Finger Joint Core Film Faced Plywood
Finger Joint Core Film Faced Plywood is a specialized type of plywood designed for construction applications, particularly in concrete formwork. It consists of a finger-jointed core (made from small, interlocking wood pieces) laminated with a melamine or phenolic resin-coated film on both surfaces. This construction enhances durability, moisture resistance, and reusability compared to traditional plywood.
Key Features
Core Material
Typically made from poplar, hardwood, or combi-core (mixed wood species) with finger-jointed segments for stability.
01
Surface Film
Coated with black, brown, or colored melamine/ phenolic film for waterproofing and smooth concrete finishes.
02
Glue Type
Uses WBP (Water Boil Proof), melamine, or phenolic resin for strong adhesion and weather resistance .
03
Common Sizes
1220x2440mm, 1250x2500mm, and customizable thicknesses (9–25mm).
04
Advantages
Cost-Effective & Eco-Friendly
Uses recycled or small wood pieces in the finger-jointed core, reducing waste and material costs.
Cheaper than solid wood or full-plywood core alternatives while maintaining structural integrity.
01
High Durability & Reusability
The melamine/ phenolic film provides scratch, moisture, and chemical resistance, allowing 3–5 reuse cycles in concrete formwork.
Superior nail-holding and screw retention compared to bamboo or steel formwork.
02
Lightweight & Easy Handling
30% lighter than steel formwork, making it ideal for high-rise construction and bridges.
Easier to cut, drill, and assemble on-site.
03
Smooth Concrete Finish
The film-faced surface ensures a glossy, defect-free concrete finish, eliminating the need for plastering and saving 30% construction time.
04
Weather & Temperature Resistance
Performs well in winter conditions due to thermal insulation properties.
Resists corrosion and rust, unlike metal formwork.
