EW16 is a wood plastic composite decking board requiring minimum maintenance. Durable and between the maximum temperature of utilisation once installed, and the outdoor temperature at the time of installing. (cf. Expansion table, Fig. C, and photo 8). . The expansion shrinking coefficient is 3.6 x 10 -5 per degree.

Wood-plastic composite (WPC) deck products are the dominant type, although there are rice husk-plastic and other fillers, as well as entirely plastic versions. Thermal Expansion Coefficient: It is important to understand how much the boards will move, especially under Australian summer conditions.

The successful development of durable wood-plastic composite (WPC) cladding is a challenge for the industry. .. minimum values which ensure that the cladding product at least performs in a particular way which fits to its application, such as dimensional accuracy or maximal thermal linear expansion.

Solution. Formtech recommended a Wood Plastic Composite material, which had a lower CTE and higher HDT than plastic resins. This meant that the material could withstand temperature changes and hot environments better than other materials, including PVC. This material also looked like wood, which was an added

This may explain why most of the extruded plastics or WPC boards produced have been used for deck and boardwalk surfaces, where flexibility is less important. However ASTM D 6341-98, Linear Coefficient of Thermal Expansion of Plastic Lumber and Plastic Lumber Shapes between [ 34.3 and 60 C] 30 and 140 F.

Wood-Plastic Composite Deck Boards and Guardrail Systems (Guards or Handrails). 3. ASTM D 2017: ASTM D 2394: Standard Test Methods for Simulated Service Testing of Wood and. Wood-Base Finish Thermal expansion coefficient: 2.0 x 10¯5 in in °F (3.6x10¯5 cm cm °C);. ASTM D1037 g.

in the early 1990s as weather-resistant decking. The product concept has evolved rapidly into railing, fencing, trim, automotive parts, and other applications. Adding wood to plastic to make WPC reduces the formula cost, raises the modulus of elasticity, and lowers the coefficient of thermal expansion.

With its hard surface, Wear resistance and significant friction, LunaComp Deck is ideal in hotels, restaurants, around pools and marinas and of course, in your home. LunaComp Deck feels comfortable under bare feet but, unlike solid wood decks you need not.
