UHMWPE
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.

UHMWPE RESISTANCE GUIDE
UHMWPE fibers like Spectra® or Dyneema® 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.
This fiber exhibits poor flame resistance and will melt at 135°C. It is not advisable to use in any application where an open flame is present.
