OMG! What is latex?
Latex can be purchased per meter, per centimeter, per sheet, per roll, but there are also pre-cut latex strips for sale. Is it a fabric, is it textile, is it plastic? Well... what is latex?
This is what Wikipedia says about latex rubber:
Latex is a thick milky emulsion, the Brazilian rubber tree (Hevea brasiliensis) juice, or similar plants such as Castilla elastica;
Latex is unvulcanized natural rubber, a solid but still flexible substance that can be made from this rubber tree juice, and used to be the basis of all rubber products, such as rubber balls, tires, flat glue, condom, gloves, clothing and latex paint;
The word latex is usually used to indicate latex paint today.
Latex comes from the rubber tree
Making a knife recess in the tree bark (at an angle of 30 °) to the cambium. At the end of the notch, a gutter is placed with a collecting tray, usually of aluminum, so the latex is collected dropwise and can then be collected by buckets in buckets.
Latex made of Castilla elastica, processed with juice of the Ipomoea alba, was used in Mexico for 3000 years ago, among other things for making rubber balls.
The Hevea natural rubber was taken home from home in 1736 by the French researcher Charles Marie de La Condamine, after which rubber developed into a widely used and manufactured product. He would also have devised latex (Latin for milky).
Strength, hardness of rubber latex
The usefulness of latex was increased by chemical operations. Particularly vulcanization, the heating of natural rubber with sulfur, produces a substance with much better properties. The higher the sulfur percentage, the harder the rubber becomes.
Natural latex is a suspension of many hundreds of natural polymer particles (both rubber, a polymer of isoprene, and proteins). At least 75 of the proteins are allergens; Latex can cause a skin allergy. For medical applications, for example, gloves for surgery, synthetic rubber is used, made from isoprene or the similar neoprene.
Also in other applications, a lot of synthetic rubber is used today. Latex paint, in spite of its name, consists of synthetic dispersions. In addition, natural latex is still produced on a large scale, on rubber plantations, which can only exist in tropical areas.
Latex rubber plantations videos on YouTube
Have a look at YouTube there are several movies made on rubber plantations in mainly Asia.
