EPiC database - MDF sheet

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.Medium density fibreboard (MDF), is a manufactured timber product made from reconstituted wood fibres. It is denser than particleboard or plywood, and has a smooth finish. MDF is commonly covered with timber veneer, vinyl, or a melamine paper coating, providing increased durability, water resistance and aesthetic qualities. MDF is cost-effective when compared with other sheet materials, and is typically stronger than particleboard. MDF is created by combining residual wood fibres with a resin binder and wax, and pressing at a high temperature. Urea-formaldehyde is commonly used for non-waterproof applications, and melamine urea formaldehyde for increased water resistance. MDF is commonly used for joinery and interior purposes. Depending on the resin used, it can have a moderate resistance to water, and is generally not suited to exterior applications.

本材料系免费环境性能建筑（EPiC）数据库的一部分。该EPiC数据库采用全面混合生命周期清单方法，包含了250多种建筑材料的固有环境流系数。中密度纤维板（MDF）是一种由重组木质纤维制成的工业木材产品，其密度高于颗粒板或胶合板，表面光滑。MDF通常覆盖以木材贴面、乙烯基或三聚氰胺纸质涂层，从而增强其耐用性、防水性能及美学品质。与其它板材材料相比，MDF具有较高的性价比，且通常比颗粒板更为坚固。MDF的生产过程涉及将残余木质纤维与树脂粘合剂及蜡混合，并在高温下压制而成。在非防水应用中，通常使用尿素甲醛树脂，而在增强防水性能时则采用三聚氰胺脲醛树脂。MDF常用于木作和室内装饰，根据所使用的树脂不同，对水的抵抗力可适中，通常不适宜用于室外应用。
