Working with PVC Foam Board CELUKA

Is PVC Foam Board easy to machine?

Cuts, drills and CNC-routes like hardwood with carbide tools and high rake; use vacuum hold-down, moderate speeds and chip evacuation to avoid heat smearing of the cell walls.

Can PVC Foam Board be welded?

Hot-air/hot-plate welding and PVC solvent cement or PU/cyanoacrylate adhesives work on the skin, but weld and bond strength is limited by the low-density foam core; screws should be coarse-thread or bushed.

Can PVC Foam Board be formed, bent or molded?

Line-bend or thermoform at about 120–150 °C (sheet temperature); avoid deep draws since cells collapse and thickness/density change locally — extruded only, not injection-moulded.

What surface finishes work on PVC Foam Board?

Accepts screen, UV and solvent digital printing, vinyl films, and acrylic/PU paints directly after cleaning; cut edges are porous and should be sealed or edge-banded, and no true polish is achievable.

PVC Foam Board CELUKA — frequently asked

What is PVC Foam Board CELUKA used for?

PVC Foam Board CELUKA is typically used for signage boards, display panels, cabinet/furniture panels, bathroom/marine cladding and lightweight structural panels. In short: lightest routable PVC sheet; best-machining rigid foam; weather-resistant sign panel.

What is the tensile strength of PVC Foam Board CELUKA?

PVC Foam Board CELUKA has a typical tensile strength of 14 MPa (2.03 ksi) — weaker than 75% of polymer grades. Strength varies by condition: see the 7 listed tempers.

Is PVC Foam Board CELUKA easy to machine?

Yes — machinability is rated excellent (85/100, better than 88% of polymer grades). Cuts, drills and CNC-routes like hardwood with carbide tools and high rake; use vacuum hold-down, moderate speeds and chip evacuation to avoid heat smearing of the cell walls.

Can PVC Foam Board CELUKA be welded?

Yes — weldability is rated good (60/100). Hot-air/hot-plate welding and PVC solvent cement or PU/cyanoacrylate adhesives work on the skin, but weld and bond strength is limited by the low-density foam core; screws should be coarse-thread or bushed.

What surface finishes work on PVC Foam Board CELUKA?

Accepts screen, UV and solvent digital printing, vinyl films, and acrylic/PU paints directly after cleaning; cut edges are porous and should be sealed or edge-banded, and no true polish is achievable.

Can PVC Foam Board CELUKA be formed, bent or molded?

Line-bend or thermoform at about 120–150 °C (sheet temperature); avoid deep draws since cells collapse and thickness/density change locally — extruded only, not injection-moulded.

What is the maximum service temperature of PVC Foam Board CELUKA?

PVC Foam Board CELUKA is rated for continuous use to about 60°C (140 °F), and briefly to 70°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between PVC Foam Board FF-0.50 and PVC Foam Board CELUKA?

FF-0.50 is the default condition — default all-purpose signage/display board: best balance of weight, screw holding and price. CELUKA: pick when a hard, smooth, print/paint-ready surface and better screw/edge strength are needed at similar overall weight.
