Tropical Plywood: A Brief Explanation
Tropical Plywood – This article is about Tropical plywood. In this article we are trying to provide you complete information about Tropical plywood. We have arranged the information in this post to make you understand it easily. We hope that you can understand it well. Please check the information below.
Tropical plywood is made of mixed species of tropical wood. Originally from the Asian region, it is now also manufactured in African and South American countries. Tropical plywood is superior to softwood plywood due to its density, strength, evenness of layers, and high quality. It is usually sold at a premium in many markets if manufactured with high standards. Tropical plywood is widely used in the UK, Japan, United States, Taiwan, Korea, Dubai, and other countries worldwide. It is the preferred choice for construction purposes in many regions due to its low cost. However, many countries’ forests have been over-harvested, including the Philippines, Malaysia and Indonesia, largely due to the demand for plywood production and export.
There are many products of tropical plywood. One of them is Okoume – Tropical Plywood.
Okoume – Tropical plywood is a high quality plywood with Okoume face veneers and Okoume/Tropical Hardwood core veneers, specially manufactured to provide durability end longevity. Its physical characteristics and mechanical properties are very stable.
Performances and applications
The physical properties of selected Okoume and Tropical Hardwood veneers, combined with high standards manufacturing, result in extra durability, suitable for industrial and building applications.
General properties and tolerances (ex factory)
Thickness: 3 4 5 6 8 10 12 15 18 20 22 25 30 35 40 mm (custom thickness availabla upon request)
Standard sizes: 2500 X 1220/1250 mm, 2500 X 1830 mm, 3100 X 1530 mm (custom sizes available upon request)
Squareness: ±0.25% of the length of the diagonal
Moisture content: between 6% and 10%
Density: 550 kg/cbm ±10%
Glue line: Water and waterproof gluing using either Melamine Urea Formaldehyde (MUF).
Face: Okoume face venners, present a solid surface that is free from open defects. Face veneers are free of knots other than occasional sparse “sound pin” knots. The veneers are reasonably free from irregular grain. Face veneers are B/BB and their thickness is between 1.0 mm and 1.5 mm.
Core Veneers: Okoume and Tropical Hardwood core veneers, laid-up alternatively, have the same basic requirements as face veneers, except that small splits may occur, and there is no limit on the number of pin knots or edge joints. Core veneer thickness is between 1.5 mm and 3.0 mm.
Finishing: All boards are sanded on both sides equally.
Performance characteristics and standards compliance
Standards: Meets the requirements of EN 13986:2004+A1.
Bonding quality: Class 3 (EN 314-2)
Durability (humidity): Class 3 – External use as non-structural components (EN 636)
Formaldehyde class: E1
Reaction to fire: class D-s2, d0
