What is in the golf ball?

ByDoug

Although the distance and trajectory greatly differ depending on the material and structure of a golf ball, in order to ascertain "what is inside the golf ball", a movie comparing ten kinds of golf balls cut in half and "10 Golf Balls Sliced ​​Open"is.

10 Golf Balls Sliced ​​Open - YouTube


Compared with 10 types of golf balls with different manufacturers and years of manufacture.


I will use electric powered saws to cut it in half.


The golf ball is fixed in vise.


◆ 01: feather ball
It is made of gloves made of leather made of feathers packed with leather gloves that were used from the 1600s to the 1800s when golf was born.


I will cut it in half with saw roll. Feathery balls were made one by one by crafter's hand work, but durability was low, it seems that feathers in the inside seemed to be popped off as it broke from the joints when used several times.


Dyeing the cowhide in white, forming it into a bag shape, and packing the feathers of goose and ducks inside.


◆ 02: Haskell ball(1898 - 1970 's)
"Haskell ball" is developed by Mr. Cobain Haskell in search of a ball which is harder to break than a feather ball and the distance of flight is extended.


Inside it is filled with rubber wrapped in a round roll.


Looking closely and looking like this, a thin thread rubber is wrapped around the thick rubber core.


◆ 03:SpaldingMade golf ball(1967)


The core part is made of hard rubber, and the outer side is Surarin (surlyn) resin which is excellent in durability is used.


◆ 04: NIKERZN(Resin)


The core is a bright red resin polymer material. 3 pieces of core, case, coverIonomerDepending on the structure, it is said that the shot's flight distance improves by increasing the control.


◆ 05: SRIXONQ-STAR


It is dark purple rubber on the inside, and it is covered with Surlyn cover, which means that the frictional force will increase.


◆ 06: WILSONDUO


The inside is a soft rubber material of bright light blue and has durability.


◆ 07: CALLAWAYSPEED REGIME 1


Different kinds of rubber overlap in two layers, thermoplastic urethane wraps the outside.


◆ 08: BridgestoneTOUR B330 series


By utilizing water in the core manufacturing process in the model released in 2014, it seems that the inside is soft and the outside is hard and the distance is increased.


◆ 09: TitleistNXT TOUR S


Since the core and cover are made of soft material, the compression value is small, and the degree of deformation by impact is large. In addition, the initial velocity of the ball tends to fall instead of decreasing the spin rate.


◆ 10: Taylor MadeTOUR PREFERRED X


The core has 3 layers of ionomer material and the cover is 5 piece structure of soft urethane cover, it seems that balance of flight distance and spin is balanced.


When you look side by side, you can see that the material of the ball and the inner color are quite different depending on the manufacturer.
