Styrene Styrene, also known as ethenylbenzene, vinylbenzene, and phenylethene, is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid that evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers. Approximately 25 million tonnes (55 billion pounds) of styrene were produced in 2010.

- One of the most common chemicals in plastic cups is styrene. Styrene was added to the the USA Dept. of Health Human Services list of known carcinogens in 2011. This move was opposed by plastic manufacturers and would not have happened without quite clear proof. So, we may reasonably sure that styrene causes cancer.

- Researchers found that Styrofoam cups lose weight when in use, meaning that styrene is oozing into the foods and drinks we consume. It then ends up stored in our fatty tissue, where it can build up to levels that can cause fatigue, nervousness, difficulty sleeping, blood abnormalities, and even carcinogenic effects.

- Polystyrene Cements: This is the main type of glue used to construct plastic (styrene) models. Polystyrene cement is actually a solvent that dissolves a thin layer of the plastic model and fuses it to the adjacent piece. You actually get a weld rather than a glued joint.

- Acrylonitrile butadiene styrene, otherwise known as ABS plastic, is a lightweight material popularly used in children's toys. There are two types: one suited for extrusion molding and one for injection molding. LEGO blocks are made from ABS plastic because it is so light and durable. Keep Learning.

What Happens If You Eat Styrofoam? Styrofoam is a foam plastic that is made from styrene monomers. It is popular as an insulator in packaging and for food. There are hazardous chemicals in Styrofoam, including styrene and diethylhexyl adipate. When exposed to heat or acids, these chemicals can leach out of the Styrofoam in small amounts. This is partly why Styrofoam is not considered microwave-safe, as the plastic also breaks down easily.

Polymers: an overview One type is produced when two or more monomers are mixed and polymerized together. Depending on the reactivities of the monomers, they may form polymers with different arrangements of the monomer units (Figure 2). SBS is an example of a block co-polymer.SBS is so named with S referring to Styrene (phenylethene) and B for Buta-1,3-diene. First, phenylethene is polymerized.heir chemical properties are similar to those of simple molecules. For example, if the polymer contains a carbon-carbon double bond, as in poly(but-1,3-diene), it will undergo additions reactions with, say hydrogen or bromine.

Acrylonitrile Butadiene Styrene Acrylonitrile Butadiene Styrene, often abbreviated ABS, is the plastic used in most modern LEGO elements. Its chemical formula is (C8H8)x·(C4H6)y·(C3H3N)z, and it has melting point at about 105 °C. ABS is a thermoplastic consisting of a styrene monomer with the addition of an acrylonitrile momomer and a butadiene monomer. It is the butadiene component (a synthetic rubber mainly used in tires) that is largely responsible for the strength and impact resistance of the plastic.

Acrylonitrile butadiene styrene Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y ·(C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F).ABS is amorphous and therefore has no true melting point.ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene.BS is amorphous and therefore has no true melting point.

Lyre (August 2014) (Learn how and when to remove this template message) The lyre (Greek: λύρα, lýra) is a string instrument known for its use in Greek classical antiquity and later periods. The lyre is similar in appearance to a small harp but with distinct differences. The word comes via Latin from the Greek; the earliest reference to the word is the Mycenaean Greek ru-ra-ta-e, meaning lyrists and written in the Linear B script.

Polymer Compounding - Thermoplastic Rubber Compounds TPR: Thermoplastic Rubber. S&E Specialty Polymers is a leading manufacturer of Thermoplastic Rubber (TPR) Compounds that are available for a wide-range of applications. These compounds are formulated using Styrene-Butadiene-Styrene (SBS) or Styrene-Ethylene/Butylene-Styrene (SEBS) block co-polymers. These materials have many of the same properties as vulcanized rubbers, but can be molded and extruded using conventional thermoplastic process equipment.

- The one on the right is a newer print–only about 6 months old–but is mounted on styrene. You can see a huge difference in the smoothness of the paper, and trust me when I say that the one on the right will continue to be that smooth for years. Another great thing about styrene is you can stand up your photos!
