THERMONYL – CHALLENGE

Using the best quality Italian nylon and applying more than – 15 ”inhouse” processing stages in order to obtain Thermonyl the first highperformance nylon monofilament available on the squash market.DoubleAR has succeeded where others have failed: to create amonofilament with the same (or even more…) power than top qualitymultifilament, capable to tolerate the extreme shock caused by theimpact of a squash ball. Thermonyl is used for Salming Challengestring.

For Thermonyl we can also offer a Bi-color technology, which allowsto us to produce a unique filament with alternating colors withoutafflicting the yarn properties. The Challenge string enablesus to offer an infinite range of possible customizations possibilities.

The exclusive Thermonyl material gives the Challenge string:
- Pure performance
- Great feel, and;
- Exceptional power.

Features
Dynamic Tension Loss

This test shows that the Challenge string, due to the extra elasticity of the Thermonyl polymer, needs to be tensioned 1 kg more than the player's common tension in order to counteract the significant tension loss registered in the first 12 hours ("setting time"). The setting time is the "price" we have to pay for giving to the player an extraordinary energy in the sweet spot. 

Reactivity Test

The graph displays a stress test developed by DoubleAR that measure the rebound properties of the string. Notable is that Instinct Response has +10,70% greater rebound property compared to the Salming Challenge Slick.

Elastic Deformation

Salming Challenge is 59% more elastic than Competitor 1, and 15% more elastic than Competitor 2. Graph measures the elasticity of a string (Dan). Focusing on 10 dan data (equivalent of 10kg, averagesquash tension)
