Form Core Series

Form Core High-Density Flat Surface WPC Form Panel for Interior Wall

Wood-plastic composite form panel engineered for interior wall applications requiring flatness, structural rigidity, and moisture resistance.

Thickness 5 mm

Density 0.6 g/cm³

Width 122 cm

Lengths 7 options

Length range 2.44m to 4.0m

Water absorption Less than 0.5%

Fire rating Class B1

Flexural strength 32 MPa

This high-density WPC form panel is manufactured from wood-plastic composite with a flat surface finish. The 5 mm thickness provides structural rigidity for interior wall applications. Panel width is 122 cm with density of 0.6 g/cm³ achieving balance between strength and weight. Length options range from 2.44 m to 4.0 m in seven increments. The flat surface accepts paint, wallpaper, or decorative film application. Suitable for residential and commercial interior wall cladding where panel flatness is specified.

D

High-Density Form Core

0.6 g/cm³ density provides consistent flatness across the panel surface. The form core eliminates surface waviness common in lower density panels, ensuring uniform finish for paint and wallpaper applications.

F

Flat Surface Finish

Smooth, non-porous surface ready for decorative finishing. Accepts liquid paints, vinyl wraps, and wallpapers without additional sealing. Surface flatness tolerance of ±0.3 mm per linear meter.

W

Waterproof Composition

Closed-cell WPC structure with water absorption below 0.5 percent prevents swelling, warping, or mold growth in high-humidity interior environments such as bathrooms and kitchens.

S

Dimensional Stability

Linear expansion coefficient of 0.045 mm per meter per degree Celsius. Formulation resists warping, curling, and edge cupping across seasonal humidity and temperature changes.

Frequently Asked Questions

Can the flat surface accept direct paint application?

Yes. The smooth, non-porous surface accepts water-based latex paints and acrylic paints without priming. For dark-to-light color changes, a universal primer improves coverage. Oil-based paints require compatibility testing before full application.

How does the density compare to standard WPC panels?

At 0.6 g/cm³, this panel sits in the mid-density range. Standard decorative WPC panels typically range from 0.5 to 0.55 g/cm³. The increased density improves screw-holding strength and surface flatness for finishing applications.

What installation methods are compatible?

Direct adhesive bonding using polyurethane construction adhesive, screw fixing with countersunk heads, or Z-clip mechanical hanging systems. For adhesive installation, substrate must be flat within 2 mm per meter.

Is the panel suitable for wet area installations?

Yes. Water absorption below 0.5 percent and closed-cell structure prevent moisture ingress. For shower surrounds, seal panel edges and joints with neutral-cure silicone to prevent water wicking into substrate.
