Our factory has three Bounce Ball materials according to the seasonal climate, as follows:

1. Winter Ball: The material is soft, suitable for low temperature 0 ℃ to 10 ℃;
if the temperature is around 0℃, you can directly inflate without stretching;

if the temperature is around 10℃, it is recommended to stretch the ball skin before inflating to avoid deviation.
2. Spring and Autumn Ball: The material is moderate soft and hard, suitable for medium temperature 10 ℃ to 20 ℃;
if the temperature is around 10℃, you can directly inflate without stretching;

if the temperature is about 20℃, it is recommended to stretch the ball skin before inflating to avoid deviation.
3. Summer ball: the material is relatively hard, suitable for high temperature 20 ℃ to 30 ℃;
if the temperature is about 20℃, you can directly inflate without stretching;

for example, the temperature is 30℃ left and right, it is recommended to stretch the ball skin before inflating to avoid deviation.

Special reminder:

1. If you need to stretch the ball skin, be sure to pull hard, the more severe the ball is deformed, the more effective it is; slightly stretched, the ball has no effect without deformation, which is also the main reason why some customers say that it has been stretched, or the deviation.

2. Summer ball is only suitable for high temperature weather, because the material is too hard, the lower the temperature, the smaller the hit, the easier it is to burst; Winter ball is only suitable for low temperature weather, because the material is too soft, the higher the temperature, the softer, the easier it is to miss.

3. If necessary floating ball, we recommend that you choose winter ball or spring and autumn ball., because most of the floating air body blows cold air, if the material is hard, it is easy to burst, so soft material is needed to fight the ball. In case summer Ball available in hot weather, but the material of the ball is too hard, the ball should not be too big(The size of the 20-inch ball cannot exceed 35cm, otherwise it is easy to burst; The size of the 24-inch ball can be about 40cm).
