Use of an impact modifier in a low compression golf ball
A golf ball with improved durability is disclosed herein. The golf ball has a core comprising a polybutadiene material and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 0.5 to 5 weight percent of the core.
1. A golf ball comprising:
a center core comprising a polybutadiene material and a methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 0.5 to 5 weight percent of the center core;
an inner mantle layer disposed over the outer core, the inner mantle layer having a thickness ranging from 0.030 inch to 0.090 inch, the inner mantle layer material having a plaque Shore D hardness ranging from 30 to 50;
an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.070 inch; and
a cover layer disposed over the outer mantle layer, the cover layer composed of a polyurethane material and having a Shore D hardness less than the hardness of the outer mantle layer;
wherein the center core has a compression value ranging from −40 to 60, wherein the compression value=180−(deflection multiplied by 1000), wherein the deflection in inches is determined by applying a 200 pound load to the core.
2. A golf ball comprising:
an inner core comprising a polybutadiene material and a methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 0.5 to 5 weight percent of the inner core;
an outer core disposed over the inner core, the outer core comprising a polybutadiene material;
a mantle layer disposed over the inner mantle layer, the mantle layer having a thickness ranging from 0.025 inch to 0.070 inch; and
a cover layer disposed over the mantle layer;
wherein the center core has a compression value ranging from −40 to 60, wherein the compression value=180−(deflection multiplied by 1000), wherein the deflection in inches is determined by applying a 200 pound load to the core.
3. The golf ball according to claim 2 wherein the mantle layer has a thickness ranging from 0.03 inch to 0.040 inch.
4. The golf ball according to claim 3 wherein a golf ball compression under a load of 200 pounds ranges from 60 to 80, a golf ball COR is at least 0.785, and a golf ball durability score is at least 40.
