I will explain to you what is the moisture content of wood and how to protect and conserve your racket. Your table tennis equipment is not cheap, and you should protect it. Normally, players just use plastic wrap, but it is not enough.
Table tennis blade is the Bats without the rubbers. The blade is the most important equipment in table tennis, much more important than the rubbers.
Avoid Water Absorption in Your Blade
Table tennis blade is made from wood. Your table tennis blade is very sensitive to the humidity. As in many different industries that involve the use of wood, your blade will absorb humidity (moisture content of wood). And the humidity will soften your blade and make it less powerful.
A thin plastic protector is good because:
- Sticky on one side
- Prolongs the life of the rubber and the blade
- Contains two sheets to cover 2 sides
Another good tip: Never store a bare blade. Always cover, glue it with two old rubbers. Why? The two old rubbers react as the cover for the 2 sides of the blade. It will greatly reduce the absorption rate of humidity in the air. I’ve to conserve my old Stiga blade like that. And the blade still plays great even after 15 years.
Your blade expands slightly and starts cupping or warping. You can also lose the feeling, the sharp feel of the blade. Up to a certain amount of moisture content, your blade is damaged.
Moisture content EMC
What is the moisture content and EMC? Why is it important to your blade?
EMC is the amount of humidity absorbed by your table tennis blade (mass gained). It is directly related to the humidity and temperature of the place where you live!
Look at the diagram. EMC depends on Relative humidity and the temperature. The blue line is the EMC for 30C, at 60% humidity, your blade will absorb about 10% of moisture. That means, if your blade weight is 90g, it will absorb about 9g. It’s huge!
How to Protect Table Tennis Blade
- Remember, your table tennis blade doesn’t like water or humidity. Never put your blade in a plastic sack like this. I’ve seen many players put their blades in a sack. It’s wrong! The sack will cumulate and increase the humidity. Look at the top players, they just put their blade in his case without any additional cover.
- Because I understand well how important the effect of humidity, on the blade’s quality, personally I add the silica gel in the table tennis case to keep my racket in a dry condition. The wood quality of my blade is very good, it gives me a sharp and clear feeling even after several years.
- Avoid temperature extremes. Table tennis blades don’t like extremes of heat or cold. Don’t leave your racket on the dashboard of your car.Don’t put your racket in the luggage in the airplane, put it in the hand luggage. It’s very cold in the luggage carbine. In winter, don’t put your racket in the boot of your car. The quality of the wood decreases quickly.
