Film face paper, also known as film-faced plywood, is a versatile and widely used building material. It is commonly employed in construction projects, such as concrete formwork, due to its durability, smooth surface finish, and resistance to moisture. As a leading film face paper supplier, I am often asked about the ingredients typically found in film face paper. In this blog post, I will delve into the various components that make up this essential building material.
1. Base Plywood
The foundation of film face paper is the base plywood. Plywood is an engineered wood product made by gluing together multiple layers of thin wood veneers, known as plies. The grains of adjacent plies are usually oriented perpendicular to each other, which enhances the strength and stability of the plywood.
The type of wood used for the base plywood can vary. Common choices include hardwoods like birch, oak, and maple, as well as softwoods such as pine and fir. Hardwood plywood generally offers greater strength and durability, while softwood plywood is often more cost - effective. The quality of the base plywood is crucial as it provides the structural integrity for the film face paper. For example, 7x8 mm Plain MDF Board can be a suitable base material in some applications where a more uniform and smooth base is required.
2. Film Coating
The film coating is what gives film face paper its characteristic smooth surface and many of its performance properties. There are different types of films used in film face paper, including phenolic film and melamine film.
Phenolic Film
Phenolic film is a popular choice for film face paper, especially in heavy - duty construction applications. It is made by impregnating a paper base with phenolic resin and then curing it under heat and pressure. Phenolic film offers excellent resistance to wear, abrasion, and moisture. It can withstand the harsh conditions of concrete pouring and stripping, making it ideal for concrete formwork. The phenolic resin in the film forms a hard, protective layer that prevents the plywood from absorbing water and damage from the concrete.
Melamine Film
Melamine film is another option for film face paper. It is made by impregnating paper with melamine resin. Melamine film provides a smooth and aesthetically pleasing surface. It is often used in applications where a more decorative finish is desired, in addition to the functional requirements. Melamine - coated film face paper can be found in furniture manufacturing and interior decoration projects. The melamine resin gives the film good chemical resistance and scratch resistance.
3. Adhesives
Adhesives play a vital role in the manufacturing of film face paper. They are used to bond the film coating to the base plywood and also to hold the individual plies of the plywood together.
Plywood Adhesives
For the plywood itself, urea - formaldehyde (UF) resin and phenol - formaldehyde (PF) resin are commonly used adhesives. UF resin is relatively inexpensive and easy to work with, but it has lower water resistance compared to PF resin. PF resin, on the other hand, offers excellent water resistance and is suitable for exterior and high - moisture applications.
Film - Plywood Adhesives
To bond the film coating to the base plywood, special adhesives are required. These adhesives need to have good adhesion strength and be able to withstand the processing conditions during the lamination process. They must also be compatible with both the film and the plywood materials. Some advanced adhesives are designed to provide a strong and durable bond even under high - stress conditions, ensuring that the film does not delaminate from the plywood during use.
4. Additives
Additives are sometimes incorporated into film face paper to enhance its performance or to meet specific requirements.
Fire Retardants
In applications where fire safety is a concern, fire retardant additives can be added to the film face paper. These additives work by suppressing the spread of fire and reducing the flammability of the material. They can be added to the film coating, the plywood adhesives, or both. Fire - retardant film face paper is often used in public buildings, such as schools and hospitals, to meet fire safety regulations.
Anti - microbial Agents
Anti - microbial agents can be added to prevent the growth of mold, mildew, and bacteria on the film face paper. This is particularly important in humid environments or in applications where hygiene is a priority. For example, in food processing facilities or healthcare settings, anti - microbial film face paper can help maintain a clean and safe environment.
5. Surface Treatments
Surface treatments can be applied to the film face paper to further improve its performance.
Anti - Slip Treatments
In construction applications where workers need to walk on the film face paper, anti - slip treatments can be applied. These treatments create a textured surface that provides better traction, reducing the risk of slips and falls. Anti - slip film face paper is commonly used on scaffolding platforms and construction walkways.
UV Stabilizers
UV stabilizers can be added to the film coating to protect it from the damaging effects of ultraviolet (UV) radiation. When film face paper is exposed to sunlight for extended periods, UV radiation can cause the film to fade, crack, or lose its adhesion. UV stabilizers help to maintain the appearance and performance of the film face paper over time, especially in outdoor applications.
