What is good for plastic and plastic?
General cooked rubber is more tough, raw rubber is not high temperature, the melting point is low, the melting point of 80 degrees or so, poor elasticity, fragile. Sika high temperature, melting point of about 120 degrees, better elasticity. , Softer for the cooked rubber.
If it is not the racket, cooked rubber is raw rubber to further processing, the raw rubber heated to the specified temperature, and insulation time, and then after some chemical reaction, add some material or remove some of the material.
If it is refers to the table tennis racket, no cooked gum this kind of thing ............ raw rubber refers to the particles up, the diameter is greater than the height of the rubber. Its characteristics are hit the ball sink, rubbing the ball is weak. , So it is particularly easy to control the ball. At present a group of horizontal beat two sides attack players, in order to find the ball changes, using the forehand anti-plastic (pull arc) and backhand rubber (fast dial and short) with the method. Today's world champion Wang Tao and the famous players Chen Jing, Geng Lijuan and so on the use of backhand plastic play, rubber can be used as a straight shot against the negative paste a choice.
Of course, the plastic is better, you say, the construction is not, each piece should be flat, and some places need to bend, cooked toughness is better, when the bend will not break
