    摘要: PRISM Thermoplastic Rubber (PTR) is a novel, composite rubber material technology principally compounded from EOL, ambient ground, whole tires through the management of a unique process governed by the application of advanced, quantum field physics. The value from this technology is to provide a virgin-material-analog that may be readily integrated at high ratio, into new tire construction using conventional tire chemistry and manufacturing techniques resulting in a sustainable and significant, positive cost-benefit ratio as compared to current tire manufacturing economics.

    摘要: In a golf ball having a core and a cover of one or more layer, the core is a product molded under heat from a rubber composition which includes (a) a base rubber, (b) a co-crosslinking agent which is an α,β-unsaturated carboxylic acid and/or a metal salt thereof, (c) an organic peroxide, and (d) water, wherein the content of component (d) is set within a specific range and components (b) and (c) are included in relative amounts that satisfy a specific condition. The core has a specific compressive deformation and a specific hardness difference between the center and surface thereof. Owing to the large hardness difference in the internal hardness profile of the core, the ball exhibits low spin characteristics when hit, improving the flight performance, yet retains a good durability to impact.
