KPI marine plywood is specially treated plywood that is designed to resist rotting in a high moisture environment. It is manufactured with utmost care in the supervision of technical experts with well selected pieces of core and face veneer. Further, the finished plywood is subjected to proper chemical treatment with water-soluble fixed type preservatives under vacuum pressure to ensure protection against wood destroying organism and to make the product Insects, borer, termites and fungi free.
Being highly resistant plywood to changes In weather and atmospheric conditions, marine plywood is used for all types of woodworking in marine and sea going vessels. It also finds good application in air-freight container making. Now-a-days, Instead of using the normal plywood, Marine plywood can be used In kitchens and bathrooms.
