Blown Bitumen, also known as Oxidized Bitumen, is a refined bitumen product manufactured by blowing air through penetration-grade bitumen under controlled conditions. This process alters its chemical structure, enhancing its softening point, reducing penetration, and improving elasticity compared to conventional bitumen. Blown Bitumen remains solid at room temperature but softens upon heating, making it an ideal choice for industrial applications requiring superior thermal stability, water resistance, and durability.

It is classified based on softening point and penetration grade, such as 85/25, 90/40, and 115/15, where the first number represents the softening point (°C) and the second denotes penetration (dmm).

Key Benefits

High Thermal Stability – Maintains optimal performance under extreme heat conditions, ideal for hot climates and industrial applications.
Superior Water Resistance – Excellent impermeability makes it highly effective for waterproofing and insulation projects.
Versatile Grades for Custom Applications – Available in a variety of grades to match different industry specifications.
Long-Term Stability & Shelf Life – Solid and stable composition ensures prolonged durability in storage and transportation.

Application & Industries

Roofing, Insulation, and Waterproofing – Used in roofing felts, vapor barriers, and foundation waterproofing solutions.
Pipeline Coating & Steel Protection – Provides corrosion resistance for pipelines and structural steel components.
Rubber & Chemical Industry – A key ingredient in rubber production, sealants, and chemical formulations.
Paints, Adhesives, and Mastics – Serves as a binder in paints, industrial adhesives, and filling compounds.
