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


Spectra® Performance Highlights

  • High Strength: UHMWPE fibers possess high tensile strength, making them one of the strongest fibers available, even stronger than steel.
  • Very Lightweight: UHMWPE fibers are extremely lightweight, and even float in water.
  • High modulus: UHMWPE fibers have a high modulus of elasticity, providing excellent stiffness and dimensional stability.
  • Abrasion resistance: These fibers offer exceptional resistance to abrasion, ensuring durability and longevity in demanding applications.
  • Chemical resistance: UHMWPE fibers exhibit excellent resistance to chemicals, including acids and solvents, making them suitable for corrosive environments.
  • Low moisture absorption: UHMWPE fibers have low moisture absorption, allowing them to maintain their properties even in wet conditions.
  • UV resistance: UHMWPE fibers have inherent resistance to ultraviolet (UV) radiation, making them suitable for outdoor applications without significant degradation over time.
  • Good fatigue resistance: UHMWPE fibers show excellent resistance to fatigue, maintaining their performance under repeated loading cycles.
