WPC vs. HDHMR: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 15, 2024
WPC (Wood Plastic Composite) is a blend of wood fibers and plastic, while HDHMR (High-Density High Moisture Resistance) is an engineered wood product with superior moisture resistance.

Key Differences

WPC, or Wood Plastic Composite, is a hybrid material composed of natural wood fibers and thermoplastic resin. It's known for its durability and resistance to environmental factors. Conversely, HDHMR, standing for High-Density High Moisture Resistance, is an engineered wood product designed for high moisture resistance and durability, primarily used in areas prone to water exposure.
In terms of composition, WPC combines the aesthetics of wood with the durability of plastic, making it suitable for outdoor decking and landscaping. HDHMR, on the other hand, is crafted through a process that infuses fiberboard with resins, elevating its density and moisture resistance, making it ideal for kitchen cabinets and bathroom vanities.
When considering environmental impact, WPC is often praised for utilizing recycled plastics and wood waste, thereby reducing landfill waste. HDHMR, while being an innovative product in the realm of engineered wood, doesn't typically use recycled materials but focuses on performance in damp environments.
Maintenance-wise, WPC is low-maintenance, requiring occasional cleaning without the need for painting or sealing. HDHMR, in contrast, may require more care in terms of protection against scratches and heat, although its moisture resistance minimizes the risk of warping or swelling.
Regarding cost, WPC can be more expensive upfront due to its composite nature, but its durability makes it a cost-effective choice in the long run. HDHMR, while competitively priced, offers exceptional value, particularly for indoor use where moisture resistance is a priority.
