    40 degree hardness

    permission to ask
    If the hardness of 40 degrees DHS is equal to what is the European hardness scale?

    Roughly 52 in the ESN scale

    Another important factor to consider, the thickness and hardness of the topsheet.

    For example, TG2 topsheet is thicker and harder than H8. So a 39 degree TG2 feels harder than a 41 degree H8.

    Same story goes among ESN rubbers too.

    DHS rubbers are slower than Euro/Jap rubbers at the same hardness due to the tackiness. So no fuss.

    Why are you guys obsessed with hardness? It has nothing to do with how springy the rubber is. Also, a rubber like R48 will be softer at 2.2mm than 1.8mm even it is it made of the same material. Duromenter readings are a measure of hardness but they use a point, not a round blunt TT ball for testing. What is a durometer degree? How do you use it in a calculation? Obviously it is bogus because there are different scales.
    A spring constant would mean something but no one here talks about things that really matter.

    Frictionless anti has a very hard and almost brittle top sheet. So what?

    Please stay on point
    OP asked a question and it has been answered.

    Imagine going onto a cooking forum, and someone ask, how do you cook abc and then come and ask, why do you want to cook abc....
    So please stay on point

    Hi, brokenball.
    Yes, you tell most of the truth; good to hear from a real pundit throughly versed of rubber materials. Yes, a mere awareness of the Static Hardness is of little practical value. In making comparisons bitween many sandwich rubbers, the "rebound resiience" of topsheet+sponge combination is of real importance. The Schob pendulum is how can we know rubbers that have "catapultive effect" better than Tenergy would do..
