No. 3 Boost Strings

The Li‑Ning No. 3 Boost is a high-performance badminton string aimed at intermediate players who demand explosive repulsion and sharp hitting feel. With an ultra-thin 0.63 mm gauge, it delivers maximum repulsion power, allowing shuttle speed to increase with minimal swing effort. The core is made from heat-resistant nano-braided multifilament, while its outer layer uses high-intensity, heat-resistant nylon, resulting in even tension distribution across the racket frame . It is coated with a compound resin that adds elasticity and enhances durability. Its crisp, clear sound also ranks high—perfect for those who enjoy a responsive acoustic feedback during rallies. With shock absorption rated 9/10 and control rated perfect, it offers power and precision in one package.

Material & Properties

• Thickness (Gauge): 0.63 mm (±0.01 mm), ultra-thin for high-speed repulsion performance

• Core Material: Heat-resistant, nano-braided multifilament (for elasticity and tension retention)

• Outer Material: High-intensity, heat-resistant nylon woven to maintain stable string bed and vibration control

• Coating: Special compound resin enhances string elasticity, provides smooth surface finish, and helps maintain tension

Performance Metrics

• Repulsion Power: 10/10—excellent for fast smashes and drives

• Control: 10/10—precise placement and touch shots possible

• Hitting Sound: 10/10—sharp, satisfying acoustic feedback

• Shock Absorption: 9/10—reduces strain on the arm during play

• Durability: 6/10—trade-off between ultra-thin gauge and longevity; best suited for players prioritizing repulsion over lifespan

Length & Weight

• Total Length: ~10 metres of string per reel, enough for full-stringing of Malaysian adult rackets

• Weight (approx.): ~25 g per reel (varies slightly by packaging and variant)

Usage Instructions

1. String your racket to a recommended tension range of 24 lbs to 28 lbs (≈ 10.8–12.7 kg) for optimal balance between control and power.

2. Use a sturdy professional stringing machine—ensure tension increments are incremental and smooth to avoid breakage.

3. Before each match or practice session, inspect string bed for any nick or warp; replace if compromise is detected.

4. Rotate play style between attacking strokes (smashes, clears) and net play to balance string wear.

5. After play, wipe racket frame clean and keep straight, not twisted, in your racket tube or cover.

Precautions & Care Tips

• Do not over-tension beyond recommended lbs/kg limits—ultra-thin strings are more prone to snap under excessive tension.

• Avoid exposure to direct sunlight or high humidity, which can degrade coating and reduce tension retention.

• Do not wet or wash the string—moisture can weaken the resin and multifilament structure.

• Replace strings promptly if fraying appears, sound dulls noticeably, or repulsion decreases significantly, to prevent losing performance and comfort.

Recommended For

• Intermediate to advanced players who prioritise explosive smash power and fast rally speed

• Players seeking excellent touch and control with precise shot-making

• Clubs or stringers catering to players who prefer premium feel and high-performance feedback

• Suitable string for Malaysian indoor court conditions (room temperature ~25 °C–30 °C, controlled humidity)
