The characteristic of the POLY STAR tennis string was made to integrate the elastic properties of natural gut. Research objective of the former HOECHST AG was to develop a tennis string combining the advantages of synthetic and natural gut in one product. The result was the world first POLY STAR tennis string entering the market in 1981.
POLY STAR CLASSIC
The first POLY STAR tennis string and the first monofilament polyester series introduced in the market internationally is the "CLASSIC". At it’s core, it has remained virtually unchanged with only slight modifications to meet ever-changing requirements throughout the years. The POLY STAR CLASSIC, like all POLY STAR tennis string, are inherently gentle on the arm, since they have been engineered to mimic the elastic properties of a natural gut string.
POLY STAR ENERGY
In 2004 the "ENERGY" was developed. In comparison with the CLASSIC, it is slightly more flexible and softer. It offers an optimal controllable acceleration and very good spin absorption with excellent elasticity and long durability. Characteristics praised by top players such as Rainer Schüttler.
POLY STAR TURBO
In 2008 the "TURBO" was introduced with it’s distinctive star profile. It’s structured grip-like surface property is achieved by a special spinning process that optimizes both topspin and slice.
POLY STAR STRIKE
In 2010 the POLY STAR STRIKE was developed, a monofilament, co-polyester tennis string. The “STRIKE” derives its profile surface from a unique spinning process - ideal for both topspin and slice players.
