BLOG HOME  >>  BLOG The adhesives and resins used in the production of OSB are critical to the board’s performance characteristics. Different types of resins are used depending on the intended application of the OSB, ranging from non-structural to highly durable, water-resistant types suitable for exterior use. Urea-Formaldehyde Resin: This adhesive is commonly used in non-structural OSB (OSB/1 and OSB/2). Urea-formaldehyde provides good bonding strength but is not resistant to moisture, making it unsuitable for use in environments where the OSB might be exposed to water. Isocyanate-Based Glues (PMDI): Poly-methylene diphenyl diisocyanate (PMDI) is used in the inner layers of structural OSB (OSB/2 and OSB/3). It provides excellent bonding strength and enhances the board’s overall durability. PMDI is also resistant to moisture, which is crucial for OSB used in load-bearing applications. Melamine-Urea-Formaldehyde (MUF) Resin: Used in combination with other resins, MUF is applied to the surface layers of OSB to improve water resistance. This resin is often found in OSB/2 types, where some level of moisture exposure is expected. Phenol Formaldehyde Resin: This is the resin of choice for high-performance structural OSB (OSB/3 and OSB/4). Phenol formaldehyde is highly resistant to moisture and can withstand harsh environmental conditions, making it ideal for OSB used in exterior applications. Each adhesive type has its advantages and limitations, influencing the suitability of the OSB for different applications. The choice of resin not only affects the board’s strength and moisture resistance but also has implications for environmental and health concerns, particularly in relation to formaldehyde emissions. Classification of OSB Types OSB is classified into different types based on its intended use, with each type offering varying levels of strength, moisture resistance, and durability. Understanding these classifications is essential for selecting the right OSB for specific applications. OSB/1: This is a non-structural OSB type used in dry conditions. It is suitable for interior applications such as furniture or packaging but is not designed to bear loads or withstand moisture. OSB/2: Structural OSB for dry conditions, this type is used in load-bearing applications such as wall sheathing and subflooring. OSB/2 can handle some exposure to moisture, but it is not recommended for use in damp environments. OSB/3: This type is designed for structural use in humid conditions. OSB/3 is commonly used in roofing and exterior wall sheathing where moisture resistance is critical. It can be exposed to the elements for limited periods during construction. OSB/4: The most durable and moisture-resistant type, OSB/4 is used in high-performance structural applications. It is suitable for both interior and exterior use, particularly in areas with high humidity or direct exposure to weather. The classification of OSB types helps builders and contractors select the appropriate material based on the specific requirements of their project. It ensures that the OSB used will perform well under the expected conditions, providing long-lasting and reliable structural support.   BlOG Whatsapp Youtube Facebook X-twitter Instagram

Plywood Blog A blog introducing information about Chinese plywood products and markets HOME  >>  BLOG Particle board, commonly referred to as chipboard, is an engineered wood product that has gained popularity due to its cost-effectiveness and versatility. This guide explores the composition, manufacturing process, advantages, and common applications of particle board. 1. Introduction Definition Particle board, also known as chipboard, is an engineered wood product created from wood particles such as wood chips, sawmill shavings, and other wood residues. Overview of Particle Board Developed as an economical alternative to solid wood and plywood, particle board is manufactured by bonding wood particles with synthetic resin or glue under high pressure and heat. 2. Composition and Manufacturing Process Materials Used Particle board is composed of: Wood Chips: Small wood fragmentsSawmill Shavings: Leftover materials from sawmill operationsWood Residues: Other wood by-products Manufacturing Steps Collection: Wood particles are collected and sorted.Bonding: Particles are mixed with synthetic resin or glue.Pressing: The mixture is pressed under high pressure and heat to form boards.Finishing: Boards are trimmed, sanded, and sometimes laminated for additional strength and aesthetics. 3. Advantages of Particle Board Cost-Effectiveness Affordable: Significantly cheaper than solid wood and plywood.Efficient Use of Resources: Utilizes wood waste, reducing material costs. Versatility Customizable: Can be cut and shaped easily.Surface Treatments: Can be laminated, veneered, or painted. Environmental Impact Sustainable: Uses recycled wood materials, reducing deforestation. 4. Common Applications Furniture Cabinets: Widely used in kitchen and bathroom cabinets.Shelving: Ideal for bookshelves and storage units. Construction Flooring: Used as underlayment for carpets and tiles.Walls: Provides a base for paneling and other wall treatments. Decorative Uses Interior Design: Often used in decorative wall panels and furniture accents. 5. Comparisons with Other Wood Products Particle Board vs. Solid WoodCost: Particle board is more affordable.Strength: Solid wood is stronger and more durable.Particle Board vs. PlywoodCost: Particle board is cheaper.Durability: Plywood is more resistant to moisture and warping. 6. Conclusion Summary of Benefits Particle board is a cost-effective, versatile, and environmentally friendly wood product suitable for various applications in furniture and construction. Future Prospects With advancements in manufacturing techniques and materials, the quality and applications of particle board are expected to expand, making it an even more attractive option for consumers and manufacturers alike.

Plywood Blog A blog introducing information about Chinese plywood products and markets HOME  >>  BLOG Oriented strand board (OSB) is an engineered man-made panel made of wood strands in specific orientations. The strands of wood are bonded together with adhesives under pressure and heat. OSB is durable, strong, rigid and defect-free . It’s easy to use OSB which can be sawn, planed, nailed, screwed and painted. OSB is an excellent replacement of equivalent grades of plywood, solid panel or other wood panels. There are 4 types of OSB according to their physical properties. Their moisture-resistant ability is depending on the glue used. OSB/1 : general purpose OSB (interior use in dry conditions) Glue: UF glue (Urea Formaldehyde) Applications: For non-structural usages, packing, furniture, decorating.  OSB/2 : load-bearing OSB (used in dry conditions) Glue: PMDI(Isocyanate) for the core, MUF (Melamine-Urea-Formaldehyde) or PF(Phenol Formaldehyde) glue for the outer plies. Applications: Furniture, decorating, flooring, roofing, wall, signboards, packing, pallets.  OSB/3 : load-bearing OSB (used in humid conditions) Glue: PF glue (Phenol Formaldehyde). Applications: Flooring, roofing, wall sheathing, signboards, packaging.  OSB/4 : heavy-duty load-bearing OSB (used in humid conditions) Glue: PF glue (Phenol Formaldehyde). Applications (Structure panel): Structural components, wall sheathing, flooring & Subfloors, roofing, I-beams.  The density of OSB: The density of common OSB is 650kg/CBM (+/-5%) . But the density varies with the wood species and compress ratio during production. BlOG Whatsapp Youtube Facebook X-twitter Instagram

Plywood Blog A blog introducing information about Chinese plywood products and markets HOME  >>  BLOG If you import plywood from Russia, you may find that the glue for their plywood are FK glue or FSF glue . What are FK glue and FSF glue? In fact, ‘FK’ stands for Water Resistant Glue (it should be Moisture Resistant Glue) , i.e. MR glue . FK glue is urea-formaldehyde resin (carbamide-formaldehyde resin) , which should meet E1 or E2 grade. ‘FK plywood’ means ‘MR plywood’ . FK plywood is interior plywood which can be used for interior decoration, furniture, packing. ‘FSF’ means ‘water proof glue’ ( it should be ‘water boiling proof glue’), i.e. WBP glue . FSF glue should be phenol-formaldehyde resin . ‘FSF plywood’ is exterior plywood (WBP plywood), which can be used for building & construction, flooring, roofing, furniture, shipbuilding. The meaning of FK & FSF: FK – water resistant plywood (Moisture Resistant, MR plywood) FSF – water proof plywood (water boiling proof, WBP plywood) BlOG Whatsapp Youtube Facebook X-twitter Instagram
