Expanding Possibilities: Launch of POLYBONDTM 8001 Delivers More Opportunities and Value for Our Customers

A new addition to the POLYBOND™ portfolio is helping SI Group reach new applications, address evolving customer needs, and create opportunities for growth.

Growth through innovation starts with an important question: How can we do more for the customers we serve?

For SI Group, that question is helping shape the next chapter of our polymer modifier portfolio. Building on our established technologies, including antioxidants, UV stabilizers, synergistic blends, and ROYALTUF™ EPDM-based impact modifiers, the introduction of POLYBOND™ 8001, which is the first product in the new POLYBOND™ 8000 series, represents an important step in expanding the applications we can serve and addressing material needs that previously fell outside of our portfolio.

The Challenge

Understanding where the market is headed begins with listening to customers and recognizing the challenges influencing their material decisions. Customer performance requirements, changing supply expectations, and the need for cost-effective material solutions all influence how compounders evaluate their options. Customers need suppliers that understand these competing priorities and can provide more choices for balancing performance, material costs, and formulation considerations.

The Solution

POLYBOND™ 8001 expands SI Group's existing polymer modifier portfolio by introducing a polyolefin elastomer (POE) base resin to the POLYBOND™ product family. Designed as an impact modifier for polyamide compounds, including PA 6 and PA 6,6, POLYBOND™ 8001 helps compounders pursue a balance of toughness, stiffness, flow, and tensile performance while providing a cost-competitive alternative to traditional impact modifiers.

The addition also expands SI Group's capabilities beyond existing polypropylene (PP)- and polyethylene (PE)-based offerings, creating opportunities in polyamide impact modification, recycling, and carpet backing applications.

• Delivering Value Across Applications: POLYBOND™ 8001 is designed to address several formulation and processing challenges across different applications.

  • Polyamide compounds: Provides low-temperature impact modification and the toughness required in demanding applications, offering a cost-competitive alternative to traditional EPDM-based impact modifiers.

  • Recycling and carpet backing: Supports compatibility improvements at lower dosage levels than traditional PE- or PP-grafted compatibilizers.

  • Existing formulations: Its drop-in positioning supports integration into established formulations, potentially reducing the need for significant formulation changes.

The Impact

By addressing these needs, POLYBOND™ 8001 gives compounders another option for balancing performance requirements with material costs and formulation considerations. It also enables SI Group to support existing customers in new applications and provide a more comprehensive range of polymer modification solutions.

Early customer engagement is already building momentum.

The introduction of POLYBOND™ 8001 at AMI Compounding & Recycling Expo in Frankfurt, Germany generated encouraging feedback, particularly among smaller compounders. Engaging discussions and positive responses to a technical presentation by Olaf Henschke, Senior Technical Service Manager, highlighted early customer interest and the product's potential across a range of applications.

Following the successful introduction in Europe, SI Group is excited to officially launch POLYBOND™ 8001 in the US market at the AMI Plastics World Expo in Cleveland, OH, November 11-12, 2026 at booth C2119.

POLYBOND™ 8001 represents more than an addition to the SI Group portfolio. It demonstrates how a deeper understanding of customer needs, combined with technical capabilities and cross-functional collaboration, can uncover opportunities in markets where we have room to grow.

By expanding the applications we serve and creating new ways to support customers' evolving needs, SI Group continues to strengthen its position as a solutions-oriented partner and supplier of choice to the plastics and polymer industries.
