Make and purpose of latex balloons.
The word balloon is derived from the French word ballon which gives the meaning as the large ball. A flexible bag that becomes inflated like a ball when air is blown into it is called the balloon and this is mostly used for decoration purposes and also used by small children for playing. There are various materials like rubber, polyurethane, latex, polychloroprene with which balloons are made. The balloons that are made from latex are called the latex balloons.
Latex is obtained from rubber trees. The processed milk of the rubber tree is termed as latex and these are largely manufactured by countries like Sri Lanka, Malaysia, Thailand and Indonesia as they are rich in rubber cultivation. Therefore most of the latex balloons are manufactured by these countries. This is actually a multibillion dollar business with over 1 billion balloons manufactured every year.
Latex balloons also possess the advantage of being biodegradable and does not cause any harm to the environment when it is torn. Latex can cause choking hazards in children and so it is advisable to keep it out of the reach from children. It is manufactured in an environmental friendly way because it is not required to fell the rubber trees inorder to obtain the latex and it is just got by making a scratch on its trunk.
The standard size of latex balloons are around 11-12 cms and they mostly round in shape or pear shaped. But it is also possible to find balloons from 5 feet to 14 feet with the same shapes. As it is mostly used for decoration purposes there can be printings found on the balloons and also various shapes are available for different occasions.
Latex balloons float for more time in the air when it is filled with helium gas and slowly comes down as the helium gets dispersed through pores in the latex. The floating time of these balloons can be increased upto 24 times more than normal by inserting an aqueous non toxic, non flammable and non corrosive solution in it.
