Working with PVC Foam (Rigid, Structural Core) H130
Is PVC Foam (Rigid, Structural Core) easy to machine?
Cuts, routes and sands very easily with standard woodworking tools; avoid hot-wire cutting (evolves HCl) and use dust extraction.
Can PVC Foam (Rigid, Structural Core) be welded?
Not weldable; panels are joined by adhesive bonding, resin putty fillets or splicing into the laminate.
Can PVC Foam (Rigid, Structural Core) be formed, bent or molded?
Cross-linked grades take only mild heat-forming (~70–90 °C) or are supplied double-cut/scrim-backed for drapability; linear PVC grades thermoform readily to compound curves.
What surface finishes work on PVC Foam (Rigid, Structural Core)?
Sand faces, remove dust and prime with the matrix resin; closed cells keep resin uptake low but grooves/perforations should be filled during infusion for full bond.
PVC Foam (Rigid, Structural Core) chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
