PMB 200/300 Polymer Modified Bitumen Supplier and Exporter

PMB 200/300 is a very soft penetration grade in the Polymer Modified Bitumen range. Its penetration range is 200–300 tenths of a millimetre (0.1 mm) at 25 °C, measured according to EN 1426. Compared with PMB 120/200, this grade has a higher penetration range. However, the full product designation and declared performance requirements must be checked before selecting it for a project.

Key Characteristics and Benefits

• Very soft, high-penetration binder: The penetration range of 200–300 (0.1 mm at 25 °C) identifies this as a very soft grade.
• Potential low-temperature flexibility: Its softness may support applications that require a flexible binder in cold conditions. Confirm performance against the product data sheet.
• Polymer-enhanced properties: Polymer modification can improve elastic recovery and cohesion compared with an appropriate unmodified base bitumen, depending on the formulation.
• Project-specific handling: Processing and application temperatures depend on the product formulation. Therefore, always follow the supplier’s technical data sheet.

Applications

• Specialist binder applications where the project specification requires a very soft polymer-modified bitumen
• Flexible surfacings and treatments where the approved design requires this grade
• Applications that require movement tolerance, subject to confirmation by the project engineer
• Production of other bituminous materials when the specified formulation calls for a soft, polymer-modified binder

Selecting the Right Grade

PMB 200/300 is a specialist grade and should only be selected when the project specification supports its use. For many asphalt surfacings, a different grade may be more appropriate. For example, PMB 120/200 or PMB 90/150 may be considered where their properties meet the design requirements. Ultimately, the project specification and verified product data should determine the suitable grade.

Technical Specifications

EN 14023 provides a framework for specifying polymer-modified bitumen used on roads, airfields and other paved areas. For PMB 200/300, the grade designation indicates the penetration range at 25 °C, measured using EN 1426. The full designation also identifies the applicable softening-point requirement under EN 1427. In addition, the declared specification may include cohesion, resistance to hardening, flash point and, where applicable, Fraass breaking point, elastic recovery and storage stability.

Requirements depend on the full product designation and the applicable specification classes. Therefore, Tiger Bitumen should confirm the applicable designation and declared properties for the offered supply in the product documentation and quotation.
