Ultra-High-Molecular-Weight-Polyethylene (UHMWPE) fibers
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 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.
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 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.
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® 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 three grades of Dyneema Purity® fiber:
- Dyneema Purity® SGX grade: A general purpose, highly versatile, very strong medical grade UHMWPE fiber used to improve implant performance. More>
- Dyneema Purity® TG grade: As strong as the SGX grade, yet with significantly thinner diameters to lower the profile of implants. Designed for use in cardiovascular devices, for example. More>
- Dyneema Purity® UG and VG grade: A fiber created specifically for the development of heavy duty orthopedic applications that demand the highest mechanical performance. Available in white and blue. More>
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.
