Elastomeric foam insulation
Due to the high diffusion density combined with good thermal conductivity properties of elastomeric foam, it is ideal as an insulating material for cold media temperatures.
Elastomeric foam: everything you need to know
Also known as closed cell elastomeric foam insulation, abbreviated also frequently as FEF, or rubber insulation, elastomeric foam insulation is basically a synthetic rubber composed of a closed cell structure available in factory made tubes, sheets or rolls.
Manufactured by Kaimann since 1959, and thanks to a process that has been continuously improved since then. Our elastomeric foam insulation solutions meet the highest demands and set standards in energy efficiency, prevention of corrosion under insulation, noise and fire protection.
Why choose elastomeric foam for your insulation?
With its low water vapour permeability, closed cell structure, and integrated vapour barrier, elastomeric foam insulation is the optimal solution to control condensation. As a consequence, it protects piping and equipment from corrosion under insulation (also called "CUI") which occurs when water or moisture penetrate the insulation and attack the system.
- Moisture resistance
Elastomeric foam insulation is one of the best insulation materials for below ambient applications, where condensation is an issue.
- Excellent thermal insulation
Elastomeric foam insulation contributes to effectively manage heat gain/loss for the life of a mechanical system.
- Sound insulation
A very high level of sound reduction can be achieved through clever multi-layer construction.
- Health & Safety
Elastomeric foam insulation is safe for those who work and live with it, because it is mould- and microbial-resistant and has low-VOC emissivity. It is predestined for projects with high hygiene requirements.
- Durability and Installation
Due to the flexible nature of elastomeric foam, it is less susceptible to cracking, breaking, and material loss compared to rigid insulation solutions. Together with a smooth touch and feel it makes an installation more efficient and pleasant.
What can elastomeric foam insulation be used for?
Elastomeric foam insulation is suitable for a wide range of interior and exterior applications, including:
- Refrigeration piping, warm and cold-water lines, and chilled water piping
- HVAC equipment
- Interior and exterior duct systems
- Industrial insulation (including pharmaceutical, food & beverage)
- Marine and offshore insulation
- Solar installations
- Automotive (Bus, Truck and Camper/Caravan)

How does we make elastomeric foam insulation?
Elastomeric closed cell foam insulation is made in 3 steps…
Elastomeric closed cell foam insulation is manufactured on from different types of rubber. At Kaimann, the basic products are based on NBR rubber. For special applications, products based on EPDM or CR are also manufactured.
All products follow the same manufacturing process, the raw materials are put together in a large mixer. There, so-called master batches are produced, which can be compared with ready-made baking mixtures.Just before the material is extruded again and then runs into the furnace, the blowing agent is added. The shape is then heated in an oven, which changes the chemical foaming agent from a solid to a gas. At this time, thousands of tiny air pockets (cells) form, connected to each other. Then it is carefully cooled to ensure that these cells remain intact and do not break, maintaining the closed cell structure of the material. Finally, it is cut to size and packaged for shipping.
We has developed a specific granulate technology which guarantees the highest product quality and precise dimensions: halting the process at a certain point and turning the material into rubber granulate prevents premature reaction of the material and almost completely eliminates the shrinkage effect after production.
