    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.

    This fiber exhibits poor heat resistance and will melt at 135°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):144 - 152
