Ashaway Introduces MultiKill Poly Racquetball String

November 1, 2018

Ashaway, RI – Ashaway Racket Strings has introduced a new polyurethane (PU) based, multifilament nylon string for racquetball. Utilizing proprietary new polyurethane technology, MultiKill® 17 is designed to add toughness and durability for players who like to really cut and spin the ball.

“This line has really been developed in response to market demand,” said Ashaway’s Steve Crandall. “Players kept telling us that as the Official String of USA Racquetball and the major string supplier for the sport, we had to see what we could do with this technology, despite the fact that there are already other PU offerings out there. So we did, and are delighted to be able to offer our new MultiKill string to USA Racquetball members and players worldwide.”

A relatively new material for racquetball strings, polyurethane resin can be formulated to offer many different properties, and when combined with other materials, like high tenacity nylon multifilament fibers, can provide strings with exceptional playing characteristics. The key difference with Ashaway’s new PU technology, Crandall explained, is its matrix design.

With other multifilament nylon strings, like Ashaway’s popular SuperKill® XL line, the core and sleeve, or wear layer, elements remain separate and retain some ability to move relative to one another. New MultiKill 17 combines a high tenacity multifilament nylon sheath with a specially formulated polyurethane resin that bonds the string into a single matrix. This gives the string added strength, especially on off center hits near the edge of the frame, and improves tension holding ability. The natural adhesive properties of the polyurethane surface add grip, while the 17-gauge construction maximizes power. At the same time the string retains nylon’s soft feel and comfortable playability.

Ashaway’s MultiKill 17 strings are black in color and 1.25 mm in diameter. They come in 40 ft. individual packages or 360 ft. reels. Recommended string tension is up to 40 lbs.
