Overview

ROHACRYL™ SW is a closed cell foam with a fine, homogeneous cell structure that is free of harmful CFC’s. The small cell size makes it possible to keep resin absorption at the surface of the foam core to a strict minimum.

This rigid foam product is ideal for lightweight sandwich construction in a wide variety of applications in industries like sports equipment, lifestyle, marine and subsea, as well as automotive and industrial markets.

Process Benefits

ROHACRYL™ is easy to machine with the ability to cut it quickly and cleanly. The compatibility with automated handling systems due to closed cells and the high processing temperature are a requisite for shorter cycle times.

The result is increased production efficiency from start to finish. ROHACRYL™ is the foam of choice for automated, high-volume production with RTM and infusion processes. It addresses the needs of the whole design and production chain with excellent mechanical properties at low densities, low resin absorption and high process temperatures.

Sustainability

The recyclable raw material base of ROHACRYL™ offers a low carbon footprint and a clean end-of-life solution. Low resin consumption, a leaner design, and short cycle times are additional levers for responsible production in our global environment.

Future-proof your applications for the challenges of a circular economy – without any harmful CFCs!
