Across industries, expectations for material selection continue to evolve. From medical devices to consumer goods and packaging, manufactures are increasingly focused on delivering product solutions that combine consistent performance, support regulatory requirements, and enhance overall end-use product quality. Material selection plays a central role in achieving these goals, particularly in applications where long-term performance and product integrity are essential.

Kraton’s MD1672 has been developed to support these priorities. As a next-generation SEBS polymer, it enables oil-free thermoplastic styrenic formulations that deliver improved performance while supporting regulatory requirements and simplified processing. By eliminating the need for oil addition in a TPS compound formulation, MD1672 supports cleaner, performance driven formulations.

A Streamlined Approach to TPS Formulation

MD1672 introduces a simplified approach to TPS formulation by eliminating the need for oil addition, while maintaining ease of processability. This enables manufacturers to achieve consistent production outcomes using familiar processing methods.

Key formulation advantages include:

• Oil-free design with no oil bleed potential
• Low migration profile supporting stable formulations
• Compatibility with standard extrusion and injection molding
• Processable by standard extrusion and injection molding

This combination supports manufacturing efficiency while maintaining formulation consistency, helping reduce variability in production environments.

Delivering Performance You Can Rely On

MD1672 is engineered to deliver performance improvements that directly support durability and product reliability across applications. These enhancements are particularly important in environments that require long-term sealing, flexibility, and material cleanliness.

Key performance characteristics include:

• Improved compression set across temperature ranges
• Enhanced barrier properties over conventional TPS compounds that reduce permeability to gases and moisture
• Low leachables and extractables
• Low fogging and low VOC emissions for cleaner end-use products

Together, these attributes contribute to materials that maintain performance over time while supporting product quality and consistency.

Enhancing End-Use Product Quality

Material performance directly influences how end-use products function and how they are experienced by the users. MD1672 supports the development of products that are clean, durable, and consistent in performance.

Odor-free performance and minimal fogging contribute to improved product appearance and usability, while strong elastic recovery supports sealing and flexibility in demanding applications. These characteristics help manufacturers deliver products that meet both technical requirements and user expectations.

Enabling Versatility Across Application

The performance profile of MD1672 supports its use across a broad range of applications. From medical and healthcare components to food contact and packaging materials, consumer products, and industrial sealing systems, this polymer solution delivers a balance of performance and processability that adapts to diverse end-use requirements.

Its ability to deliver improved compression set up to 120°C, reduced extractables, and strong barrier performance makes it particularly well suited for applications that require high material integrity. MD1672 also provides a viable alternative to silicone rubber in select uses, while supporting efficient processing and design flexibility.

Supporting Sustainability Goals

Sustainability continues to influence material decisions across the value chain, and MD1672 is designed with that in mind. Its oil-free composition and recyclable design, helping simplify material structures and improve end-of-life outcomes.

The material is also compatible with recycled polypropylene in formulations and delivers low VOC performance, thus  aligning performance with broader sustainability objectives.
