MITSUBISHI CHEMICAL　Diamana RF-Series

MITSUBISHI CHEMICAL Diamana RF-Series:

---

A new generation of red, the Diamana™ RF Series, is born.

By increasing the rigidity of the middle portion of the shaft and creating a large difference in rigidity from the tip portion, a shaft behavior with a sense of speed at impact is created.

The new series delivers high launch and the smoothness demanded by athletes.

---

Mitsubishi Rayon Diamana RF Series Shaft incorporates high-strength DIALEAD™ Pitch Fiber by Mitsubishi Chemical into the butt section of the shaft, adding unprecedented strength and control during shaft loading and unloading.

---

The new Diamana™ RF-Series also incorporates for the first time a new hybrid prepreg developed by the engineers at Mitsubishi Chemical. This new prepreg combines boron fiber and Mitsubishi Chemical’s latest carbon fiber innovation MR70. Mitsubishi Chemical’s MR70 by is 20% stronger and has 10% higher modulus than conventional carbon fibers. Strategically positioned in the tip section of the shaft this hybrid prepreg provides unprecedented strength and stability at impact.

【Technology】

DIALEAD  Pitch Fiber

・Diamana features our latest prepreg with DIALEAD Pitch Fiber for outstanding strength and energy transfer with a minimum of shaft deformation. While more costly and difficult to manufacture, the pitch fiber we are using is much stronger than traditional carbon fiber. All prepreg used in our shafts is developed and produced by Mitsubishi Chemical, or our trusted partners, giving us precise control over every step of the process.
