Rhenogran® Pre-Dispersions: LANXESS Innovation Now with Fragon

The rubber industry is undergoing a transformation. The pursuit of greater production efficiency, workplace safety, and sustainability highlights innovative solutions capable of redefining established processes.
In this context, the Rhenogran® pre-dispersions, developed by LANXESS and now strategically distributed by Fragon in Brazil, represent a milestone in the sector.

In the past, powdered additives formed the basis of most formulations, but they no longer fully meet today’s demands for performance, quality, and safety. The natural path forward lies in adopting pre-dispersions — products that offer greater stability, reduced losses, and simpler processing.

This is precisely the paradigm shift that Fragon, in partnership with LANXESS Brasil, now brings to tire manufacturers, producers of technical rubber goods, and the automotive industry.
Throughout this article, we will explore how this strategic partnership is shaping the future of the rubber industry in Brazil, the differentiators of Rhenogran® pre-dispersions, and why this innovation means more productivity, safety, and competitiveness for the market.

A Strategic Partnership Between Fragon and LANXESS Brasil

The collaboration between Fragon and LANXESS Brasil goes far beyond a simple distributor–manufacturer relationship. It’s a strategic alliance combining LANXESS’s global expertise in chemical specialties with Fragon’s strong, agile, and technical presence in the Brazilian market.

This partnership makes a full range of high-performance additives accessible — with local support, optimized logistics, and specialized consulting. For clients, it means not just access to products, but to a network of knowledge that helps develop more robust, safer, and competitive formulations.

The message is clear: Fragon & LANXESS together represent the strength that elevates innovation, safety, and performance standards in Brazil’s rubber industry. This collaboration allows the national market to keep pace with global modernization trends, offering solutions that reduce risks and increase operational efficiency.

From Powder to Pre-Dispersion: The Process Transformation

For decades, powdered additives dominated rubber compounding. While functional, they posed recurring challenges: inhalation risks, storage instability, handling losses, and performance variations.

Rhenogran® pre-dispersions were designed to overcome these limitations. Supplied as masterbatches with controlled and uniform dispersion, they ensure shorter mixing times, greater reproducibility, and stable properties — while creating safer and cleaner working conditions.

This shift — from powder to pre-dispersion — represents a silent revolution. It doesn’t reinvent the process, but optimizes it so significantly that the performance gains become undeniable.

What Are Rhenogran® Pre-Dispersions?

Rhenogran® pre-dispersions are masterbatches developed by LANXESS within its Rhein Chemie line. They consist of homogeneously incorporating fibers or active additives into an elastomeric matrix, ensuring optimized dispersion and maximum compound efficiency.

Specifically, Rhenogran® P91-40/NBR and Rhenogran® P95-50/HNBR contain Twaron® aramid fibers dispersed in NBR and HNBR matrices, respectively. This combination delivers superior mechanical reinforcement, higher elastic modulus, greater tear resistance, and enhanced durability.

Unlike powdered additives, pre-dispersions offer greater dimensional and chemical stability, easier storage, and reduced losses — eliminating unwanted variations during production.

Technical Advantages of Rhenogran® Pre-Dispersions

• Safety and Occupational Health
  The main issue with powdered additives is particle inhalation risk. Rhenogran® pre-dispersions, provided in solid, dust-free form, eliminate this hazard while ensuring a cleaner and safer environment.

• Productivity and Efficiency
  With optimized dispersion, mixtures become faster and more homogeneous, reducing processing time and energy consumption — directly impacting operational costs.

• Economy and Waste Reduction
  Handling powders often leads to significant material loss. Pre-dispersions minimize waste and improve resource utilization.

• Sustainability
  Less waste and dust mean fewer emissions and better environmental compliance — aligned with the sustainability goals of modern industry.

• Stability and Traceability
  Rhenogran® pre-dispersions offer longer shelf life and consistent properties, making quality control easier and production more reliable.

Applications in the Rubber Industry

• Tire Manufacturing
  Improves tear resistance, abrasion resistance, and dynamic fatigue, ensuring safer and more durable tires.

• Technical Rubber Goods
  Ideal for hoses, seals, and conveyor belts, enhancing mechanical strength and reducing maintenance costs.

• Automotive and Industrial Components
  Perfect for applications exposed to high temperatures, oils, and fuels, providing enhanced performance and reliability.
