Materials

Polypropylene
Polypropylene is a high-strength, heat-sealable plastic that possesses stress-strain with a similar behavior to gut.

Polyester
Polyester is a stable, highly durable plastic, its rigidity decreases the more it is stretched.

Polyamide
Polyamide, in contrast, is a soft plastic whose rigidity increases the more it is stretched.

Power Ribbons

Power Ribbons are flat tapes made of Polypropylene and Polyamide. They are wound several layers thick so that they overlap and are diametrically opposed, thereby simulating the structure of a natural gut string. This makes it possible to produce strings that are elastic and robust at the same time.

Strings

Spring Load

Normally a monofilament polyester string is plastically deformed through tautness, thus losing a lot of tension. This technology enables the molecule chains of a monofile string to contract again, resulting in minimal tension loss and increased stability of playing properties as well as increased arm protection.

Strings

Double Heating

This technology refers to a thermal after-treatment consisting of multiple heating processes that are applied to the string. The heating evens out any irregularities and also eliminates internal stresses. The results are pliable, uniformly elastic strings.

Strings

Liquid Wax

Once manufacture is complete the string is refined with a layer of wax. This layer simplifies stringing the racquet and significantly extends the life of the string itself by reducing wear.

Strings

Braided Core

The braided core is a tightly plaited cord located in the string‘s core. Due to its exceptional structure, it gives the string uniform elasticity and high resilience capabilities.

Strings

Pre-Stretched

ISOSPEED strings are pre-stretched. Pre-stretching the string core or the entire string reduces the loss of tension to a minimum. At the same time, this allows for lower tension weights.

Strings

Low Friction

Reducing string-friction offers some advantages. String movement is reduced, the spin potential will be optimized thanks to the snap back-effect and last but not least durability is increased. To reach this target ISOSPEED is using an additive - Low Friction!
