25*25mm Wood Grain Wood-Plastic Composite Right-Angle Moulding

Key Advantages

• Wood grain fidelity: Printing resolution ≥300 dpi with ≥16 grayscale levels for natural grain transitions. Texture depth 0.2–0.4mm provides visual and tactile characteristics similar to natural oak or walnut.
• Dimensional stability: Linear expansion coefficient ≤3.0×10⁻⁵/℃. Under cyclic temperature (-10°C to 40°C) and humidity variation, lengthwise dimensional change ≤0.5mm/m.
• Weathering resistance: Per GB/T 16422.2 Xenon arc test (500 hours), color difference ΔE ≤3, gloss retention ≥80%. Suitable for semi-outdoor environments (covered balconies, porches).
• Water and corrosion resistance: 24-hour water absorption ≤1.2%. Salt spray resistance ≥168 hours (5% NaCl, 35°C) without corrosion.
• Low maintenance: Surface hardness ≥2H (pencil hardness). Abrasion resistance ≥5,000 wet wipe cycles without visible wear.

Product Specifications

Application Scenarios

• Interior wall corner protection (living rooms, bedrooms, hallways)
• Feature wall corner finishing (stone veneer, wood panels, upholstered panels)
• Integrated wall panel system trim (top of baseboard, vertical panel corners)
• Commercial space wall finishing (boutique hotels, tea houses, resorts)
• Semi-outdoor wall and column wrapping (enclosed balconies, entry porches)
• Covering existing damaged corners in renovation projects

Frequently Asked Questions and Precautions

Q: Will the wood grain pattern fade over time?
A: Under normal indoor lighting (illuminance ≤500 lux, no direct sunlight), heat-transferred wood grain maintains appearance for 5–8 years without significant fading. For semi-outdoor applications, co-extruded wood grain layers (thickness ≥0.3mm) provide more stable UV resistance.

Q: Can this product be used in rooms with in-floor radiant heating?
A: Yes. WPC thermal conductivity ranges from 0.25–0.35 W/(m·K), minimally affecting radiant heat output. Provide an expansion gap of 3–5mm between the moulding and flooring, filled with flexible sealant.

Q: How to address color variation after installation?
A: Color difference ΔE ≤1.5 Within the same batch, and ≤2.5 Between different batches. Pre-sort and dry-fit before installation. Use noticeably different pieces on non-continuous surfaces (e.G., Separate columns or different walls).

Q: Can 45° miter joints be made?
A: Yes. Use a miter saw with a 45° setting. Apply matching color edge wax or touch-up pen to cut ends. Ensure both pieces are aligned within the same plane with deviation ≤0.5mm.

Precautions

• Substrate moisture content must be ≤12% (measured with moisture meter) before installation. Higher moisture may cause adhesive failure or mold growth behind the moulding.
• Wear a dust mask during cutting. Wood-plastic composite dust is mildly irritating. Use tungsten carbide saw blades (≥80 teeth) for clean cuts.
• For humid environments (bathroom dry areas, balconies), apply mold-resistant neutral sealant to the back and ends of the moulding.
• Avoid cleaning with strong solvents such as acetone, toluene, or mineral spirits, which may damage the heat transfer layer. Use neutral cleaners (pH 6.5–7.5) With a soft cloth.
• Store horizontally on dry, flat ground away from direct sunlight and high temperatures (>50°C). Stack height ≤1.2M with soft separators between layers.
