What is marine plywood?

Marine plywood is manufactured from durable face and core veneers, with few defects so it performs longer in both humid and wet conditions and resists delaminating and fungal attack.

It mainly use poplar, eucalyptus, okoume, hardwood, paulownia wood,to make marine plywood. Firstly, make wood to veneer. Second, make glue on veneers. Third, laminate veneer together. Four, cold press the board for several hours. Five, glue it face and back again. Six, Laminate face and back veneer on board. Seven, cold press again. Eight, hot press the board. Nine, cut four side to make the board smooth. The plywood is finished.

Its construction is such that it can be used in environments where it is exposed to moisture for long periods. Each wood veneer will be from tropical hardwoods, have negligible core gap, limiting the chance of trapping water in the plywood and hence providing a solid and stable glue bond. It uses an exterior Water and Boil Proof (WBP) glue or phenolic glue similar to most exterior plywood.This kind plywood has high requirements of waterproof. Because the plywood is used at high moisture grade environment.Like boat building, Surfboard, the house near to river or building on the river.

Marine plywood can be graded as being compliant with BS 1088, which is a British Standard for marine plywood. There are few international standards for grading marine plywood and most of the standards are voluntary. Some marine plywood has a Lloyd's of London stamp that certifies it to be BS 1088 compliant. Some plywood is also labeled based on the wood used to manufacture it. Examples of this are Okoume or Hardwood. Because the high requirements of waterproof and quality. The veneer of material will be whole big piece veneer to make it. The usage has high requirements of the quality.The glue and quality has to be matched with the Standard of BS1088 Certification.
