Processing and Production

Of all the ROHACELL® grades, it is the grade that is best suited to withstand the most demanding process conditions: curing temperatures of up to 180 °C (356 °F) and pressures as high as 0.45 MPa (65 psi).; After heat treatment, ROHACELL® XT-HT can even be used at temperatures of 190 °C (374 °F) and pressure of 0.7 MPa (102 psi) dependent upon density. Typical curing temperatures of BMI resin system of up to 210 °C (410 °F) can be applied in a pressureless post-cure process.; These extreme properties make ROHACELL® XT the ideal foam for use with BMI resins, among other materials.; ROHACELL® XT foam is suitable for autoclave technologies, vacuum infusion, RTM and VARTM processes.
