Introduction
Finger joint core film faced plywood is a resilient and eco-friendly construction material specifically designed for concrete formwork applications. It features a cross-laminated construction and utilizes recycled core materials, making it a sustainable choice. This plywood is bonded together with phenol formaldehyde resin and overlaid with a hard, durable resin impregnated paper to achieve a smooth concrete finish. Known for its high density and strength, finger joint core film faced plywood is commonly available with black or brown film finishes. In this article, we will explore the specifications and characteristics of finger joint core film faced plywood, including its finish options, glue type, sheet dimensions, thickness range, density, and edge profile.

1. Finish: Phenolic Film in Various Colors Finger joint core film faced plywood is available with a phenolic film finish, which provides excellent protection and durability. The film comes in various colors, including black, brown, red, and green, allowing for design versatility. The phenolic film ensures a smooth surface, ease of demolding, and resistance to moisture, making it ideal for achieving high-quality concrete finishes.
2. Glue: Phenolic Resin WBP Finger joint core film faced plywood is manufactured using phenolic resin WBP (Water Boil Proof) glue. This glue type offers exceptional water resistance, ensuring that the plywood can withstand exposure to moisture, both during construction and in the final structure. The phenolic resin WBP glue provides strong bonding strength, enhancing the structural integrity of the plywood in demanding formwork applications.
3. Sheet Dimensions: Standard Size for Versatile Applications Finger joint core film faced plywood typically comes in a standard sheet dimension of 1220mm x 2440mm. This size provides versatility and compatibility with various construction frameworks and formwork systems, ensuring easy installation and efficient utilization of the plywood.
4. Thickness Range: Tailored to Project Requirements Finger joint core film faced plywood is available in various thickness options to cater to specific project needs. Common thicknesses include 6mm, 9mm, 12mm, 15mm, 17mm, 18mm, 21mm, and 25mm. The range of thicknesses allows for flexibility in meeting structural and load-bearing requirements, ensuring reliable performance in concrete formwork applications.
5. Density: 520-550kgs/CBM Finger joint core film faced plywood exhibits high density, typically ranging from 520 to 550 kilograms per cubic meter (kgs/CBM). This high-density composition contributes to the plywood’s strength, stability, and resistance to warping or deformation. The density ensures that the plywood can withstand the demanding conditions of concrete formwork, providing a reliable and durable solution.
6. Edge Profile: Square Edged with Water Repellent Edge Sealant Finger joint core film faced plywood comes with square edges, providing a clean and precise appearance when installed. Additionally, it features a water repellent edge sealant, which enhances the plywood’s moisture resistance and prevents water penetration through the edges. This feature adds to the longevity and performance of the plywood in varying weather conditions.

Conclusion
Finger joint core film faced plywood is a resilient and sustainable choice for achieving smooth concrete finishes in formwork applications. Its cross-laminated construction, utilization of recycled core materials, and phenolic film finish offer durability, moisture resistance, and ease of demolding. With phenolic resin WBP glue, the plywood ensures excellent water resistance and strong bonding strength. Standard sheet dimensions and a range of thicknesses allow for versatility in different construction projects. The high density of finger joint core film faced plywood provides strength and stability. Equipped with square edges and water repellent edge sealant, it ensures durability and moisture protection. When it comes to concrete formwork, finger joint core film faced plywood proves to be a reliable and sustainable choice, offering the strength and performance required for successful construction projects
