Dyneema® Fiber

Commonly known as Spectra® or Dyneema® fibers, UHMWPE fiber possesses exceptional mechanical and physical properties. It boasts an extraordinarily high strength-to-weight ratio, making it one of the strongest synthetic fibers available. UHMWPE fiber exhibits excellent abrasion resistance and since it is hydrophilic, has nearly zero moisture absorption.  Keep in mind that UHMWPE fibers do creep more under constant and continual load compared to other high-performance fibers.

On the chemical front, UHMWPE fibers offer high resistance to corrosive substances, such as most acids, alkalis, and organic solvents, making them valuable in industrial settings where chemical exposure is commonplace. However, UHMWPE fibers are not without their shortcomings. They exhibit limited thermal stability, which reduces their performance and longevity at elevated temperatures. While their melting point is approximately 135-147°C, they begin to lose their properties around 100°C. Moreover, UHMWPE fibers possess low flame resistance. In a fire or high-heat scenario, they readily melt and burn.

Frequently Asked Questions

Q: Is UHMWPE available in cut or twisted formats? +
Yes. Beyond continuous fiber we supply UHMWPE in cut and twisted formats, plus coating and braiding services, so you can source raw fiber and secondary processing together.
Q: Does UHMWPE need any special handling for bonding in composites? +
UHMWPE has a low-friction surface that can benefit from surface treatment for better adhesion, and we offer coating services to improve bonding where needed. Tell us your resin system and we will advise.
Q: Can you provide branded Dyneema and Spectra alongside equivalent UHMWPE? +
We supply recognized UHMWPE brands as well as equivalent options, so you can specify by brand or let us recommend a match for your performance and budget.
Q: Do you supply UHMWPE for cut-resistant glove and apparel makers? +
Yes. UHMWPE is widely used in cut-resistant gloves and protective apparel, and we supply it in quantities scaled to both trial runs and volume manufacturing. Contact us with your usage for a quote.
Q: What denier range do you carry for UHMWPE fiber? +
We stock UHMWPE across a range of deniers to suit cut-resistant textiles, cordage, and composite reinforcement. Tell us your construction and we will identify the denier that fits your strength and weight targets.
