Product Overview

The Industry Standard for Reliable Construction and High-Volume Casting

Black Film Faced Plywood is the workhorse of the modern construction site. Engineered for versatility and cost-efficiency, this panel features a high-density birch or hardwood combi-core that provides the structural rigidity necessary for vertical and horizontal concrete molding. The surface is overlaid with a sleek, black phenolic film (typically 120g/m²) that is bonded under high heat to create a hard, moisture-resistant shell. This film not only protects the wood from the alkaline nature of wet concrete but also ensures a smooth, clean release, allowing for a professional finish on structural walls, foundations, and slabs. It is the go-to solution for contractors who require a balance between high performance and competitive pricing.

The core strength of our Black Film Faced Plywood lies in its WBP (Water Boil Proof) phenolic glue lines. This adhesive technology ensures that the veneers remain tightly bonded even in the most punishing weather conditions, preventing delamination during the hydration process of the concrete. To further enhance durability, the edges of every sheet are treated with a specialized waterproof acrylic sealant. This critical step prevents moisture wicking, which is the primary cause of edge swelling. By maintaining the panel's dimensional stability, we ensure that it can be reused across multiple cycles, providing a lower "cost-per-pour" for large-scale infrastructure and residential projects alike.

In addition to its primary use in formwork, the black phenolic surface is highly valued for its utilitarian aesthetics. It is frequently used in the construction of temporary hoarding, workshop storage, and utility trailers. The black finish is non-porous and easy to wipe down, resisting oils, fuels, and common construction chemicals. Whether it is used to cast a smooth basement wall or to build a rugged temporary platform, this panel delivers a consistent, high-quality result that professional builders have relied on for decades.

Precision is at the heart of our manufacturing. Each panel is calibrated to ensure uniform thickness, allowing for seamless alignment in large formwork systems. This consistency reduces the need for "grinding" concrete joints after the forms are stripped, saving significant labor time on the job site. With a focus on structural integrity and surface reliability, our Black Film Faced Concrete Formwork is an essential component for any modern building project.

Logistics and Financial Terms

Formwork panels are shipped in high-volume industrial pallets. We utilize moisture-proof shrink wrapping and heavy-duty steel strapping to ensure the panels remain flat and protected from sea air during international transit. Payment terms are typically 30% T/T deposit with the balance against B/L. We provide structural certificates and test reports to meet site safety requirements.

Performance Comparison

  • Vs. Brown Film Plywood: Black film is the most cost-effective for standard projects; Brown film is typically used for higher reuse requirements.
  • Vs. Raw Plywood: The phenolic film prevents water absorption and allows for much easier concrete release.
  • Vs. Steel Forms: Plywood is lighter, easier to cut on-site, and significantly more affordable for mid-scale projects.

Structural Composition

The Phenolic Film is a paper sheet impregnated with resin, fused to the wood core under high pressure.

The WBP Glue creates a chemical bond between the cross-laminated veneers that is stronger than the wood itself, ensuring the panel does not split even when submerged in water for long periods.

Green Building Commitment

By providing a board designed for multiple reuse cycles (up to 15-20 times for premium cores), we help reduce the total volume of timber consumed on construction sites. Our panels are available with FSC certification to ensure responsible forest management, and we utilize low-emission adhesives to minimize environmental impact during production.

Frequently Asked Questions
Q: How many times can I reuse it?
A: A poplar core allows 5-8 reuses; a combi core 8-12; and a full birch core can exceed 20 reuses with proper care.
Q: Does the film peel off?
A: No, the film is thermally fused into the wood fibers, making it inseparable under normal working conditions.
Q: Can I cut the board?
A: Yes, but you must reseal the cut edges with waterproof paint to prevent swelling.
Q: Is it 100% waterproof?
A: The surface and WBP glue are waterproof, but edges are the vulnerable point; keep them sealed for best results.
Q: What thickness is best for floor slabs?
A: 18mm is the standard for most slab and wall formwork systems.
Q: Do I need release oil?
A: Yes, applying a light coat of release oil before each pour extends the life of the film and improves the concrete finish.
Q: What is "Combi Core"?
A: It is a core made of alternating layers of birch and poplar, balancing the strength of hardwood with the economy of softwood.
Q: Can it be used for furniture?
A: Yes, its industrial look is popular for workshop shelving and rugged utility furniture.
Q: How do I store the panels?
A: Store them flat in a dry, shaded area to prevent warping and UV damage to the film.
Q: Does it produce a "mirror" concrete finish?
A: It produces a smooth, matte-to-semi-gloss finish that is much cleaner than raw timber forms.
