Transfer latexit into latex4/28/2023 ![]() Injection molding involves mixing rubber strips. The polymer compound is then forced through a small opening to be vulcanized or cured. ![]() This is done by the barrel and screw of the extruder. The most common synthetic rubber processing techniques are:ĭuring extrusion, you feed the rubber polymer compound into the extruder, which heats it and compresses the material. The plant rolls the rubber into sheets and cuts them into sheets for further processing. Sometimes, they mix in additional ingredients, depending on the end product for the synthetic latex. The manufacturing plant then mixes the synthetic rubber polymers. These chemicals are used to create synthetic rubber polymers, which are clumped and dried, then transported to a manufacturing plant. Some latex is synthetic, composed of petroleum-based chemicals. With more heating, the material can now be made into regular rubber. Once latex is prevulcanized, it is more convenient to transport. Prevulcanization involves chemical treatments and gentle heating at low temperatures. Doing so removes water, so the sheets can be dried and smoked.įinally, latex is prevulcanized. The clumped fluid is then rolled into sheets in a mill. Once latex is ready to be made into smoked sheets of rubber, companies add acid to the latex. Next, companies filter the latex so it can be packaged in drums for its next destination. The rubber creation process begins at the point of harvesting, when they take latex sap from rubber trees. Tappers tend to these cups, collecting the latex when they become full and replacing the collection cups to continue harvesting from the tree until it is appropriately tapped. The latex flows down the grooves and into large cups. Disrupting these ducts allows the latex to flow down grooves that the tappers cut into the tree. Doing so disrupts the plant ducts, which contain latex. To tap a rubber tree, tappers remove thin strips of bark. At this point, the tree is ready to start producing rubber. The latex harvesting process can only begin once a rubber tree is mature-about five years old. From there, they can harvest the latex and send it off to be processed. When tappers peel back the bark, they disrupt the plant ducts to reveal latex, a milky white substance. Latex lives just beneath the bark of these rubber trees. The tree also thrives in Southeast Asian plantations. The composition of latex from different trees varies, but the most common one is native to South America. Most natural rubber latex comes from one species of rubber tree. Before it is processed, rubber tappers harvest latex from trees using a method that has been passed down for generations. The truth is, natural rubber latex does, in fact, come from nature. You may be surprised to think of latex as a natural material, given the strength and man-made feel of so many of its final applications, like tires, rubber gloves, and tennis shoes. Latex is the soft white substance found beneath the bark of a mature rubber tree. Typically, it is composed of about fifty-five percent water and around forty percent rubber material. What is latex made of? The simplest answer: latex is rubber.
