Product type
Wood pulp is a fibrous material derived from wood that serves as the primary raw material in the production of paper and other cellulose-based products. It is obtained through processes such as mechanical pulping, chemical pulping, or semi-chemical pulping, which break down the wood fibers while preserving their strength and integrity. Wood pulp is typically used in the manufacture of various paper products, including newsprint, cardboard, and tissue paper.
| Types | Mechanical, chemical, and semi-chemical |
| Fiber length | 0.5 to 5 mm |
| Moisture content | Up to 10% |
| Brightness | 30% to 90% ISO |
| Viscosity | 300 to 800 mPa·s |
When selecting wood pulp, buyers should consider the type of pulp required for their specific application, such as mechanical or chemical pulp. It's important to specify the desired fiber length, moisture content, and brightness level to ensure the pulp meets production standards. Additionally, buyers should inquire about certifications related to sustainability and environmental impact, as well as the quantities needed for their projects.
