Direct supply line of custom-compounded granules optimized for tropical processing conditions.
The Democratic Republic of the Congo (DRC) is undergoing a major industrial transformation. Driven by heavy mining activities in the southern Katanga Copperbelt, extensive urban development in metropolitan Kinshasa, and the rollout of essential public utility projects, the demand for versatile polymer materials has reached an all-time high. PVC (Polyvinyl Chloride) granules serve as the foundational raw material for many of these operations.
However, the climatic and geographic conditions in Central Africa present unique challenges for plastics manufacturing. Products must withstand constant exposure to intense ultraviolet radiation, high humidity, and elevated thermal conditions. Consequently, standard global formulations of PVC compounds often fail prematurely, leading to degradation, loss of tensile strength, and cracking. As a specialized manufacturer, Jiangsu Dahai Plastics Co., Ltd. supplies customized formulations specifically tailored to meet these environmental demands.
Acid-resistant pipes, slurry ductings, and heavy-duty wire sheathings designed for deep-shaft cobalt and copper mining sites across Kolwezi and Lubumbashi.
Rigid PVC pipe compounds for clean water systems and municipal sewage pipes, optimized to prevent chemical leaching and degradation in tropical soils.
Flexible PVC compounds resistant to high levels of UV exposure, ensuring long service lives for surface and sub-surface irrigation tubing.
The global PVC manufacturing industry is shifting toward high-tech, environmentally stable, and lead-free additives. In the European and North American markets, non-phthalate plasticizers and Calcium-Zinc (Ca-Zn) stabilization systems are standard. However, the Central African market has historically been supplied with lower-grade PVC inputs containing heavy metal stabilizers, which pose health and regulatory risks.
Jiangsu Dahai Plastics is addressing this gap. We supply lead-free, RoHS-compliant PVC compounds to the DRC market. Our goal is to ensure that local fabricators can manufacture export-ready goods that meet strict international standards, including EN-71 and REACH compliance.
Delivering high-volume polymer feedstocks to DRC destinations requires careful logistics planning. For operations in the western region (such as Kinshasa and Boma), cargo is shipped directly via the Port of Matadi. For eastern and southern mining zones, materials are routed through corridors from Dar es Salaam (Tanzania) or Durban (South Africa) to cross border points in Kasumbalesa. In all cases, selecting moisture-proof, heavy-duty container packaging is crucial to prevent contamination of the polymer pellets during transit.

Founded & Established
To support manufacturing across the DRC, we offer specialized PVC granule formulations designed for specific processing applications:
During the equatorial rainy season, footwear must be durable and resistant to water damage. Our transparent and translucent soft PVC granules, with a Shore hardness of 60-70A, are ideal for manufacturing rain boots and sandal soles. These compounds offer strong tear strength, slip resistance, and flex-life indicators that withstand rough terrains.
Healthcare facilities across the DRC require high-quality, non-toxic disposable equipment. Our medical-grade PVC films and raw materials are used to manufacture urine drainage bags and enteral feeding bags. These compounds are sterilized, highly transparent, and free from heavy metal stabilizers.
| Application Type | Recommended Shore Hardness | Key Performance Indicators | Compliance Standards |
|---|---|---|---|
| Industrial Cables & Wires | 75A - 90A | High Dielectric Strength, Flame Retardant (LOI > 30%) | IEC 60227, RoHS |
| Footwear (Soles & Boots) | 60A - 70A | Abrasive Resistance < 150mm³, Dynamic Flex Life | EN ISO 20344 |
| Medical Bags & Tubes | 55A - 65A | High Clarity, Autoclave Sterilizable, Non-phthalate option | USP Class VI, ISO 10993 |
| Rigid Pipes & Fittings | 75D - 85D | Impact Strength > 10 kJ/m², Tensile Modulus > 2500 MPa | ISO 1452, BS EN 1401 |
Modern commercial buildings in Kinshasa require durable interior materials. Our rigid and semi-rigid PVC sheet compounds are used to produce SPC flooring wear layers, decorative lamination panels, and building structural components. These materials offer flame-retardant properties and low smoke emissions.
A Trusted Partner in Polymer Extrusion & Compound Science Since 1996
Jiangsu Dahai Plastics Co., Ltd. is a major polymer manufacturer operating a state-of-the-art 120,000 square meter production complex. With over 20 advanced production lines and a dedicated workforce of 450+ employees—including 30% technical specialists—we produce more than 100,000 tons of high-grade PVC compounds, sheets, and films annually. Our global sales exceed USD 180 million, reflecting our reach across South America, Southeast Asia, and Africa.
We maintain an in-house laboratory accredited by the China National Commission for Conformity Assessment (CNAS). Our facility is equipped with advanced analytical testing equipment, including Agilent Gas Chromatography (GC) analyzers, universal testing machines, gloss meters, and environmental cold-tolerance testing chambers. This ensures that every batch of PVC granules shipped to the DRC performs reliably in tropical environments.
Every batch undergoes testing for plasticizer migration, thermal stability, tensile elongation, and color fastness before export.
Our formulations are compliant with REACH, EN-71, ASTM-F-963, and RoHS guidelines, protecting downstream users.
We adjust hardness, UV-resistance, and flame-retardant properties to match your machinery and performance needs.
Industrial sustainability is becoming increasingly important in Central Africa. As regulatory bodies in the DRC implement stricter environmental policies, local manufacturers must adopt clean polymer technologies. Our technical roadmap focuses on introducing eco-friendly raw materials without compromising performance:

Expert answers to common technical, regulatory, and logistics questions for importing PVC raw materials into the DRC.
We adjust our formulations by incorporating premium thermal stabilizers and UV-absorbers during compounding. This prevents thermal degradation during extrusion and helps products maintain their structural integrity when exposed to sunlight in Central Africa.
Yes. All our medical-grade and consumer goods PVC granules comply with REACH, RoHS, EN-71, and ASTM-F-963 standards. We verify compound safety in our CNAS-accredited laboratory to ensure they are free from heavy metal stabilizers and harmful plasticizers.
Shipments bound for southern mining hubs like Lubumbashi are typically routed through the Port of Dar es Salaam (Tanzania) or Durban (South Africa), followed by road transit through Kasumbalesa. Transit times range from 35 to 45 days after dispatch from our manufacturing facility in China.
Yes. We custom-compound PVC granules to hardness ranges from 50 Shore A (highly flexible) to 90 Shore D (highly rigid). We can also color-match compounds using standard RAL or Pantone color systems to fit your production specifications.
We package our PVC granules in heavy-duty, moisture-proof PP woven bags lined with internal PE bags. We also line our shipping containers with protective barriers to prevent humidity build-up during long sea voyages through tropical zones.
Our standard MOQ for custom formulation runs is 10 metric tons. For standard clear/translucent flexible compounds, we can accommodate smaller trial orders. Please contact our sales engineers to discuss your project requirements.
