Features of styrene butadiene rubber and styrene butadiene latex
Introduction of both products
Usually the two names latex and styrene butadiene rubbers are used interchangeably, although they are two distinct materials that are used in different ways to produce different products. The similarity between the two is that they are both composite polymers and are usually made by a process called emulsion polymerization. In addition, both substances contain organic compounds called styrene and an industrial gas called butadiene. Styrene is the product of the reaction between gasoline and ethylene at room temperature, which is an oily, colorless liquid with a sweet odor. Butadiene, on the other hand, is a by-product of ethylene hydrocarbon and is known as a colorless gas that smells like gasoline. The similarities between the two materials are that both have several advantages over natural tires. For example, both are less expensive and more resistant to abrasion, and also because they become harder over time, so their wear and tear is slower.
Natural tires, on the other hand, usually soften over time. In addition, there are no allergens in styrene butadiene tires and latexes, but they may be present in natural tires. In fact, the possibility of allergens in their natural tires has become a major problem for human health. People who have a lot of contact with natural rubber may have allergies to these materials, such as medical professionals who wear rubber gloves and patients who need a lot of surgery to improve. All of the above fall into the category of
similarities between the two materials, but what are the differences between them? Styrene butadiene rubber is composed of 25% styrene and 75% butadiene, which has a higher religious buta content compared to the mentioned latexes, and for this reason, its elasticity will be higher.
Latex stryene butadiene
Latex styrene butadiene is also much cheaper than alternative coatings Another use for styrene butadiene rubbers is to cover the undersides of a number of textiles, such as taffeta, which is the most popular carpet in the United States and accounts for about 90% of all types of carpets. Creating a cover for these parts allows them to be in place and have higher stability and reduce the possibility of abrasion at the edges. Styrene butadiene latexes are polymers that are widely used to produce coatings for the underside because they have high particle binding capacity and high strength. All of these are just a few uses for styrene-butadiene latexes, and new ways to apply them in different areas are being discovered at any given time. Here are a few more examples of the diversity of these latexes: the production of special coatings, adhesives and non-woven materials.
Natural rubber and white glove
One of the products made from natural rubber is white gloves, which are commonly used by medical professionals., styrene butadiene latexes have a higher mesh density compared to styrene butadiene rubbers, which makes them stronger and stiffer. This means that these items return to their normal position to a large extent after stretching and lengthening. The difference between the two is that styrene butadiene latexes and their products are much more diverse. These latexes and their processing conditions allow manufacturers to make very different polymer compounds that have distinct functional properties. One of the main uses of latex and styrene butadiene is to cover paper for products such as brochures, magazines, catalogs and cardboard products such as food cartons. These latexes increase the ability of fine-grained bonds to make paper softer, stronger, glossier, brighter and even more water resistant.
Styrene butadiene and car tire
Today, styrene butadiene tires are mostly used in the production of car tires, and about half of these tires use one of the forms of this material, but these materials are not limited to tires. Styrene butadiene rubber can be deposited in different ways, which ultimately changes its rubber compatibility. For example, when this material is processed by cold polymerization, the final product is used to fill holes in asphalt or to produce foam for mattresses. Styrene butadiene latexes are the most common type of styrene butadiene emulsion polymer, and it is important to note that these materials are not only different from styrene butadiene rubbers but also from natural rubbers. Natural latex is a white sap derived from the rubber tree, more commonly referred to as rubber trees. It is also possible to improve the composition of these juices and make them easier to process and have better physical properties.
