    Abstract: The present invention relates to a chain link comprising a strip comprising warp yarns and weft yarns, with the warp yarns containing warp yarn A and warp yarn B, with the minimum creep rate of warp yarn B being higher than the minimum creep rate of warp yarn A, wherein the strip comprises a longitudinal core section and at least two longitudinal edge sections, and wherein the concentration of warp yarn A in the core section is higher than the concentration of yarn A in the edge sections of the strip and the concentration of warp yarn B in the edge sections is higher than the concentration of warp yarn B in the core section of the strip. The invention also relates to a chain comprising said chain link and to use of said chain in different applications.

    Abstract: A chain is provided which includes a plurality of interconnected chain-links. At least one chain-link of the chain has a braided core which includes a first primary strand having polymeric elongated elements having a tenacity of at least 1.0 N/tex. The braided core is braided from at least 2 consecutive turns of the primary strand. Also disclosed is a braided endless shaped element suitable as chain-link for the chain as well as a chain which has a tenacity (Ten) in N/Tex and a combined titer of the 2 legs of the chain-link having polymeric elongated elements (T) in MTex satisfying the relationship of Ten≥0.50*T−0.05.
