What is the mixing ratio of Polyol and Isocyanate?

For rigid insulation foam systems, the mixing ratio is typically 1:1 by volume or 100:110 by weight (Polyol to Isocyanate).

What is the difference between Flexible and Rigid Polyurethane Foam?

Flexible PU foam has an open-cell structure for soft mattresses and seating, whereas Rigid PU foam has a closed-cell structure for thermal cold room insulation.

Where can I buy Polyurethane Foam chemical kits in Nairobi?

Kiki's Industrial Chemicals stocks matched Polyol and Isocyanate drum sets (450kg total) at our warehouse in Nairobi Industrial Area.

How fast does Polyurethane Foam react once mixed?

Once Polyol and Isocyanate are thoroughly mixed, cream time is 10-15 seconds, gel time is 60-90 seconds, and tack-free cure occurs in 3-5 minutes.

What safety precautions are required when handling Isocyanate (MDI)?

Isocyanates are respiratory sensitizers. Always wear organic vapor respirators, eye protection, nitrile gloves, and work in well-ventilated areas.

What is the free rise density of Kiki's rigid polyurethane foam system?

Our rigid polyurethane insulation system produces a free rise core density of 35-40 kg/m³, delivering superior compressive strength and thermal insulation.

How should Polyol and Isocyanate drums be stored?

Store in original sealed steel drums indoors between 15°C and 25°C. Isocyanate is sensitive to moisture and will skin over if exposed to air.

Do you supply mattress factories and cold room contractors across Kenya?

Yes, we supply PU foam raw materials to mattress manufacturers, insulation contractors, and solar heater makers nationwide.

What packaging sizes are available?

We supply Polyurethane Foam systems in matched 450kg drum sets (200kg Polyol + 250kg Isocyanate) and 1,000kg IBC totes.

Do you export PU foam chemicals to East Africa?

Yes, we export Polyurethane chemical sets to insulation contractors and mattress makers in Uganda, Tanzania, and Rwanda.

Can these chemicals be used for spray foam insulation?

Yes, we supply formulated Polyol grades specifically tailored for high-pressure spray foam insulation rigs.
