Oxidized Bitumen for Waterproofing and Roofing Applications

 PETRO TAR CO. is a specialized and international supplier of Pure Oxidized Bitumen (Gilsonite-Free), offering a comprehensive range of air-blown bitumen grades for waterproofing, roofing, and other demanding bituminous applications. Our oxidized bitumen is produced with controlled softening point, penetration, thermal stability, and consistent quality to meet the specific performance requirements of different formulations and end-use applications

Manufacturers of waterproofing membranes understand that the quality of the bitumen used in their formulations has a direct impact on production efficiency, membrane performance, long-term durability, and product consistency. Selecting the right Membrane Grade Oxidized Bitumen is therefore one of the most important factors in manufacturing reliable, high-performance waterproofing membranes.

In today’s waterproofing membrane industry, manufacturers require raw materials with stable physical properties, consistent processing behavior, and excellent compatibility with polymer modifiers and reinforcement materials.

Depending on the membrane type, formulation design, and manufacturing technology, Membrane Grade Oxidized Bitumen can be used as a primary raw material or as a key formulation component to achieve the desired performance characteristics, including softening point, viscosity, dimensional stability, heat resistance, and optimum processing performance in waterproofing membrane production.

Whether manufacturing APP modified membranes, SBS modified membranes, self-adhesive bituminous membranes, roofing membranes, or other bituminous waterproofing products, selecting the appropriate Membrane Grade Oxidized Bitumen helps manufacturers achieve reliable processing, consistent formulation performance, and high-quality finished membranes.

By manufacturing Air-Blown Bitumen (Pure & Gilsonite-Free), PETRO TAR CO. provides a specialized solution developed specifically for the technical requirements of professional waterproofing membrane manufacturers.
