The phenolic film used in birch brown film faced plywood
The phenolic film used in brown film faced plywood is a synthetic material that is applied to the surfaces of the plywood panels. It is made by impregnating layers of kraft paper with phenolic resin and then bonding them together under high pressure and heat.
Brown film faced plywood information
Phenolic resin is a type of thermosetting plastic that is known for its excellent mechanical and chemical properties. It is highly resistant to moisture, chemicals, abrasion, and wear, making it an ideal choice for applications where plywood needs protection from these factors.
The phenolic film used in brown film faced plywood is typically around 120-220 grams per square meter (gsm) in weight. The film is usually dark brown or black in color, although other colors may be available depending on the manufacturer. The film is usually smooth and has a glossy or matte finish, depending on the desired aesthetic.
The film is applied to both sides of the birch plywood panel using a hot-press process. The heat and pressure during the manufacturing process cause the phenolic resin to bond with the plywood, creating a strong and durable composite material.
The phenolic film provides several benefits to the birch plywood. It acts as a protective barrier, preventing moisture from penetrating the plywood and causing warping or delamination. It also protects the plywood from chemicals, such as those found in concrete or other construction materials.
Additionally, the film enhances the smoothness of the plywood surface, making it easier to clean and maintain. It also provides a consistent and even surface finish, which is important for applications such as concrete formwork or furniture manufacturing.
Overall, the phenolic film used in birch brown film faced plywood adds durability, moisture resistance, and a smooth surface to the plywood panels, making them suitable for a wide range of applications in construction, furniture, packaging, and other industries.
