AtlasFoam® is an expanded material of closed cells produced from a reticulated polymer of high strength and toughness in relation to the density.
AtlasFoam® is suitable as a core for structural sandwich, ideal for different applications in the marine industry, aerospace, wind energy and for all of those sectors in which lightness and high resistance are required, as well as resistance to environmental degradation (internal or external environments, contact with water, presence of oils, etc.).
The products of SotecoFoam are extremely versatile because they combine different qualities in single products. For this reason they can be used for the construction of main structures, thanks to their mechanical resistance, for the laying of wall plugs, partitions, protection structures, and in every other application in which good insulation and inalterability are required in different environmental conditions.

Divinycell F recyclable, prepreg compatible sandwich core represents a significant breakthrough in core material development. In addition to offering excellent FST (fire, smoke and toxicity) properties, it also has good mechanical properties and processing characteristics.
High Performance Applications
With its combination of excellent fire properties, good mechanicals and processing characteristics, Divinycell F is ideal for a wide variety of commercial aircraft interior applications.
It more than exceeds the US and European regulatory requirements for commercial aircraft interiors and is used for such components as wall paneling, ceiling modules, luggage bins and doors/lockers. Its close cell structure makes it particularly suitable for galleys and toilets.
Divinycell F is particularly fast and easy to process and does not require edge filling.

With its unique combination of features - low weight /high strength, wide processing envelope and high temperature performance - prepreg compatible Divinycell HP is ideal for a wide range of applications in the marine, wind energy, transportation and industrial markets.
Temperature Performance
With its high processing temperature, Divinycell HP can be processed at a much higher temperature than other polymer core materials in general use, making it suitable for not only low but also medium temperature prepregs.
Its elevated temperature performance is not just beneficial to prepreg users. Its high residual strength and good dimensional stability also make it ideal for vacuum bagging, infusion and RTM (resin transfer molding). HP's elevated temperature performance also extends to the 'in service' life of the component. Divinycell HP will retain a high percentage of its mechanical properties despite long term exposure to high ambient temperatures.
Strength Performance
Divinycell HP exhibits at both ambient and elevated temperatures impressive compression and shear properties (normally the most important for a sandwich core material) that are better than other commonly used ‘elevated temperature’ core materials. The figures for shear strain show that HP has good ductility and energy absorption characteristics. Testing has shown that HP also outperforms linear cores in terms of slamming resistance.
Adhesion
Divinycell HP also excels is in adhesion. Peel tests have been performed using commonly used resin systems and prepregs with superior results to other cores used for prepregs.

For more than 30 years Divinycell H has been the first choice of leading producers of sandwich composite structures around the world. During this time the properties of Divinycell H have been continuously enhanced and improved so that it continues to be ideal for the vast majority of sandwich composite applications.
Ideal for a Wide Range of Applications
Divinycell H has been widely used over many years in virtually every application area where sandwich composites are employed. These include the marine (leisure, military and commercial), land transportation, wind energy, civil engineering/infrastructure and general industrial markets.
Material & Process Compatibility
Divinycell H is compatible with virtually all commonly used resin systems (polyester, vinyl ester and epoxy) including those with high styrene contents. Its good temperature performance with high residual strength and good dimensional stability, makes Divinycell H ideal for hand laminating, vacuum bagging, RTM (resin transfer molding) and other closed molding processes.
Mechanical Properties
In its application range Divinycell H has the highest strength to density ratio. It exhibits at both ambient and elevated temperatures impressive compressive strength and shear properties (normally the most important for a sandwich core material).

SotecoFoam created FenixFoam®, the innovative expanded structural panel made of fine closed cells suitable for the transportation industry, aeronautics, marine and for all those areas that require materials with good fire reaction.
In order to achieve FenixFoam®'s special formulation, different mineral fillers have been used.
These undergo a reaction ahead of the flame front, providing substances that steer the polymer decomposition towards the formation of graphitic-refractory substances.
These hinder the fire propagation and only permit the development of low-density smoke.
FenixFoam® is tested in certified laboratories for fire reaction according to the AFNOR rules for smoke opacity and gas combustion during pyrolysis. Because of its behaviour in fire circumstances, it is classified in the F1 and M1 classes. When it is involved in a fire, the development of FenixFoam®'s low-density smoke does not prevent anyone from reaching the emergency exits. The low toxicity of the gas is also very important because it does not prevent people from escaping the fire.

CrioFoam® is a structural foam characterized by a low thermal conductivity, due to the special formulation and type of of expanding agents, which permits energy savings of up to 20%. The foams are composed of polymeric structures of cross-linked high density for an excellent resistance to styrene, suitable for unsaturated polyester resins, epoxy resins, and vinylester resins. Not only does its regular and fine structure guarantee excellent thermal properties, but also excellent mechanical properties and dimensional stability.
CrioFoam® is available with fire reaction to the DIN B2 standard.
CrioFoam® finds its application in the construction of sandwiches for all those applications in which very good thermal insulation is required, such as in the case of industrial containers and refrigerator vans for the preservation of food products.

MouldFoam® has been developed and produced for the production of models, prototypes and industrial moulds. The material shows an excellent workability, both with traditional tools and with the most sophisticated new generation machinery.
Thanks to its high isotropy, the material is workable with many different types of equipment and the feed rate is independent of the manufacturing direction. The worked surfaces show a very little porosity, especially with the higher density grades.
MouldFoam® comes in different densities in order to satisfy the various final applications of the product.
