Infinity is a blade with a Limba top ply and a springy ply under it so it is a little bouncy. And in the name, "Infinity VPS with Diamond Touch," VPS is a heating process. One of the things that would do is make the middle ply have more bounce. And Diamond Touch is a hardening process applied to make the outer ply, yep, you got it, harder.
Here:
"The Infinity VPS V with Diamond Touch, with the brand new Veneer Precision System (VPS) technology is built with two hand-selected middle veneers that are treated with a unique and exact heating and cooling process with precisely measured time and temperature. The Diamond Touch technology gives the outer veneers extra hardness and the surface an incredibly smooth finish; combined with the VPS technology the result is an offensive lightweight blade with outstanding solid touch and feeling. Infinity VPS V gives you the possibility to master the key elements in today's modern game: aggressive receives which help you gain the upper hand at an early stage, and the possibility to follow up with powerful and aggressive topspin shots. Developed together with top players from the Chinese National Team, the Infinity VPS V suits the more offensive minded player with powerful topspin strokes!"
