Bitumen 75/35: Dynamic Grade for Flexible Industrial

Bitumen 75/35 Dynamic Solution for Precision in Industrial Applications

When industrial projects require the perfect balance between flexibility and strength, Bitumen 75/35 delivers performance you can count on. This specialized oxidized bitumen grade is engineered for professionals who demand consistency, weather-resistance, and ease of application. Bitumen 75/35 is recognized for its moderate softening point and tailored penetration value, offering exceptional results in sealing, insulation, and protective coatings across a wide variety of industries.

Key Technical Properties of Bitumen 75/35

Bitumen 75/35 is manufactured using a precise oxidation process that transforms premium base bitumen into a stable, semi-flexible compound. This unique grade is defined by a softening point of 75°C and a penetration value of 35 dmm, delivering a product that is neither too hard nor too soft—ideal for applications where adaptability is essential.

Notable Technical Properties:

• Optimized Softening Point (75°C): Maintains shape and structure under moderate to high temperatures, minimizing risk of deformation in warm climates.

• Balanced Penetration (35 dmm): Offers a compromise between rigidity and flexibility, making it easy to work with while ensuring reliable durability.

• Excellent Water and Vapor Resistance: Provides long-lasting protection against moisture intrusion, essential for both above-ground and sub-surface uses.

• High Adhesion: Adheres strongly to diverse surfaces, including concrete, metal, and building materials.

• Consistent Chemical Resistance: Withstands exposure to industrial chemicals, alkalis, and mild acids, prolonging service life in aggressive environments.

• Enhanced Workability: The unique blend of strength and pliability allows for smoother application in construction and manufacturing settings.

Industrial Applications of Bitumen 75/35

The balanced formulation of 75/35 supports a diverse range of industrial sectors, making it the material of choice for challenging and technical environments.

• Protective Coatings: Used on pipelines, tanks, and metal structures to prevent corrosion, even in chemically aggressive or moisture-prone locations.

• Roofing Systems: Essential in multi-layer waterproofing membranes and felts,  75/35 provides both elasticity and stability—ideal for roofs exposed to thermal cycling.

• Joint Sealants: Perfect for expansion joints in roads, bridges, and industrial floors where movement and vibration are frequent, yet a watertight seal is required.

• Damp-Proofing: Utilized in foundation walls and basement slabs to block water ingress and reduce the risk of mold or structural damage.

• Electrical Insulation: Its composition and flexibility make it suitable for cable sheathing and battery sealing, maintaining electrical integrity under various conditions.

• Industrial Mastics and Adhesives: The workability and strong bond of 75/35 enhance the performance of mastics, tile adhesives, and protective linings.

Manufacturing Process: How Bitumen 75/35 Is Made

Producing  75/35 involves a highly controlled air-blowing process to ensure every batch meets strict performance requirements:

1. Feedstock Selection: Carefully chosen penetration grade bitumen is tested for consistency and purity.

2. Heating: The base bitumen is gradually heated in closed reactors to a precise temperature range (230–260°C).

3. Air Oxidation: Dry air is passed through the heated bitumen, adjusting the chemical structure to achieve the targeted softening point and penetration values.

4. Real-Time Quality Control: Lab analysis ensures each batch matches  75/35’s specification for hardness, flow, and adhesion.

5. Finishing and Cooling: The finished product is cooled and prepared for immediate packing to preserve quality during storage and shipment.
