Butterfly Flextra – Control-Oriented Allround Table Tennis Rubber
Butterfly Flextra is a control-focused, pimples-in table tennis rubber designed for allround players and those looking to improve their technique. With a flexible topsheet, soft sponge, and precise Japanese construction, Flextra delivers high control, good spin, and a stable ball trajectory, making it easy to keep the ball on the table. Made in Japan and ITTF-approved, this rubber is a great choice for beginners, intermediate players, and fans of an allround style—especially when playing with 40+ plastic balls.

Butterfly Flextra stands out with its design focused on control and feel, catering to players seeking consistency and technical development:

• Soft Sponge (32°): The soft sponge (Butterfly scale: 32°, approx. 35–40° on the ESN scale) offers a gentle touch and high control. Its porous structure absorbs impact energy, enabling precise ball handling and supporting topspins, blocks, and serves. Compared to the Butterfly Sriver (38°), Flextra is softer, slower, and more forgiving—ideal for learning technique while still offering great feel.

• Flexible Topsheet: The grippy (not tacky) topsheet is designed with flexibility in mind, extending ball contact for better spin and control. It’s durable, wear-resistant, and optimized for plastic balls—producing consistent trajectories. Compared to Sriver, it offers more spin potential but less speed, making it suitable for players who value precision.

• Pimples Structure: Medium-length pimples with a dense layout support spin and control. They allow easy generation of topspin and backspin while keeping shots stable. In comparison with the Butterfly Tenergy series, Flextra’s pimples are less aggressive and built for allround play rather than maximum speed or spin.

• No High Tension Technology: Unlike Tenergy or Dignics series, Flextra does not use High Tension technology, resulting in lower speed but a more natural feel that emphasizes control and stability. This is especially helpful for beginners or players refining their technique.

Available sponge thicknesses:
• 1.5 mm – maximum control, ideal for beginners
• 1.7 mm – balanced play
• 1.9 mm – versatile offense
• 2.1 mm – more speed and power

The rubber is lightweight (uncut ~60g, cut ~40–45g), similar in weight to Yasaka Mark V or Donic Bluefire JP 03. Available in ITTF-compliant red and black. Butterfly recommends using Free Chack glue when assembling.

Technical Specs Designed for Allround Control Play:
• Speed: 29/100 – Slow rubber for controlled strokes, blocks, and serves. Compared to Sriver (~8/10 speed), Flextra is slower and more stable, not built for offense.
• Spin: 10/100 – Generates decent spin in topspins, backspin serves, and looping. Compared to Sriver (~8/10 spin), Flextra offers greater spin potential—suitable for technical improvement and allround strokes.
• Control: Not numerically rated, but soft sponge and flexible topsheet ensure high control, allowing easy ball placement. Compared to Tenergy 05 (~6/10 control), Flextra is significantly more controllable, ideal for beginners and allrounders.
• Arc/Trajectory: Medium, with a gentle arc (15/100)—good for topspin and controlled blocks. The trajectory is stable and allows precise ball direction. Users often highlight its control and feel, especially during technical shots.

Blade Pairings for Ideal Performance:
Butterfly Flextra pairs well with allround and defensive blades:
• Butterfly Timo Boll J: Maximizes control and feel – perfect for beginners
• Butterfly Timo Boll TJ: Balances speed and control – great for allround play
• Butterfly Andrzej Grubba: Enhances feel – ideal for developing technique
• Butterfly Primorac: Adds stability – suitable for versatile strokes

It also matches well with other allround blades like Yasaka Sweden Extra, where the soft sponge and flexible topsheet compensate for blade stiffness and enhance control/spin. Recommended sponge thicknesses:
• 1.5 mm or 1.7 mm for beginners (FH or BH)
• 1.9 mm or 2.1 mm for intermediate players seeking more speed

Optimized for plastic balls, the topsheet effectively generates spin and stable trajectories.

Ideal For:
• Beginners learning basic strokes (topspin, backspin, block, serve) thanks to high control and forgiveness
• Intermediate players looking for a reliable rubber for allround shots
• Close-to-table play: Blocking, flicks, controlled topspins
• Allround rallies: Looping, backspin serves, counter-attacking

Performance Ratings (User-Based):
• Blocking: 8.5/10 – High control and stable trajectory
• Topspin: 8.0/10 – Generates enough spin for learning technique
• Serving: 8.0/10 – Flexible topsheet supports backspin and sidespin
• Counter-attacks: 7.5/10 – Limited by low speed, but reliable for allround shots

Compared to Sriver, Flextra is more controllable and grippier, suitable for a broader range of players. Users praise its control and feel, but note it’s not ideal for aggressive attackers.

Conclusion – Butterfly Flextra: Allround Control with Japanese Precision
• Speed (29/100): Great for controlled shots
• Spin (10/100): Effective for topspin and serving
• Control: High – keeps the ball on the table easily
• Flexible Topsheet: Generates good spin and consistent trajectory
• Soft Sponge: Excellent feel and forgiveness
• Japanese Quality: ITTF approved, built with Butterfly craftsmanship

Compared to Yasaka Mark V, Flextra is softer and more controllable with similar spin potential. Compared to Donic Baracuda, it has less speed but more stability. Users highlight its forgiveness and versatility, especially for beginners.

Butterfly Flextra is ITTF approved and suitable for beginner and intermediate-level competition play. Its high control keeps the ball in play, while its spin potential helps develop technical shots like topspins and serves. The soft sponge ensures reliability in reactive situations—especially in blocks and counter-attacks. A popular choice among players improving their technique, ideal for both forehand and backhand.

Butterfly Flextra – a perfect balance of control and versatility for developing allround players.
