Bitumen 105/35 for roofing and membranes. Exported from Dubai.
A more flexible oxidized bitumen with a high softening point and higher penetration. For roofing felts, waterproofing membranes, adhesives and damp-proofing.
Heat resistant, yet more flexible
Bitumen 105/35 is a flexible oxidized bitumen made by blowing air through straight-run bitumen at controlled temperature. The grade name gives the softening point (105°C) and penetration (35 dmm).
Its higher penetration gives better flexibility and workability than the harder oxidized grades, while the softening point still resists flow on roofs and exposed surfaces.
Black Rock Bitumen supplies Bitumen 105/35 from Dubai to manufacturers, contractors and EPC companies across Africa, Asia and the Middle East.
- High softening point
- Higher penetration for better flexibility and workability
- Good adhesion for coating and saturating
- Suited to roofing, membranes and joint sealing
- Consistent quality in every batch
