Minimal resin uptake
ROHACELL® RIMA is engineered with an extremely fine cell structure, allowing minimal resin absorption (~50 g/m²), keeping final component weight to a minimum.
High-temperature processing
The heat-treated version, ROHACELL® RIMA-HT, can withstand curing temperatures up to 180 °C and pressures of 0.7 MPa, making it suitable for vacuum infusion and RTM processes.
Applications
Designed for lightweight applications, ROHACELL® RIMA is ideal for aerospace and sports equipment requiring a low-density yet high-strength core material.
