PMB 120/200 Polymer Modified Bitumen Manufacturers

PMB 120/200 is a very soft Polymer Modified Bitumen with a penetration range of 120 to 200 (0.1 mm) at 25 °C. It corresponds to Class 9 in the stated EN 14023 classification. This grade mainly serves sealing applications rather than structural strength.

Because of its soft consistency, the binder can wet aggregate during suitable spraying operations. Moreover, its polymer modification helps the binder film hold chippings, accommodate movement, and limit water entry into the pavement. It can also suit asphalt work in very cold regions, where a firmer binder may become too brittle for the intended application.

Within the Tiger Bitumen Polymer Modified Bitumen range, PMB 120/200 sits between PMB 90/150 and the softer PMB 200/300. Therefore, buyers should compare the complete product designation and declared properties before selecting a grade.

Tiger Bitumen is the product brand of HY International Group. Export enquiries for PMB 120/200 are assessed against the complete EN 14023 designation and the property classes stated in the buyer’s project specification.

Tiger Brand PMB 120/200 Specifications (EN 14023)

The PMB 120/200 name defines its penetration range. However, it does not establish every performance requirement. The applicable specification must also state the softening point, cohesion method and class, and other required property classes.

Requirements for soft sealing binders can vary between markets and projects. Therefore, confirm the complete designation and each applicable property class against the relevant product specification before accepting an order.

The Softening Point Margin on a Very Soft Grade

For a binder this soft, the declared softening point helps buyers assess the risk of bleeding and tracking in warm weather. The full designation may be written as PMB 120/200, where represents the declared minimum softening point in °C, if that format applies to the product specification.

Before selecting the binder, assess the following site conditions:

PMB 120/200 Properties

• Low working viscosity. Its very soft consistency can support spraying and aggregate wetting at suitable application temperatures.
• Cohesive, elastic films. The polymer helps the binder film hold chippings and recover after deformation. As a result, it can offer properties that plain soft bitumen may not provide to the same extent.
• Low-temperature flexibility. This grade may suit projects in severe winter conditions and areas with repeated freeze–thaw cycles, subject to the declared performance classes.
• Surface sealing. A continuous binder film can help seal fine cracks and limit water entry into the pavement below.

Applications of PMB 120/200

• Hot-applied surface dressing and chip seals, where the project specification calls for a very soft modified binder.
• Stress-absorbing membranes on cracked pavements.
• Road resealing programmes that aim to improve waterproofing and restore surface texture on ageing roads.
• Asphalt applications in very cold climates, where the specified performance requirements call for a soft modified binder.

Selecting PMB 120/200

PMB 120/200 may suit sealing work and certain cold-climate applications. However, the project specification always takes priority. Use the following comparison as a general guide when evaluating alternatives:

Manufacturing and Export of Very Soft PMB

Very soft PMB needs careful production control because the polymer contributes to the binder’s strength and elasticity. First, the manufacturer must select a compatible base bitumen. Next, the production process must disperse and mature the polymer properly.

The finished binder must also remain homogeneous during storage. This consistency helps maintain uniform performance throughout the tank. In addition, maintenance and resealing programmes often operate within tight seasonal windows, so delivery timing and storage stability matter alongside technical compliance.

For an export quotation, provide the complete designation, the required cohesion method and class, all other specified property classes, the order quantity, the destination port and the planned works season. HY International Group’s export team can then check these requirements against the relevant product specification before preparing a quotation.

Handling PMB 120/200

PMB 120/200 may reach spraying viscosity at lower temperatures than firmer PMB grades. Nevertheless, always follow the heating and application temperatures stated in the specific product documentation.

Avoid local overheating around heating coils, and keep hot storage periods short to help protect the polymer. For new seals, restrict traffic speeds until the binder has cooled and the chippings have settled, in line with the project method statement.
