Vectran® LCP (Liquid Crystal Polymer) fiber boasts exceptional physical properties, making it a highly desirable fiber. Its break strength surpasses that of other conventional fibers, exhibiting remarkable resistance to stretching or tearing. Additionally, Vectran® LCP fiber demonstrates a high modulus, signifying exceptional stiffness and rigidity, which enables it to maintain its shape under stress. Vectran® LCP also exhibits minimal elongation, ensuring dimensional stability even in demanding applications, where maintaining precise tolerances is critical.


Vectran® LCP fiber offers exceptional resistance to abrasion, making it ideal for applications where contact with rough surfaces or high friction is common. Its robust chemical resistance enables it to withstand exposure to various corrosive substances, expanding its versatility across different industries. Additionally, Vectran LCP fiber exhibits low moisture regain, making it highly resistant to moisture absorption and maintaining its mechanical properties even in humid environments.  It does however degrade and discolor in extended UV exposure.

This fiber will degrade with long term exposure to UV light. The fibers will brown and weaken. Please keep this fiber stored away in a dark room and in the UV protective bag the fiber was shipped in.
