This newly developed, innovative process allows HEAD to control the molecular crystal structure within a monofilament string and engineer different material properties in the outer and the core region of the string, setting it apart from conventional monofilament polyester strings. Highly orientated molecules on the outside of the string generate stiffness and energy efficiency releasing more power and explosiveness. Meanwhile, a more crystalline inner core is adding dampening and touch to the string’s performance.
By creating unique variations in the molecular structure within the cross-section of monofilament strings, HEAD’s CRYSTAL CORE technology opens the door to a new era of polyester strings with unique combinations of ultimate power and feel.
CRYSTAL CORE technology is introduced with the new HEAD HawkTM Tour String. It combines highest possible energy efficiency for explosive power with optimized control and touch in every shot.
