Medium-Density Fibreboard (MDF) or Particle Board
Non-botanical (Engineered Wood Product) • Engineered
Grain Pattern
No natural grain; features a uniform, non-directional composite texture with visible wood fibers or particles compressed together
Color Description
Tan to light brown heartwood-like hue throughout; uniform color without sapwood distinction; dull matte luster; may darken slightly with UV exposure
Hardness Rating
700-1000 lbf (Soft to Medium); vary based on density/resin content
Durability Rating
Non-durable; very low resistance to rot and moisture; prone to swelling/crumbling when wet; susceptible to fungal decay
Common Uses
Cabinetry carcases, inexpensive furniture, underlayment, shelving, moldings, and substrate for veneers or laminates
Geographic Origin
Global (manufactured worldwide using various softwood/hardwood residuals)
Market Value & Sustainability
Estimated Market Value
0.50 - 1.50 USD per board foot equivalent (typically sold by the sheet)
Wood Age Estimate
Contemporary (likely manufactured within the last 10-20 years based on surface texture and color preservation)
Sustainability Status
Generally sustainable; utilizes recycled mill waste and wood residuals; formaldehyde-free versions available; FSC certified products common
Workability
Excellent for sawing and routing; edges are porous and require sealing; creates fine, hazardous dust; does not hold screws as well as solid wood in the edges
Notable Features
Uniform density; isotropic properties; faint chemical or resins odor; dust can be an irritant/carcinogen (formaldehyde resins)
Finish Recommendations
Requires primer/sealer to prevent excessive absorption; lacquer, oil-based paint, or wood veneer laminates are recommended
Identification Confidence
High; the visible surface shows characteristic compressed fibers and lack of cellular grain structure unique to composite engineered boards
