PVC Countertop SubstrateFiller
Residential material guide
Rigid PVC foam board: closed-cell polyvinyl chloride structural filler (density: 0.5–0.7 g/cm³, ASTM D1622) for Fadior stainless steel countertop assemblies.
This engineered core material functions as a low-density structural matrix that balances weight reduction with thermal isolation. The chemical structure consists of rigid PVC resin (polyvinyl chloride homopolymer, suspension grade K-67) expanded with azodicarbonamide blowing agents to create a uniform cellular matrix with 95%+ closed-cell content.
Overview
What this surface adds to the room.
The resulting material is chemically inert and hydrophobic, achieving water absorption: <1% (ASTM D570, 24h immersion) and moisture vapor transmission: <0.1 perm (ASTM E96).
Fadior specifies **Type VII rigid PVC foam board** (per ASTM C591 classification for cellular plastics) with a nominal density of 0.55 g/cm³ for standard countertops and 0.70 g/cm³ for heavy-load island applications. This density gradient allows optimization across product lines without changing base chemistry.
In Fadior's manufacturing ecosystem, this filler serves as the substrate beneath 304 food-grade stainless steel skin (ASTM A240 / EN 1.4301, 1.2mm nominal thickness). Unlike traditional particleboard or plywood cores using urea-formaldehyde binders (emission class E1-E2, EN 13986), Fadior's PVC filler contains zero added formaldehyde, verified by chamber testing per EN 16516 (<5 µg/m³ detection limit).
The thermal conductivity of this specific grade is 0.035–0.040 W/m·K (ASTM C518), functioning as an intentional thermal break to prevent heat transfer from cookware to cabinetry.
Material note
Chosen for daily contact
They matter most where hands, heat, utensils, and visual wear all meet at one working surface.
Material note
Works by contrast
The value here is not to imitate steel, but to give the system a calmer counterpoint in tone and texture.
