Oxidized
Bitumen 105/35
Petra Oil’s Oxidized Bitumen 105/35 is a premium-grade, semi-hard oxidized bitumen formulated for applications where enhanced flexibility and moderate thermal performance are needed. With a softening point of approximately 105°C and a penetration of 35 dmm at 25°C, Bitumen 105/35 strikes a practical balance between hardness and elasticity, making it ideal for environments with moderate temperature variations.
This grade is created by blowing hot air through pure bitumen, modifying its chemical structure to improve performance in roofing, sealing, flooring, and anti-corrosion treatments. Bitumen 105/35 offers dependable performance in damp and humid conditions and is frequently used in damp-proofing, bridge deck protection, and as an additive in bituminous mastics and adhesives. Produced in accordance with ASTM standards, Bitumen 105/35 is known for its consistency, reliable bonding characteristics, and long shelf life.
