Sodium Sulfate Filler Masterbatch Gains Popularity in Kenya
While many factories slowed down during China’s National Day holiday, our production and shipping teams stayed active to meet overseas demand. One highlight this season is the increasing popularity of our sodium sulfate filler masterbatch in the Kenyan market. Orders kept flowing, and containers continued to depart from the port without interruption.
Stable Supply During Holiday Period
National Day is one of the longest public holidays in China, but our logistics team made detailed planning weeks in advance. We maintained regular production schedules, arranged overtime shifts, and coordinated with freight forwarders to ensure smooth shipment to African destinations. Thanks to this preparation, several batches of sodium sulfate masterbatch were successfully shipped to Nairobi, Mombasa, and other industrial hubs.
Kenyan customers appreciate the stability of our supply chain. Our buyer, Peter, said, "Thank you very much for your on-time delivery during the Chinese holiday. You are a responsible supplier for your customers."
Why Sodium Sulfate Filler Masterbatch Is Gaining Popularity
Kenya’s plastic converting sector continues to expand, especially in packaging film, injection molding, and blow molding. Filler masterbatch is widely used to reduce production costs and improve stiffness in PE and PP products. Compared with calcium carbonate filler, sodium sulfate filler masterbatch offers smoother surface finish, better heat resistance, and lower density variation. These features make it ideal for thin-film extrusion and woven sack production.
Manufacturers also notice better dispersibility and less dust during processing. This means cleaner workshops, stable extrusion pressure, and longer screw life. For small and medium converters, this translates directly into lower maintenance costs and fewer production stops.
Customer Feedback from Kenya
Several Kenyan customers shared positive reviews after trial runs. They highlighted the bright and clean film appearance and easy mixing ratio with virgin resin. One customer from Nairobi said, “Your sodium sulfate filler masterbatch gave us better film transparency and reduced weight per roll. That’s a win for both quality and economy.”
These consistent results have helped our brand build trust and reputation across East Africa. Demand has increased steadily over the past months, with repeat orders from packaging film and bag manufacturers.
Technical Highlights
Main ingredient: Sodium Sulfate (Na₂SO₄)
Carrier resin: PE / PP
Filler content: 70%–85%
Moisture: ≤ 0.1%
Advantages: Uniform dispersion, smooth film surface, low cost, eco-friendly composition
Expanding Presence in East Africa
Kenya has become one of our key destinations in Africa. The country’s manufacturing sector is rapidly developing, supported by growing demand for consumer packaging, agricultural films, and infrastructure materials. Our sodium sulfate filler masterbatch offers an affordable solution for these industries, helping converters balance cost and performance.
We are also in discussion with local distributors to set up warehouse stock in Mombasa for faster delivery and technical support. The goal is simple: to make quality masterbatch more accessible to East African manufacturers.
Commitment to Continuous Improvement
Customer feedback drives our innovation. Based on Kenyan clients’ suggestions, our R&D team is now optimizing the formulation to enhance compatibility with recycled polymers. This ensures smoother extrusion and more stable film output, even when mixed with PCR resin. We will continue adjusting production based on real user data, aiming for better dispersion, lower energy use, and more consistent color tone.
Looking Ahead
As the global plastics industry faces new challenges, steady quality and timely delivery remain our top priorities. The successful shipments during the National Day holiday show our operational strength and commitment to service. With growing recognition in Kenya and beyond, we look forward to deeper cooperation with customers in Africa and around the world.
We thank all our partners for their trust and continued support — and we promise to keep improving, even during holidays.
