THE IDEAL BOUNCY MATERIAoLo FOR RACKET COVERINGS BORN IN AMERICA AGES AGO.
Super Ball or Superball is a toy bouncy ball based on a type of synthetic rubber invented in 1964 by chemist Norman Stingley. It is an extremely elastic ball made of Zectron,[1] which contains the synthetic polymer polybutadiene as well as hydrated silica, zinc oxide, stearic acid, and other ingredients.[2] This compound is vulcanized with sulfur at a temperature of 165 °C (329 °F) and formed at a pressure of 3,500 psi (24 MPa). The resulting Super Ball has a very high coefficient of restitution,[3][4][5] and if dropped from shoulder level on a hard surface, a Super Ball bounces nearly all the way back; thrown down onto a hard surface by an average adult, it can fly over a three-story building.
A reputable rubber manufactory of China is known to have adopted Stigley's "magic" formula as it is, with only slight modification. (don't ask me names, please).
They would advertise their table tennis rubbers as a "high tension material" of a new generation. Yes, this Chinese novelty sponge feels extremely bouncy much like that of ® Dignics Tamasu.
