About This Item
Spectra® Physical Properties Guide
Spectra® premium UHMWPE fibers possess exceptional mechanical and physical properties. They boast an extraordinarily high strength-to-weight ratio, making it one of the strongest synthetic fibers available. Spectra® fiber exhibits excellent abrasion resistance and since it is hydrophilic, has nearly zero moisture absorption. Keep in mind that Spectra® fibers do creep more under constant and continual load compared to other high-performance fibers, but their other desirable properties make them a top choice for the most challenging of applications.
Spectra® Resistance Guide
Spectra® UHMWPE premium 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, Spectra® 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, Spectra® 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.
This fiber exhibits poor heat resistance and will melt at 140°C. It is not advisable to use in any application where high heat is present.
Acid: Highly resistant to most acids, maintaining their mechanical properties
Alkali: Withstand exposure to most alkalis with minimal degradation
Organic Solvent: Generally compatible with a variety of organic solvents
Continuous Operating Temperature Range (°C): -150 to 70
Short Term Exposure (°C): 100
Melting Temp (°C):140 - 152
