Bitumen 85/35

Definition of Bitumen 85/35

Bitumen 85/35, also referred to as oxidized grade 85/35 or
blown asphalt 85/35, is a semi-solid grade of pure petroleum bitumen.
Manufacturers produce it by blowing hot air through an asphalt flux derived
from petroleum bitumen (often grade 60/70). The numbers 85/35 indicate the
midpoint of the material’s softening point (in °C) and penetration
(in 1/10 mm), respectively.

For instance, the softening point value is measured by the Ring and Ball
method (ASTM D36), and the penetration value follows IP49 or ASTM D5. Gold
Bitumen ensures the quality of our oxidized 85/35 by arranging international
inspectors to check its quality and quantity during loading. Our QC team also
controls production with batch test reports before shipping. Moreover, Gold
Bitumen meets the ASTM standard for product quality.

Uses of Bitumen 85/35

Oxidized grade 85/35 has many uses across industries such as chemical,
construction, and manufacturing. For example, it appears in paints, lacquers,
varnishes, paper-pulp-board, textile processing, and road construction. It
also works well for crack seals, repairs, roofing, and civil engineering tasks.

Additionally, companies use this product to seal and insulate buildings,
manufacture adhesives, bind dust, and impregnate materials.  grade
85/35 performs well in asphalt-based paints to protect metals from corrosion.
It also lines public works structures and serves as a base for synthetic turf.
Typical applications include water-proofing and corrosion resistance for pipe
coating, Portland cement pavement, paint manufacturing, caulking, mastics, and
damp proofing.

This grade of bitumen suits insulation in bitumen membrane sheets. The
automobile industry employs it for car undercoating because it offers excellent
water-proofing, dust-proofing, and noise-proofing.

Application of  Bitumen 85/35

Always heat oxidized grade 85/35 to about double its softening point so it
achieves the desired flow and viscosity. Surfaces must remain dry and clean
before application. You should remove loose particles, formwork, curing
products, irregularities, and slurries prior to use.

Storage and Handling of Grade 85/35

Oxidized grade 85/35 remains valid for up to ten years with multiple
heating-and-cooling cycles. Please refer to the MSDS for further details.

Packing of  Bitumen 85/35

We offer several packing options for customer convenience, such as Kraft bags,
moldable plastic bags, drums, and bulk containers. Gold Bitumen manufactures
oxidized Grade 85/35 and packages it to meet different needs. This
penetration-grade bitumen results from blowing hot air in a controlled
process until it meets the correct specification.

We can supply oxidized bitumen in any grade, designated by two numbers showing
the softening point and penetration range. For example, grade 85/35 means the
softening point is 85 °C, and penetration is 35 decimillimeters. We produce
this material in compliance with ASTM standards, ensuring it meets the
requirements outlined below.

Guaranty/Warranty of Blown Bitumen 85/35

Gold Bitumen guarantees the quality of blown grade 85/35 by arranging
international inspectors to check each shipment’s quality and quantity. Our QC
team controls production through batch test reports before shipping. We
guarantee that our product aligns with ASTM/EN 13304:2009.
