ROHACELL® RIMA
RIGID FOAM WITH A FINE CELL STRUCTURE

PROCESSING AND PRODUCTIONROHACELL® RIMA is a closed-cell rigid foam basedon polymethacrylimide (PMI) chemistry that iscompletely free of CFC’s and specially designed toensure the minimum possible uptake of resin.

ROHACELL® RIMA foam is particularly well-suited forvacuum infusion and RTM processes where the finecell foam can also be used purely as a fly-away tool.

USE LESS RESIN. SAVE WEIGHT AND COSTS.
The fine, closed-cell structure of ROHACELL® RIMAprovides the unique benefit of allowing a minimalresin uptake of only approx. 50 g/m2.
This eliminates excess and unnecessary resin that
adds undesirable weight and cost to a finished part.
The end weight of the finished component remains
extremely low.

Processing is possible at a pressure of 0.7 MPa(102 psi) and temperatures up to 130 °C (266 °F).
Heat-treated ROHACELL® RIMA-HT can be used at atemperature of 180 °C (356 °F) and pressures up to0.7 MPa (102 psi).

THERMOFORMING AND SHAPINGROHACELL® RIMA can be easily thermoformed or
CNC machined to meet customer requirements.
High precision, pre-shaped and ready-to-use foamcores in complex or simple geometries can also be
supplied by the ROHACELL® Shapes Department.
