Commercial Sectors

Target Industries

Heavy-duty twin corrugator and die-block extrusion line producing corrugated plastic conduit pipe
Industry Sector

Plastics & PVC Manufacturing Chemical Raw Materials Kenya

Kenya's plastics and PVC conversion sector—producing water pipes, electrical conduits, packaging films, and molded components—depends on precise compounding chemistry. Processing heat degradation, poor filler dispersion, and polymer brittleness can halt high-speed extrusion lines. KIKI'S supplies premium calcium carbonate extenders, plasticizers, lubricants, and PVC solvent cement reagents to leading converters.

Industry Sector

Paints, Coatings & Resins Chemical Raw Materials Kenya

Kenya's paints, decorative coatings, and wood finish manufacturing industry requires pure virgin solvents, high-brightness extender pigments, and specialized coalescing aids. A formulation is only as good as its raw materials: low-purity thinners cause pinholing and blushing, while coarse fillers destroy gloss and opacity. KIKI'S supplies premium solvents, extenders, and binders to East Africa's leading paint makers.

Process Compatibility
