What is marine plywood and what are its performance requirements?

Marine plywood, also known as ocean board or water-proof plywood, is a subcategory of plywood. The performance requirements of marine plywood mainly include the following points:
– Moisture-proof and water-proof: Marine plywood is mainly used in offshore environments such as ships, docks, containers, and offshore drilling platforms, which requires high moisture-proof and water-proof capabilities of the board.
– High strength: It requires the use of high-strength rotary veneer, with the surface and back panels impregnated with alcohol-soluble phenolic resin, and all core boards (including long core boards) coated with water-soluble phenolic resin, hot-pressed and glued under high unit pressure.
– High environmental protection: The environmental protection level of marine plywood is mainly E0 and E1, and the raw materials are mostly birch, and some are eucalyptus, pine, poplar, etc.
– High temperature resistance: It is required that the finished product can withstand 72 hours of boiling without glue opening.

Marine plywood is added with waterproof glue during production, and is generally used for yachts, car boxes, ships, outdoor wooden buildings, also known as “waterproof plywood”.
