摘要 |
<p>The panel is formed by hot pressing a mat of resin coated wood strands in which expandable graphite particles are incorporated. The panel comprises a core of resin bonded wood strands with opposite sides and a covering layer of resin bonded wood strands on each side of the core. Each covering layer contains from about 1 to 20 percent by weight of expandable dispersed graphite particles, the core being free of expandable graphite. Each covering layer contains about 8 to 10 percent by weight of expandable graphite. The core has a thickness which is 40 to 60 percent of the thickness of the panel.</p> |
