INDUSTRY NEWS
Ashaway now markets PEEK-based mono- and multifi lament strings for tennis, racquetball and
squash. In the tennis world, our fl agship string is a PEEK monofi lament called MonoGut® ZX that
can actually rival natural gut in performance and outlasts it in durability. This string is designed for
players seeking both gut-like playability and superior durability in a solid monofi lament string, as
well as players using monofi lament strings in hybrid stringing patterns. Like natural gut, MonoGut
ZX retains tension better than any other synthetic material and provides exceptional energy re-
turn—meaning power. Also like gut, it remains soft at higher tensions, reducing impact shock. This
adds to comfort and what we call 'soft power.' MonoGut ZX contains no polyester, but like its poly
cousins, is excellent at generating spin. But more on that in another column.
In racquet strings, PEEK off ers low dynamic stiff ness that allows it to deform and recover more
completely than other synthetic materials. It can also be made to have exceptionally low creep
under continuous tension, allowing racquet strings to maintain tension and playability longer.
