DSM in Medical

  Biomedical Polyethylenes

Recent breakthroughs in medical textiles have enabled manufacturers to create various implantable devices ranging from innovative sutures to improved cardiovascular devices. As a leader in ultra-high molecular weight polyethylene (UHMWPE) fiber technology, DSM has played a significant role in developing new materials that help improve orthopedic and cardiovascular implants and procedures and return patients to active lifestyles.

Dyneema Purity® listed in the “Toekomstmakers Top 100”

“The "Toekomstmakers Top 100" is a calling card which shows the innovative strength of businesses and governmental organizations in The Netherlands. It illustrates creativity, entrepreneurship and endurance. The innovations generate optimism. They all provide answers to a wide range of challenges the world faces. Global challenges, Dutch solutions.” For more details please visit Toekomstmakers Top 100 and Toekomstmakers Top 100 and Dyneema Purity® fiber.

Medical-grade UHMWPE fiber technology

The innovative UHMWPE fiber technology, designed for use in humans, has the potential to aid in therapeutic repairs that last longer, create stronger mechanical performance, and increase comfort – contributing to improved quality of life for patients.

Advances in medical-grade fiber technology

These advances in fiber technology have played a role in the shift to medical grade UHMWPE-based textiles. In orthopedics, UHMWPE fibers offer extreme strength yet much more flexibility than metal. In cardiovascular, replacement of PET fibers by UHMWPE fibers creates the potential to reduce device size. This allows medical device manufacturers to react to market trends by designing improved devices needed by an aging population and those living more active lifestyles. With its superior strength and smaller profile, DSM’s UHMWPE fibers, known as Dyneema Purity® fibers, help medical device manufacturers develop the durable, low profile devices needed to meet the growing trend toward minimally invasive surgery.

Dedicated medical-grade UHMWPE fiber production

DSM is a leader in biomedical materials, with more than 500 patents in UHMWPE and the only company with a dedicated production facility for producing medical grade UHMWPE fibers. Our Dyneema Purity® fibers offer medical device manufacturers freedom of design to meet challenges thanks to their high strength, low profile, superior abrasion resistance and flexibility.

Dyneema Purity® medical grade UHMWPE fibers

Not only are Dyneema Purity® fibers 15 times stronger than steel, they’re also soft and highly pliable. Materials made with these fibers are resistant to fatigue and abrasion, which can contribute to the device durability and lifetime. They meet our brand promise of improving the quality of life for patients by helping engineers give physicians and other medical practitioners the most advanced tools available.

DSM sustains its leadership position through continuous innovation of new grades based on feedback from medical device designers. We offer the following grades of Dyneema Purity® fiber:


Technical Support

DSM offers customers unmatched technical support. At our Technical Center in Europe, a dedicated medical team with years of hands-on experience can advise on mechanical testing and can connect you with biomedical textile experts to help with fiber processing.


You don’t have to take our word for it when we describe the excellence of Dyneema Purity® fibers. See what others are saying:

From an orthopedic surgeon:

“After years of research, fiber constructions made of medical grade UHMWPE fiber are quickly emerging as an alternative to steel. Its properties allow for flexible design of constructions, and its smaller dimensions enable UHMWPE fibers to be used in smaller implants which are ideal for new, minimally invasive surgical techniques that can lead to shorter hospitalization and faster recovery times.

– Dr. Lodewijk van Rhijn, Orthopaedic Surgeon at University Hospital Maastricht, The Netherlands

From customers and trusted specialist:

“Strong sutures are an important trend within the orthopedic field. Biomet is pleased to be able to offer this next generation suture – MaxBraidTM – containing Dyneema Purity® fiber to the orthopedic community. Our Lactoscrew is the strongest anchor, and it is great to attach the strongest suture to it.”

– Kevin Stone, VP of Operations, Biomet Sports Medicine Inc.

“Biomedical Structures is pleased to have entered into a new cooperative relationship with DSM. With material selection becoming paramount to the performance of medical devices and components, we recognize the value that DSM has brought to this market through the Dyneema Purity® line of UHMWPE fibers. This new relationship will add immeasurable value to new product design and production processes.”

– John R. Gray, President, Biomedical Structures

From a patient:

“As a successful Olympic Weightlifter from 1980 to 2000, I earned countless titles and awards while my shoulders paid the price. My orthopedic surgeon used Dyneema Purity® fiber in the surgeries to reattach both rotator cuffs, and I could not be more pleased with the results. Shortly after my first surgery I was able to return to my full exercise regimen, and while I am currently recovering from my second surgery, I expect the same successful outcome. With the innovative repair of my shoulder tendons, I can appreciate my past successes while still enjoying an active future.”

– John Coniff, former Olympic Weightlifter and Global Business Segment Manager, Sulzer Metco
