Dimensional Stability & Flatness - Performance Panels

plywood and wood expand upon heating, as do practically all known solids. The thermal expansion of wood, however, is quite small and requires exacting techniques for its measurement. The effect of temperature on plywood dimensions is related to the percentage of panel thickness in plies having grain perpendicular to the direction of expansion or contraction. The average coefficient of linear thermal expansion is about 3.4 x 10<sup>-6</sup> inch/inch per degree F for a plywood panel with 60&nbsp; 【Get Price】

Dimensional change – calculate expansion of bamboo

Dimensional change – calculate expansion of bamboo Dimensional change coefficient. Bamboo has a tangential dimensional change coefficient (the amount the fibers will expand or contract) of 0.00144. Moisture content (MC). Moisture content for flooring installations varies between 4% and 18%. The moisture content required depends on the Bamboo plywood is a lot more stable than a solid plank; it does not expand and contract as much as solid wood. Here are a few tips to&nbsp; 【Get Price】

Facts About Plywood and LVL - Engineered Wood Products

The thermal expansion of plywood is quite small. The average co-efficient of thermal expansion of plywood is 4.5 x 10-6 mm/mm/oC. thermal Conductivity. The ability of a material to conduct heat is measured by its thermal conductivity, k. The higher the k value, the greater the ability of the material to conduct heat. The lower the k, the higher the insulation value. thermal conductivity varies with timber species, however an average value of k=0.1154 W.m/(m2 °C) for softwood timbers is&nbsp; 【Get Price】
