Bitumen 90/25 — High-Softening, Low-Penetration Oxidized Bitumen Supplier

Oxidized Bitumen 90/25 is air-blown bitumen with a softening point of 90°C and penetration of 25 dmm, offering high heat resistance and durability.

It is ideal for waterproofing, roofing, insulation, pipe coating, and industrial applications requiring durability and heat resistance.

Its 90°C softening point and moderate-low penetration are achieved through the air-blowing process, designed specifically for industrial waterproofing, insulation, and corrosion-resistant applications.

Bitumen 90/25 has higher penetration (softer) than 90/15, giving it slightly more flexibility while still maintaining strong heat resistance for industrial use.

Bitumen 90/25 is typically tested per ASTM D312 for softening point, penetration, and related industrial specifications.

Application temperatures generally range from 195–220°C, depending on the specific hot-applied process.

Store in a cool, dry, covered area away from heat sources, in sealed drums or blocks to prevent moisture ingress and contamination.
