Aluminum Composite Panel (ACM) vs Linear PVC Foam Core
Composite · grade comparison
Aluminum Composite Panel (ACM) and Linear PVC Foam Core are both composite grades. Aluminum Composite Panel (ACM) is the stronger of the two: tensile strength 130 MPa (18.9 ksi) against 2 MPa (0.247 ksi) for Linear PVC Foam Core, about 76 times as much. In exchange, Linear PVC Foam Core is the more ductile: elongation 30% versus 5% for Aluminum Composite Panel (ACM). Linear PVC Foam Core is lighter (0.09 g/cm³ vs 1.35 g/cm³ for Aluminum Composite Panel (ACM)) and Aluminum Composite Panel (ACM) is stiffer (70 GPa vs 0.05 GPa). On the shop floor, Linear PVC Foam Core machines more easily (excellent vs very good) and Aluminum Composite Panel (ACM) sits in a lower cost tier (standard, $$) than Linear PVC Foam Core (high, $$$$).
Aluminum Composite Panel (ACM)Choose it when strength drives the design, or when the part sees heat.
Linear PVC Foam CoreChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Aluminum Composite Panel (ACM) vs Linear PVC Foam Core: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
