Natural Wood Fiber

Introduction to Natural Wood Fiber

Natural Wood Fiber is an eco-friendly, versatile, and renewable material derived from wood. It is produced by mechanically or chemically breaking down wood into fine Fibers that can be processed into various products. Known for its sustainability and biodegradability, natural wood fiber is widely used in industries such as construction, textiles, composites, packaging, and automotive manufacturing.

With growing awareness of environmental issues, companies and consumers are increasingly turning to natural wood fiber as a sustainable alternative to synthetic materials. It not only offers durability and high-performance characteristics but also reduces the environmental footprint compared to petroleum-based products.

In this article, we will explore natural wood fiber in detail: its parameters, characteristics, advantages, application scenarios, usage instructions, and frequently asked questions.

Technical Parameters of Natural Wood Fiber

The physical and chemical parameters of natural wood fiber vary depending on the source wood species and processing method. Below are some general specifications:

• Fiber Source: Softwood, hardwood, recycled wood

• Fiber Length: 0.8 – 4.5 mm (softwood fibers are usually longer, hardwood shorter)

• Fiber Diameter: 10 – 30 microns

• Bulk Density: 40 – 120 kg/m³ (depending on processing)

• Moisture Content: Typically 8% – 12% (adjustable depending on application)

• pH Value: 4.5 – 6.5 (slightly acidic to neutral)

• Tensile Strength: 250 – 400 MPa (varies with processing)

• Thermal Conductivity: 0.038 – 0.045 W/m·K (used in insulation)

• Biodegradability: 100% under natural conditions

• Color: Natural light brown to beige

These parameters make natural wood fiber suitable for industrial processing, reinforcement applications, and eco-friendly product manufacturing.
