General Uses Top
Suggest a correction!Common products:
- Timber, sometimes marketed in mixed tropical hardwood mixes.
- Industrial rosin and pitch derived from the stump and root resin.
- Small volumes of round logs and sawn timber for local and regional markets.
- Extracts used as tanning materials.
Industrial and craft applications:
- Wood chips converted to kraft pulp, generating brown fiber furnish for packaging and unbleached paper. Chemical composition, with a lignin content around 20–30% and holocellulose >70%, supports pulping.
- Rosin is employed in adhesives (rubber compounding, pressure-sensitive tapes), coatings (shellac-like spirit varnishes, certain protective lacquers), and rubber compounding. Rosin contains acidic diterpenes, imparting tack and solvent release; softening point typically 70–80°C (ASTM E28).
Food and beverages (non-medicinal):
- Not reported as a food, beverage ingredient, or food additive in the cited sources.
Colorants and tanning:
- Bark and wood extracts are used as natural brown dyes for protein fibers (wool/silk) and vegetable fibers; color depth depends on mordants (e.g., Fe, Cr, Cu).
- Wood, bark, and leaf extracts are historically used as tanning materials for leather; the tannins are hydrolyzable (gallotannins/ellagitannins), yielding high-quality leathers when properly controlled with pH and salt regimes.
Wood and fiber:
- Wood is relatively dense and durable, suitable for general construction, light structural components, flooring, and furniture. Physical properties reported for related Mitragyna/Uncaria species include modulus of rupture around 80–100 MPa, modulus of elasticity 9–12 GPa, and air-dry density 500–800 kg/m³.
- Sapwood is moderate; heartwood shows natural brown coloration due to extractives.
Fragrance and cosmetics:
- Resin and bark extracts are reported as fragrance materials in flavor and fragrance compounding; safety assessments are included in standard fragrance and cosmetics monographs.
Properties relevant to use:
- Wood composition supports kraft pulping: lignin approximately 20–30%, holocellulose >70%.
- Rosin is acidic (acid number around 100–160 mg KOH/g), typically softening near 70–80°C (ASTM E28), and dissolves in organic solvents used in coatings and adhesives.
- Tannins are hydrolyzable, allowing efficient leather tanning and dyeing in acidic conditions.
Standards and regulation:
- Lumber is traded under the ASEAN Common Classification of Tropical Timber Species (ATIBT) and national timber grading rules.
- Rosin and rosin-derived derivatives comply with ASTM D509 and related grading standards; food-contact applications follow national and international rules; fragrance materials are evaluated in IFRA standards.
Sustainability and sourcing:
- Occurs in South and Southeast Asia; timber is sourced from logged natural forest and plantation thinning. Logging in peat swamp and lowland forest has been reported in specific regions. Conservation status is not reported; monitoring of supply chains and habitat impact is advised.
