Dadi Black Film Faced Plywood

Product Introduction

Black Film Faced Plywood is a specially designed multi-layer plywood. It has a high-quality black film on the surface. The film gives the board a deep black look. It also greatly improves its weather resistance, wear resistance and water resistance. The plywood is made of high-quality wood materials and compressed at high temperature. This ensures the stability and durability of the structure.

Product Advantages

Exceptional Physical Strength and Deformation Resistance
Black Film Faced Plywood employs high-density timber (such as poplar, birch, or hardwood composite core materials) combined with phenol-formaldehyde resin glue (WBP grade) lamination, achieving a density range of 550-650 kg/m³. It boasts a bending strength (MOR) exceeding 30 MPa and an elastic modulus (MOE) surpassing 6000 MPa. Its multi-layer cross-grained structure (typically over 13 layers) effectively distributes external stress, minimizing cracking risks and enduring lateral pressures of up to 35 kN/m² during concrete pouring, far exceeding the 15 kN/m² load limit of ordinary plywood.

Universal Waterproofing and Corrosion Resistance
The surface is covered with a black phenolic film (0.3-0.5 mm thick), bonded to the substrate through high temperature and pressure, forming a seamless barrier with a water absorption rate below 5% (while ordinary plywood reaches above 12%). It maintains structural integrity after a 48-hour boiling test. The use of WBP (water-boiling proof) adhesive in the core further prevents moisture infiltration, ensuring no delamination or mold growth in extreme temperature and humidity environments ranging from -20°C to 80°C, thereby extending service life by 3-5 times.

High Temperature Resistance and Chemical Resistance
The phenolic film layer can withstand temperatures of 120°C and remains unsoftened or unpeeled even when briefly exposed to 150°C concrete pouring environments. Its acid and alkali resistance (non-corrosive within a pH range of 3-11) accommodates common construction site chemicals like cement slurry and additives. The surface wear rate is only 0.05 mm per cycle, with reusable cycles reaching 20-30 times (while ordinary plywood lasts only 5-8 times).

Precise Dimensional Stability and Processing Compatibility
CNC hot-pressing technology controls thickness tolerance (±0.3-0.5 mm) and flatness error (≤0.1 mm/m²), meeting high-precision formwork splicing requirements. Standard dimensions of 1220×2440 mm support customized cutting, fitting over 90% of construction formwork systems and reducing on-site processing waste (increasing material utilization by 15%).

FAQs

1. How to store Black Film Faced Plywood properly?

To ensure the longevity of Black Film Faced Plywood, store it in a cool and dry place away from direct sunlight. Stack the plywood flat and evenly, with no more than ten sheets in a stack to avoid warping. Also, make sure there is good ventilation to prevent moisture buildup.

2. Can Black Film Faced Plywood be used for outdoor construction?

Yes, Black Film Faced Plywood is suitable for outdoor construction. Its black film surface provides excellent UV resistance, protecting the plywood from sun damage and moisture. However, for prolonged outdoor use, it's recommended to apply a proper sealant or paint to enhance its durability.

3. What should I do if Black Film Faced Plywood gets wet?

If Black Film Faced Plywood gets wet, wipe off any standing water as soon as possible. Allow it to dry naturally in a well-ventilated area. Do not use heat sources to speed up the drying process as it may cause warping. After drying, check for any signs of damage or swelling.

4. How to cut Black Film Faced Plywood for specific project needs?

Use a sharp circular saw or jigsaw to cut Black Film Faced Plywood according to your project requirements. Ensure the blade is appropriate for plywood to get a smooth cut. Mark the cutting lines clearly before starting. Always wear safety gear like goggles and gloves during cutting.

5. Is Black Film Faced Plywood easy to clean after use?

Yes, Black Film Faced Plywood is easy to clean. For everyday dirt and dust, a soft brush or a damp cloth is sufficient. For stubborn stains, a mild detergent solution can be used. Avoid using abrasive cleaners as they may damage the black film surface.
