. The appearance did not match the quality level the brand wanted.

The customer needed a strong tinting option with stable dispersion — something powerful enough to cover recycled resin color variation and still keep the processing smooth

Solution: NUOXIN High-Gloss Black Masterbatch (35%–45% Carbon Black)

After discussing production needs, we recommended our High-Gloss Series Black Master Batch, made with:

• 35%–45% high-jet carbon black

• Clean dispersion technology

• PP/PE carrier for strong compatibility

• High tinting strength for recycled resin

This grade is specifically designed for drums, bins, and blow-molded containers that require deep color and improved visual appeal.

Results: Deep Black Color, Strong Gloss, and Better Overall Appearance

Within the first production trial, the customer noticed a clear improvement:

• The drums came out deep black, with no gray or brown patches.

• The surface showed higher gloss, giving the finished products a premium look.

• The color stayed stable during long runs, even when using 100% recycled HDPE.

• No filter blockage or processing instability was reported.

According to the customer:

“Your black masterbatch gives our recycled drums a clean and glossy finish. They look high-quality now, and our buyers immediately noticed the difference.”

Why It Worked

Our high-gloss formula contains a higher carbon black concentration than many standard products on the market. This allows the masterbatch to easily mask impurities and uneven tones in recycled resin. Strong dispersion means the color spreads evenly, and UV resistance helps the drum maintain its appearance outdoors.

For manufacturers in Africa, where sunlight is strong and recycled material is widely used, this balance of coverage and brightness creates a competitive advantage.

Long-Term Cooperation Ahead

With the success of the first batch, the customer has already placed repeat orders of the same grade for long-term drum production. We will continue to offer technical support and help them adjust formulas in future projects.

NUOXIN remains committed to supporting African processors with reliable black masterbatch solutions that meet both performance and cost expectations.
