Bluestar Silicones Premieres PFAS-Free Self-Lubricating Silicone for Healthcare Applications

Bluestar Silicones today launched SILBIONE LSR 4755 PF, a perfluoroalkyl (PFAS) free, self-lubricating liquid silicone rubber (LSR) that can help device manufacturers attain high performance while addressing the growing demand for PFAS-free material solutions.

Designed for healthcare applications involving patient contact of up to 30 days, SILBIONE LSR 4755 PF combines excellent lubricating properties with efficient processing and strong mechanical performance, according to the company. The two-part, addition-cure silicone elastomer features an integrated lubricating technology that creates a non-stick surface while supporting reliable, high-volume manufacturing.

Unlike traditional self-lubricating materials that can lead to contamination in the mold, SILBIONE LSR 4755 PF incorporates delayed oil bleed technology to help reduce mold fouling and maintain productivity. In addition, SILBIONE LSR 4755PF offers excellent mold release characteristics, enabling shorter cycle times and greater manufacturing efficiency. Its high tear strength and consistent processing behavior make it well suited for demanding healthcare applications where both performance and reliability are essential.

SILBIONE LSR 4755 PF is particularly well suited for components requiring enhanced lubricity performance, including needle valves, check valves, duckbill valves, one-way valves, and molded parts designed to help prevent slit healing. The material has been evaluated according to ISO 10993 requirements for applications involving less than 30 days of body contact, supporting its use in various medical and healthcare devices.

“As healthcare manufacturers navigate evolving regulatory requirements and sustainability goals, they are looking for materials that deliver proven performance without compromising processing efficiency,” said Aneta Clark, NA market manager, Healthcare, at Bluestar Silicones. “SILBIONE LSR 4755 PF provides a PFAS-free solution that combines the low friction performance customers need with excellent mold release, high tear strength, and efficient manufacturing capabilities. We are excited to bring this technology to the healthcare market.”
