Technical Specifications & Features | Bitumen 35/50
Product Nature: A 100% pure petroleum-based product, high-quality and refined.
Production Process: Manufactured from vacuum bottom residues through a controlled hot air blowing process.
Penetration Grade: Features a standard penetration range of 35 to 50 dmm (desi-millimeter) at 25°C.
Softening Point: Exhibits a thermal softening point stabilized between 50°C and 58°C.
Physical Behavior: Possesses excellent thermoplastic properties—behaving similarly to synthetic resins by softening when heated and hardening upon cooling.
