PMB polymer SBS modified bitumen

SBS modified bitumen manufacturing By Basekim company

SBS modified bitumen, produced by Basekim, represents an advanced solution for modern road construction. Specifically, this product combines high-quality bitumen with SBS (Styrene-Butadiene-Styrene) polymer under carefully controlled conditions of heat and pressure. As a result, Basekim’s SBS modified bitumen offers exceptional durability and flexibility. In turn, this unique blend not only withstands extreme temperature variations but also remains resistant to deformation.

Understanding the advantages of SBS modified bitumen

First and foremost, Basekim’s SBS modified bitumen demonstrates remarkable resilience against temperature fluctuations. This means that during the hot summer months, it does not flow or deform, while in the cold winter months, it retains flexibility without cracking. Moreover, the high viscosity of this bitumen ensures that it adheres strongly to aggregates, preventing any separation during application. Thus, Basekim’s SBS_modified bitumen remains consistent, ensuring a stable and durable surface.

Key specifications that stand out

Basekim’s SBS modified bitumen adheres to strict standards, which is vital for its performance in paving applications. For instance, the penetration levels at 25°C vary across grades, with PMB 120 having a range of 90-150 and PMB 40 offering 30-50. Additionally, the softening points start from a minimum of 50°C up to 60°C, allowing the bitumen to resist deformation under heat. Furthermore, elastic recovery is another important specification; Basekim guarantees at least 70% elastic recovery at 15°C, which enhances the material’s ability to withstand heavy traffic loads.

Analyzing the composition

Moreover, the composition of Basekim’s SBSmodified bitumen goes beyond just bitumen and polymer. In fact, the bitumen consists of natural components like asphaltenes, resins, aromatics, and saturates. To improve the interaction between the bitumen and the polymer, Basekim includes a compatibilizing agent. This agent helps to avoid phase separation and allows the bitumen to maintain its consistency during application. Therefore, this process enhances the overall performance of Basekim’s SBS_modified bitumen across varying temperatures and conditions.

The production process explained

Furthermore, Basekim follows a meticulous production process for SBS_modified bitumen. Initially, the bitumen component is heated in a stirred tank to a temperature ranging from 185°C to 221°C. Subsequently, while stirring, Basekim adds the SBS polymer, which contains specific block copolymers that enhance the bitumen’s flexibility and elasticity. Importantly, this mixture is continuously stirred and maintained at the target temperature for a period of up to 30 hours. Consequently, this careful process results in a stable, homogeneous blend that meets the highest quality standards.

Why choose Basekim’s SBS modified bitumen?

When it comes to infrastructure projects, Basekim’s SBS modified bitumen stands out for several reasons. To begin with, its high viscosity and enhanced elasticity ensure excellent adhesion to aggregates, preventing any separation. Thus, this leads to a strong, resilient pavement capable of withstanding both high and low temperatures. Additionally, its flexibility allows roads to handle heavy traffic loads effectively, significantly reducing the likelihood of cracks. Therefore, by opting for Basekim’s SBS_modified bitumen, construction professionals can achieve longer-lasting results while minimizing maintenance needs.

Benefits for infrastructure projects

For modern infrastructure projects, durability and reliability are critical. Basekim’s SBS modified bitumen fulfills these requirements by providing a product that combines strength, flexibility, and performance. Specifically, it is versatile enough to perform well across various climates and applications. This versatility allows construction teams to achieve extended lifespan results while reducing the frequency of repairs. Ultimately, when choosing Basekim’s SBS_modified bitumen, projects benefit from a trusted material that can withstand extreme conditions and maintain stability throughout the year.

In conclusion, Basekim’s SBS modified bitumen offers an innovative solution for durable and resilient road surfaces. By blending high-quality bitumen with SBS polymers and a compatibilizing agent, Basekim ensures superior performance and stability in every batch. Whether utilized in road construction, repair, or asphalt pavements, Basekim’s SBS_modified bitumen stands out as a reliable choice that meets the challenges of today’s infrastructure needs.
