G-Etronax PM H - Sheet

PM H is the mechanically strongest grade in the PM series (GPO 1), used e.g. as thermal insulation plates in constructions that require high-strength properties.
Only available as sheet.

PM H vs. PM 953

PM H and PM 953 are the two most mechanically comparable grades in the PM series: PM H reaches 250 MPa bending strength against PM 953's 180 MPa. Both share the same CTI of 600. PM H goes further still, offering the highest mechanical class in the series, though it's positioned as a thermal class H material rather than as a straightforward upgrade path from PM 953.
