DSM introduces the first black medical-grade UHMWPE fiber


DSM Biomedical has released its Dyneema Purity Black fiber that is the first and only black ultra-high molecular weight polyethylene (UHMWPE) medical fiber.

The black fiber builds upon what Dyneema Purity fibers are known for like strength, being that it is 15 times stronger than steel. It also has a small profile, high pliability and proven biocompatibility. The Dyneema Purity Black fiber can be used in different medical devices like surgical sutures and cables of SGX (white), VG (blue) and RP (radiopaque yellow) fibers.

It has also been developed to be used in the design of sports medicine applications like orthopedic sutures. The black fibers allow for more complex sutures to be manufactured.

“Having an additional distinct color for high strength orthopedic sutures enables surgeons to perform procedures with more confidence,” said Dr. Richard C. Lehman. an orthopedic surgeon and medical director for the U.S. Center for Sports Medicine. “With better suture management, we can achieve results faster, while simultaneously enhancing accuracy.”

The black colorant in UHMWPE surgical sutures and Dyneema Purity Black fiber is currently under review with the FDA and was submitted through aa Color Additive Petition.

“DSM is committed to improving the lives of patients through groundbreaking, research-based biomedical solutions,” said Carola Hansen, director of product management, polyethylenes at DSM Biomedical. “Dyneema Purity Black fiber further extends our leadership position in medical-grade polyethylene, addressing our partners’ challenge for smarter suturing contrast and enhanced design options. Dyneema Purity Black fiber lays the foundation for a new generation of surgical products for the most intricate medical procedures to truly help patients.
