Papuan Bintangor
Scientific name: Calophyllum papuanum
Overview
Papuan Bintangor (Calophyllum papuanum) is a tropical hardwood native to New Guinea and surrounding islands of the southwestern Pacific. A member of the Calophyllaceae family, it is one of several commercially important species marketed under the general trade name Bintangor. The species grows naturally in lowland tropical rainforests, where it develops large, straight trunks capable of producing high-quality commercial timber.
The wood is valued for its attractive appearance, moderate density, and dependable working characteristics. Throughout Papua New Guinea and neighboring regions, Papuan Bintangor has long been used for furniture, cabinetry, veneer, paneling, interior joinery, and general construction. Although it is less familiar internationally than Teak or Mahogany, it remains an important regional hardwood because of its versatility and ease of machining.
Freshly cut heartwood ranges from pale golden-brown to medium brown before gradually deepening in color with age. The grain is generally interlocked or gently wavy, producing attractive ribbon figure on quartersawn lumber. Combined with its moderate natural luster, these characteristics make Papuan Bintangor suitable for both decorative and structural woodworking applications.
Within the Asian hardwood collection, Papuan Bintangor represents one of the important Pacific members of the Calophyllum genus and contributes to the diversity of the Bintangor timber group.
Quick Facts
- Common Name: Papuan Bintangor
- Scientific Name: Calophyllum papuanum
- Region: Asian Hardwoods
- Native Range: Papua New Guinea, Indonesian New Guinea
- Tree Size: 90–150 ft tall (27–46 m), 2–5 ft trunk diameter (0.6–1.5 m)
- Average Dried Weight: Approximately 40–47 lbs/ft³ (640–755 kg/m³)
- Janka Hardness: Approximately 1,350–1,600 lbf
- Color: Golden brown to medium brown, darkening gradually with age
- Grain: Usually interlocked to slightly wavy

Identification Characteristics
Papuan Bintangor is recognized by its attractive golden-brown heartwood, medium texture, and interlocked grain. The sapwood is pale cream to light yellow and is clearly distinguished from the darker heartwood.
The wood possesses moderate natural luster and commonly develops ribbon figure on quartersawn lumber because of its interlocked grain. Medium-sized pores and a relatively uniform texture contribute to smooth finished surfaces and attractive appearance.
Key identification traits include:
- Golden-brown heartwood
- Cream to pale yellow sapwood
- Interlocked to slightly wavy grain
- Medium texture
- Moderate natural luster
- Ribbon figure on quartersawn lumber
- Distinct heartwood and sapwood contrast
- Good natural durability
Working Properties
Papuan Bintangor is considered an easy-to-machine hardwood that performs well with both hand and power tools. While interlocked grain may occasionally produce minor tear-out during planing, sharp cutters generally provide smooth finished surfaces.
The wood glues readily, sands well, and accepts both stains and clear finishes evenly. It also turns well and develops an attractive natural polish suitable for fine woodworking and architectural applications.
- Machines well
- Turns well
- Sands smoothly
- Accepts glue readily
- Finishes exceptionally well
- Develops an attractive natural polish
- Moderate dimensional stability
- Occasional tear-out in interlocked grain
Safety Note
Wood dust from Papuan Bintangor may cause skin, eye, or respiratory irritation in sensitive individuals. Proper dust extraction and respiratory protection are recommended during machining and sanding operations.
Common Uses
Papuan Bintangor common uses include:
- Fine furniture
- Cabinetry
- Interior millwork
- Architectural trim
- Decorative veneer
- Paneling
- Flooring
- Woodturning
- Boat interiors
- Carvings
- General construction
- Collector wood samples
Sustainability & Notes
Calophyllum papuanum grows within the tropical rainforests of New Guinea, one of the world’s richest regions for biodiversity. These forests support countless plant and animal species while also providing valuable timber resources that contribute to regional economies.
As with many tropical hardwoods, sustainable forest management and responsible harvesting practices are essential to maintaining healthy forest ecosystems. Certified forestry programs and responsible sourcing help ensure that Papuan Bintangor remains available while protecting the extraordinary biodiversity of New Guinea’s rainforests.
