18mm Construction Laminated Hardwood Birch Beech Eucalyptus Oak Maple Timber Melamine Film Faced Concrete Centring Formwork Shuttering Plywood

1. Material and Composition

• Core Materials
  • It is typically composed of multiple layers of wood veneers, such as poplar, pine, eucalyptus, etc. These woods have different properties. For example, poplar is relatively lightweight and has a relatively low price; pine has high strength and an aesthetically pleasing texture; eucalyptus offers good hardness and water - resistance.
• Film Coating
  • Its most notable feature is the red film coated on one or both sides. This film is generally made of phenolic resin, which endows the plywood with good strength and durability.

2. Properties

• Durability
  • Due to the resin coating on the surface, this type of plywood is highly durable. It can resist water, moisture, chemicals, and abrasion, making it suitable for various harsh environments.
• Moisture Resistance
  • The phenolic resin film forms an effective waterproof barrier, giving the plywood excellent waterproof performance. It reduces the erosion of moisture on the wood, minimizing the risks of deformation, cracking, and decay. Thus, it can be used in humid environments or outdoor areas.
• Strength and Stability
  • The cross - grained structure of the plywood enables it to distribute loads evenly, enhancing its load - bearing capacity. It has high strength and stability, making it suitable for applications with high - strength requirements, such as concrete building formwork.
• Smooth Finish
  • The red film coating results in a smooth and flat surface of the plywood. This not only provides a good visual effect but also facilitates operations like demoulding and cleaning during use. It also benefits subsequent decoration and processing.
