MILLIFOAM® Rohacell® IG-F - The Industrial Standard

With Rohacell® IG-F we provide the standard industrial grade from Evonik.

It is the foam of choice for automotive, watercraft, electronics, medical and other industrial applications. Additionally, it is a commonly used core material for x- ray and CT tabletops in the technology medical market.

Rohacell® IG-F is characterized by a fine cell structure and a minimal resin uptake at the surface, where the cells have been gentle cut open with our MILLIFOAM® slicing technology. Less resin uptake during part processing means lower final part weight and reduced overall cost.

MILLIFOAM® Rohacell® IG-F thin hard foam sheets give maximum freedom in design, because it can be thermoformed and tailored into complex high-precision geometries with the 4a MILLIFOAM® Shaping service.

It is suitable for prepreg processing, resin infusion and RTM process up to temperatures of 130°C (266°F) and pressures of 0.3 MPa (44 psi).

MILLIFOAM® Rohacell® Hero – The Aircraft Standard

With Rohacell® Hero we provide Evonik’s standard in aircraft.

Rohacell® Hero is qualified by AIRBUS under AIMS 04-11-011 and ABS5955 standard for aircraft structural parts.

With this qualification and in combination with its outstanding mechanical behaviour, it is the recommended core material in composite structures for aircraft wings, landing gear doors, radomes, vertical and horizontal stabilizers, ailerons and other areas subjected to surface impact damage.

Compared to other core materials, Rohacell® Hero has excellent elongation at break properties and less water ingress, which is important to withstand the flexural loads and mechanical stresses.

Rohacell® Hero has a medium cell structure to ensure good bonding and shear strength. In combination with our MILLIFOAM® technology, the cells on the surface have been gentle cut open and allow a minimized resin uptake only in the cut surface cells. This results in a lighter finished part weight, e.g. compared to traditional honeycomb structures.

With a heat resistance of up to 210°C (428°F), processing or curing temperatures can be increased which results in a significant reduction in total cycle time and faster component manufacturing.

No other foam core material offers such a wide variety of processing, including autoclave, resin infusion, RTM and VARTM processes.

MILLIFOAM® Rohacell® Hero thin hard foam sheets give maximum freedom in design, because it can be thermoformed and tailored into complex high-precision shapes by the 4a MILLIFOAM® Shaping service.

MILLIFOAM® PVC

MILLIFOAM® Divicell®H - The Excellent Grade

With Divinycell® H we offer Diab’s unique PVC formulation with excellent mechanical properties to a low weight.

The unique polyvinylchloride (PVC) chemical structure of Divinycell® H is ideal for applications subjected to fatigue, slamming or impact loads. With its excellent mechanical properties to weight, Divinycell® H is widely used the foam of choice for marine, land transportation, wind energy, civil infrastructure and general industrial markets.

Divinycell® H is compatible with all commonly used resin and manufacturing systems. The foam has an excellent chemical resistance, a low water absorption and a good thermal/acoustic insulation behaviour. It can be processed at temperatures up to 90 °C, whereby maximum processing temperature depends on time, pressure and process conditions. It’s continuous operating temperature is typically -200 °C to +70 °C.

In combination with our MILLIFOAM® technology, we provide Divinycell® H structural PVC foam core in a standard thickness range from 0,5mm to 5,0mm and with superior, dust-free surface quality.

MILLIFOAM® PEI

MILLIFOAM® UltemTM XP - The Dielectric Core

With Ultem™ XP we offer original high frequency foam grade from Sabic.

Ultem™ XP is characterized by an extremely low dielectric constant and particularly favorable transmission properties in the high frequency region. This makes it to a favoured core material for the use in our CIMERA® micro-sandwich radomes for 5G mmWave small cell antennas, SatCom and SatCom on the move applications .

With our MILLIFOAM® technology, we provide Ultem™ XP in a thickness range starting from 1,0mm up to 2,5mm. In combination with its outstanding FST performance, Ultem™ XP is an excellent candidate as core material in composite structures for military and aerospace applications, where structural fire performance, radar transparency and/or extreme hot and cold environments are required.

MILLIFOAM® Ultem™ XP thin hard foam sheets give maximum freedom in design, because it can be thermoformed and tailored into complex high-precision geometries by using our 4a MILLIFOAM® Shaping service.
