Ask a question

Below are the most common questions. For technical queries, please get in touch with us.

What resins are suitable for the bonding of ROHACELL®?

The choice of adhesive depends on the required temperature resistance and the size of the area to be bonded. However, most adhesives are suited for Rohacell. The only concern is that the adhesive doesn’t bond by evapourating a solvent. Rohacell foam is nearly impermeable and it would take very long for the adhesive to cure.– For small areas we recommend a 2 component Epoxy resin.– For larger areas we recommend an Epoxy resin film.

Why does ROHACELL® with a lower density have a higher thermoforming temperature, yet can only withstand lower temperatures?

For many grades, Evonik use the same copolymer recipe to form different densities. In this case Evonik determine the final foam density by foaming temperature: the higher the temperature, the more the blowing agent expands and the lower the density. Foaming temperature and thermoforming temperature are related to some extent, the higher the foaming temperature, the higher the thermoforming temperature.

Can you machine ROHACELL® into complex designs?

Rohacell, a lightweight, high-strength rigid foam, can be machined using;

Laser cutting for precision and clean edges.
Hotwiring for smooth curves and custom shapes.
Thermoforming for molding complex geometries.
3 to 7-axis CNC machines for high-accuracy cuts.
Woodworking tools for straightforward, cost-effective modifications.

What industries are heat treated products used by?

Primarily HT customers are in the aircraft industry. The main benefit is the higher creep resistance in the process, i.e. the foam can be cured at higher temperatures and pressures without collapsing. Curing it at 180°C requires HT (Manual aircraft resins have to be cured at 180°C).

What would cause a collapse in the ROHACELL® foam?

If it is at room temperature: excessive mechanical loads. If the compressive strength limits are surpassed, cell walls will start crushing and the integrity of the foam will be lost. If it is at high temperatures: moisture.

What are emkay’s machining capabilities?

Emkay offers a comprehensive range of machining capabilities designed to meet precise specifications and deliver exceptional results:

• Horizontal Cutting Plant cuts ROHACELL® sheets to any thickness from 1mm with a guaranteed tolerance of +/- 0.5mm.

• Sanding Plant provides the option for ROHACELL® sheets to be finished with a guaranteed tolerance of +/- 0.2mm, with tighter tolerances available upon request.

• Laser Cutting utilises advanced laser cutting machines to shape ROHACELL® into any 2D designs with a precision tolerance of +/- 0.1mm.

• CNC Machining features 3 and 4-axis capabilities, with an optional 5-axis configuration available on demand for complex geometries.

• Vertical Band Saw offers precise cuts for custom shapes and sizes, tailored to meet specific project requirements.

If a machined component has been left for longer than expected, would ROHACELL® need to be dried out again?

As above, this depends on their curing process and also the relative surface of the part (the more surface per volume,the faster the foam will pick up moisture). The environmental conditions also play a role, with the foam picking up more moisture at higher relative humidity and temperature. Rohacell can generally be left for up to a day.

If a heat treated product is taken out of the heat sealed bags and not stored correctly, does it lose the heat treatment properties over time?

Yes, it does. Imagine HT as an extreme drying process. If exposed to moisture from the environment, molecules will absorb moisture over time and lose the HT properties.

At what stage of the process should the drying out of ROHACELL® be performed, before or after machining a component?

Machining doesn’t necessarily require drying. But if Rohacell has to be dried, it should be dried pior to machining. Drying after machining can lead to a distortion of the shaped part due to internal stresses. The curing process conditions determine how long the foam can be exposed to environmental moisture before it shows excessive creep. Evonik recommend avoiding the foam absorbing moisture for more than a day. Ideally machined parts should be stored in moisture-proof bags.

Can you heat treat IG-F, and if so, how long for and at what temperature? What properties would this hold?

For manufacturing procedures with curing temperatures between 125°C to 175°C, it is possible to heat treat IG-F. However, IG-F is intended for industrial applications that don’t require very high curing temperatures. Evonik have not heat treated this product and therefore have not produced a heat treated properties sheet.

What are the best glues to bond ROHACELL® to ROHACELL® and ROHACELL® to other materials?

Evonik recommend a 2 component Epoxy resin for small joining surfaces and a thermoplastic or thermoset film adhesive for a larger area.

Why is necessary to dry ROHACELL®?

The creep compression resistance behaviour can be improved by drying ROHACELL®.

What is the best process fordrying out ROHACELL®?

Please contact sales to discuss the drying options.
