Golf Ball With Improved Durability
A golf ball with improved durability is disclosed herein. The golf ball has a mantle layer comprising a blend of ionomers and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 5 to 15 weight percent of the mantle layer.
1 . A golf ball comprising:
a core composed of a polybutadiene in an amount greater than 60 weight percent, zinc diacrylate in an amount of 10-50 weight percent, zinc oxide in an amount of 1-30 weight percent, zinc stearate in an amount of 1-20 weight percent, peroxide initiator in an amount of 0.1-10 weight percent, color in an amount ranging from 0-10 weight percent, barium sulfate in an amount ranging from 0-20 weight percent, and zinc pentachlorothiophenol in an amount of 0-10% weight percent;
an inner mantle layer;
an outer mantle layer disposed over the inner mantle layer, the outer mantle layer consisting essentially of a first ionomer in an amount ranging from 25 to 60 weight percent of the mantle layer, a second ionomer in an amount ranging from 25 to 60 weight percent of the mantle layer, a third ionomer in an amount ranging from 5 to 20 weight percent of the mantle layer, and a methyl methacrylate, butadiene, styrene (MBS) in an amount ranging from 5 to 15 weight percent of the mantle layer, the outer mantle layer having a thickness ranging from 0.03 inch to 0.07 inch; and
a cover layer disposed over the mantle layer.
2 . The golf ball according to claim 1 wherein the outer mantle layer has thickness ranging from 0.03 inch to 0.07 inch.
3 . A golf ball comprising:
an inner core composed of a polybutadiene in an amount greater than 60 weight percent, zinc diacrylate in an amount of 10-50 weight percent, zinc oxide in an amount of 1-30 weight percent, zinc stearate in an amount of 1-20 weight percent, peroxide initiator in an amount of 0.1-10 weight percent, color in an amount ranging from 0-10 weight percent, barium sulfate in an amount ranging from 0-20 weight percent, and zinc pentachlorothiophenol in an amount of 0-10% weight percent;
an outer core disposed over the inner core;
a mantle layer disposed over the outer core, the mantle layer comprising a first ionomer in an amount ranging from 25 to 60 weight percent of the mantle layer, a second ionomer in an amount ranging from 25 to 60 weight percent of the mantle layer, a third ionomer in an amount ranging from 5 to 20 weight percent of the mantle layer, and a methyl methacrylate, butadiene, styrene (MBS) in an amount ranging from 5 to 15 weight percent of the mantle layer; and
a cover layer disposed over the mantle layer.
