ROHACELL® RIMA

Rigid foam with a fine cell structure

• ROHACELL® RIMA is a closed-cell rigid foam based on polymethacrylimide (PMI) chemistry that is completely free of CFC’s and specially designed to ensure the minimum possible uptake of resin.

Use less resin. Save weight and costs.

• The fine, closed-cell structure of ROHACELL® RIMA provides the unique benefit of allowing a minimal resin 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.

Thermoforming and shaping

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

• ROHACELL® RIMA foam is particularly well-suited for vacuum infusion and RTM processes where the fine- cell foam can also be used purely as a fly-away tool.
• 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 a temperature of 180 °C (356 °F) and pressures up to 0.7 MPa (102 psi).
