Oxidized Bitumen 75/35 is designed for applications where both moderate flexibility and thermal resistance are required. This balance makes it one of the most practical grades for industries that need performance without excessive rigidity.
As a Turkey based manufacturer and supplier, Basekim delivers this grade with stable quality, optimized for export markets and industrial use.
Why 75/35 is a Smart Choice?
Unlike harder grades like 85/25 or 90/15, this product offers:
- Better flexibility in moderate climates
- Strong adhesion to different surfaces
- Resistance against water and environmental conditions
- Easier handling and application in various industries
This makes it ideal for projects where materials must perform under both movement and temperature variation.
