Cross-linked PVC Foam Core GS vs Cross-linked PVC Foam Core H80
Composite · Cross-linked PVC Foam Core grade comparison
Cross-linked PVC Foam Core GS and Cross-linked PVC Foam Core H80 are two grades of the same composite grade, Cross-linked PVC Foam Core: GS (grooved/scored & perforated infusion sheet) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. Cross-linked PVC Foam Core H80 is the stronger of the two: tensile strength 3 MPa (0.363 ksi) against 2 MPa (0.305 ksi) for Cross-linked PVC Foam Core GS, about 19% more. Cross-linked PVC Foam Core H80 is stiffer (0.1 GPa vs 0.08 GPa) and Cross-linked PVC Foam Core GS conducts heat better (0.04 W/m·K vs 0.03 W/m·K).

Cross-linked PVC Foam Core GS vs Cross-linked PVC Foam Core H80: 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.
