Rohacell RIMA

THE FINEST CELLS FOR MINIMAL RESIN UPTAKE

The cell structure of ROHACELL® RIMA has been specially designed to ensure the minimum possible uptake of resin. This is approximately 50 g/m², which allows the end weight of the component to remain extremely low. The thermal and thermomechanical properties of the rigid foam are otherwise similar to those of ROHACELL® WF or ROHACELL® RIST.

The extremely fine-celled material is used for infusion components in aeronautic and aerospace applications, as well as in sports equipment and in automotive construction.

ROHACELL® RIMA 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 and temperatures of up to 130°C. The heat-treated material ROHACELL® RIMA-HT can be used at a temperature of 180°C and pressures of up to 0.7 MPa.

Description

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.

PROCESSING AND PRODUCTION ROHACELL®

RIMA foam is particularly well-suited for vacuum infusion and RTM processes where the fine[1]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). 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 Chem-craft Shapes Department.
