Frequently Asked Questions about dunlop grand prix hard court tennis balls
The main difference between regular-duty and extra-duty tennis balls is that extra-duty balls, also known as "hard court" balls, have a thicker and more durable felt covering, so they're meant to last longer on hard surfaces.

The reason new balls are sold in plastic canisters is to prolong their shelf life, to keep them as "fresh" as possible until you are ready to play with them. The canister keeps them under about 15 lb of pressure equal to the internal pressure so they dont lose air while in the can.
The modern ball, mostly made in optic yellow colour, has a diameter between 2.575 inches and 2.7 inches and weigh between 56 grams and 59.4 grams. The balls today are made by compression molding of a rubber compound into two separate half-shells which are then assembled together to produce a core.
Often made from macadam or concrete, hard courts are the most neutral of tennis courts. In terms of speed, it's faster than clay and slower than grass, but the bounce is a lot higher due to the harder surface.
As you might guess, tennis balls travel slower on clay courts than they do on hard courts or on grass. The clay absorbs the impact of the ball more readily. Regular-duty balls therefore have a thinner and less fuzzy felt covering so that the balls will pick up less clay when used on those courts.

Welcome to the world of Dunlop tennis balls, used around the globe from recreational courts to Grand Slam stadiums.
Modern tennis balls must conform to certain size, weight, deformation, and bounce criteria to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 6.54–6.86 cm (2.57–2.70 inches). Balls must have masses in the range 56.0–59.4 g (1.98–2.10 ounces).
In the late 1920s Thomas E. Wilson & Co. and the Pennsylvania Rubber Company, respectively, began manufacturing the first pressurized metal tubes for preserving the shelf life of tennis balls. The air pressure in the can was increased to equal the pressure in the ball.
Tennis balls are filled with air and are surfaced by a uniform felt-covered rubber compound. Tennis ball felts comprise wool, nylon, and cotton in a mixture surrounding the rubber edge. The felt delays flow separation in the boundary layer which reduces aerodynamic drag and gives the ball better flight properties.
The ball is placed in a moulding press and heated, curing together the rubber solution on the core and that on the back of the cloth. The heat and pressure also cure the rubber solution in the join between the two covers and moulds it into a smooth seam. The moulded ball is cooled and removed from the press.
The company entered the sporting goods market in 1910, when it began to manufacture rubber golf balls at its base in Birmingham. The company introduced the Maxfli golf ball in 1922. Dunlop extended into tennis ball manufacture in 1924. In 1925, F A Davis was acquired, which had tennis racket manufacturing expertise.
Hard courts are generally made of synthetic or acrylic layers laid on top of a concrete or asphalt foundation. Resin and rubber are also used in some constructions.
