How does WPC’s coefficient of friction influence outdoor sofa cushion stability?

The coefficient of friction (COF) of Wood-Plastic Composite (WPC) plays a critical role in ensuring the stability of outdoor sofa cushions. A higher COF means greater resistance to slipping, which is essential for maintaining cushion placement, especially in windy or high-traffic outdoor environments. WPC’s textured surface and material composition contribute to this friction, reducing the likelihood of cushions sliding off furniture. Additionally, WPC’s durability against moisture and UV exposure ensures long-term friction performance, unlike traditional materials that degrade over time. By optimizing WPC’s COF, manufacturers can enhance user safety and comfort, making it an ideal choice for outdoor furniture applications. Understanding this relationship helps consumers select cushions that combine aesthetics with practicality.
