The whole polyurethane recipe, from one supplier
Every polyurethane foam starts with two liquids: a polyol and an isocyanate. Elrisa supplies both sides, plus the catalysts, silicones, flame retardants and blowing agents that turn them into the foam you sell.
- ELRIPOL polyols for flexible, rigid and CASE uses, with published typical properties.
- ELRIFOAM systems: ready-to-use foam systems for spray, sandwich panels, appliances and pipes. Just add MDI.
- Technical help from our laboratory in Kasoa, from the first formula to full production.

Soft, springs back
Open-cell foam for mattresses, furniture, car seats and packaging. Made from long-chain polyols (molecular weight 3,000–8,000) with TDI or MDI, usually blown with water.
Hard, insulating
Closed-cell foam for panels, cold rooms, refrigerators, pipes and spray insulation. Made from short-chain, high-functionality polyols with polymeric MDI. One of the best insulators available.
Tough and elastic
Shoe soles, rollers, wheels, sealants, adhesives and coatings use diols and triols with modified MDI or TDI prepolymers and curing agents.
The all-rounder
Made from propylene and ethylene oxide on a starter such as glycerine, sucrose or sorbitol. Used in almost all flexible foam and as the backbone of rigid foam. Hydroxyl value sets how hard or soft the foam is.
Fire and stability
Aromatic polyesters improve flame resistance, char and dimensional stability in rigid foam, which is why spray and panel systems use them. Often blended with polyether polyol.
Firmness without weight
Polyether polyol carrying fine SAN particles. Raises the hardness and load-bearing of flexible foam, so you reach the firmness you want at a lower density.
Polyol and PU foam questions
What chemicals do I need to make polyurethane foam?
Polyurethane foam is made by mixing two liquids: a polyol side and an isocyanate side. For flexible foam such as mattresses you need a flexible polyether polyol (often with a polymer polyol for hardness), TDI or MDI, water as the blowing agent, amine and tin catalysts, a silicone surfactant and optionally methylene chloride, flame retardant and colour. For rigid insulation foam most producers buy a ready-made blend polyol system and react it with polymeric MDI. Elrisa supplies all of these and can work out the exact recipe with you.
How do I start a foam mattress factory?
Start by deciding the foam grades and daily output you want, then choose a production method (box foaming for small starts, a continuous slabstock line for larger volumes), the cutting equipment and a reliable supply of polyol, TDI and additives. Elrisa helps new foam makers through each step: formulation, raw material lists and costs, equipment advice, trial batches in our laboratory, staff training and ongoing supply. Fill in the foam production form and we will contact you.
What is the difference between polyether and polyester polyol?
Polyether polyols are made from propylene and ethylene oxide on a starter such as glycerine or sucrose. They are used in almost all flexible foam and in many rigid foams. Aromatic polyester polyols are made from acids and glycols. They are used in rigid insulation foam because they improve flame resistance and dimensional stability. Many rigid foam formulas blend the two.
What is a blend polyol or PU foam system?
A blend polyol, also called a system or component A, is a ready-mixed polyol side that already contains the catalysts, surfactant, flame retardant and blowing agent. You only add the isocyanate (component B, usually polymeric MDI) in the stated ratio. Systems make rigid foam production simpler and more consistent, which is why spray, panel and appliance producers use them. Elrisa's ready-to-use systems are sold as ELRIFOAM.
What is the difference between rigid and flexible polyurethane foam?
Flexible foam is soft and springs back. It is used in mattresses, furniture, car seats and packaging, and is made from long-chain polyols (molecular weight 3,000 to 8,000) with TDI or MDI. Rigid foam is hard, closed-cell and insulating. It is used in panels, cold rooms, refrigerators, pipes and spray insulation, and is made from short-chain, high-functionality polyols with polymeric MDI.
Do you ship polyols and PU chemicals worldwide?
Yes. Elrisa ships polyols, foam systems, MDI, TDI and additives to customers in Africa, the Middle East, Asia, Europe, the Americas and Oceania, by sea to your nearest port and onward by road where needed. In Africa we deliver to ports such as Tema, Lagos, Abidjan, Dakar, Douala, Mombasa, Dar es Salaam, Durban and Alexandria. We quote FOB, CFR, CIF, DAP or DDP terms.
How are polyols and isocyanates packed and stored?
Polyols and isocyanates are shipped in 200 to 250 kg steel drums or 1,000 to 1,250 kg IBC tanks, and in bulk for large users. Keep them sealed, dry and out of direct sun. Isocyanates react with moisture, so close containers straight after use and follow the Safety Data Sheet. We send the TDS and SDS with every order.
Is HCFC-141b still allowed for PU foam?
HCFC-141b is being phased out worldwide under the Montreal Protocol, and many countries already ban or restrict it in foam. Elrisa offers water-blown, pentane, cyclopentane and HFC-245fa systems, and will advise on the rules in your country before you choose a system.
How much do polyols cost?
Prices depend on the grade, the quantity, the packaging and the delivery port, and they follow the international oil and chemical markets. Send the order form on this page with your products, quantities and destination and we reply with a written quotation, usually within 24 hours.
