The racket, blade and rubber
What the Laws actually regulate about a table tennis bat — the 85% wood rule, the exact thickness limits for pimpled and sandwich rubber, and the pimple density range.
Overview
The Laws are permissive about the racket itself and strict about its covering. The racket may be of any size, shape or weight, but the blade must be flat and rigid.
At least 85% of the blade by thickness must be natural wood. An adhesive layer within the blade may be reinforced with fibrous material such as carbon fibre, glass fibre or compressed paper, but must not be thicker than 7.5% of the total thickness or 0.35 mm, whichever is smaller.
Two kinds of rubber, two thickness limits
A side of the blade used for striking the ball must be covered with either ordinary pimpled rubber, pimples outwards, with a total thickness including adhesive of less than 2.05 mm; or sandwich rubber, pimples inwards or outwards, with a total thickness including adhesive of less than 4.05 mm.
Both figures include the adhesive, which is why the limits are quoted to two decimal places. A tolerance may be specified in the relevant technical equipment document.
What each rubber actually is
Ordinary pimpled rubber is a single layer of non-cellular rubber, natural or synthetic, with pimples evenly distributed over its surface at a density of not less than 10 per cm² and not more than 30 per cm².
Sandwich rubber is a single layer of cellular rubber — the sponge — covered with a single outer layer of ordinary pimpled rubber, where the pimpled layer is not more than 2.0 mm thick. The sponge underneath is what gives a modern attacking rubber its speed and its ability to grip the ball for spin.
The two sides must be different colours
Because different rubbers produce radically different amounts of spin, a player who could hide which side they were using would have an enormous concealed advantage. The Laws therefore require the two sides of the racket to be clearly distinguishable by colour.
This is one of the clearest examples in any sport of a rule written purely to preserve information symmetry: the equipment is not restricted, but the opponent must be able to see which of it is being used.
