PolyOne Corporation
Avient Corporation is a global manufacturer of specialized polymer materials headquartered in Avon Lake, Ohio. Its products include thermoplastic compounds, plastic colorants and additives, thermoplastic resins, vinyl resins, thermoplastic composites and specialty thermoset composite materials. History PolyOne was formed on August 31, 2000 from the consolidation of The Geon Company (Geon) and M.A. Hanna Company (Hanna). The merger between M.A. Hanna Company and The Geon Company in 2000 produced PolyOne Corporation. In 2009, PolyOne was ranked #731 on the Fortune 1000 list and included in the S&P 600 investment index. Hanna was formed in 1885 as a privately held company focused on mining and shipping and became publicly held in 1927. In the mid-1980s, Hanna began to divest its historic mining and shipping businesses to focus on polymers. Hanna purchased its first polymer company in 1986. Geon’s roots date back to 1927 when BFGoodrich scientist Waldo Semon produced the first u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Avon Lake, Ohio
Avon Lake is a city in northeastern Lorain County, Ohio, United States, located on the southern shore of Lake Erie about 17 miles west of Cleveland. The population was 25,206 at the 2020 Census. It is part of the Cleveland metropolitan area. History Avon Lake was first settled in the 17th century and was, along with Avon, Bay Village, and Westlake, inhabited by the Erie. After the war with the Iroquois in 1656 ended the peoples were largely dispersed or integrated into Iroquois society. The area was then sparsely populated until the Lenape and Wyandot migrated into the area in 1700. The first European settlement in the area was founded in 1786 by Moravian missionaries. The Northwest Indian war resulted in the Indians in the area giving up all land East of Cuyahoga river in the Treaty of Greenville. Undoubtedly this was the start of European contact with the peoples in Avon lake, who now found themselves in the Connecticut Western Reserve. Any remaining Indian claims to their ...

Polymer
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermoplastic
A thermoplastic, or thermosoft plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a viscous liquid. In this state, thermoplastics may be reshaped and are typically used to produce parts by various polymer processing techniques such as injection molding, compression molding, calendering, and extrusion. Thermoplastics differ from thermosetting polymers (or "thermosets"), which form irreversible chemical bonds during the curing process. Thermosets do not melt when heated, but typically decompose and do not reform upon cooling. Above its glass transition temperature and below its melting point, the physical properties of a thermoplastic change drastically without an associated phase change. Some thermoplastics do not fully crystallize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Colorant
Plastic colorants are chemical compounds used to color plastic. Those compounds come in a form of dyes and pigments. The type of a colorant is chosen based on the type of a polymeric resin, that needs to be colored. Dyes are usually used with polycarbonates, polystyrene and acrylic polymers. Pigments are better suited for use with polyolefins. The colorant must satisfy various constraints, for example, the compound must be chemically compatible with the base resin, be a suitable match with a color standard (see e.g. International Color Consortium), be chemically stable, which in this case means being able to survive the stresses and processing temperature (heat stability) in the fabrication process and be durable enough to match the life duration of the product. The parameters of the compound vary with a desired effect, which may include the final product being pearlescent, metallic, fluorescent, phosphorescent, thermochromic or photochromic. The exact chemical formula will fur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Additive
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

BFGoodrich
BFGoodrich is an American tire company. Originally part of the industrial conglomerate Goodrich Corporation, it was acquired in 1990 (along with Uniroyal, then The Uniroyal Goodrich Tire Company) by the French tire maker Michelin. BFGoodrich was the first American tire manufacturer to make radial tires. It made tires for the then new Winton car from Winton Motor Carriage Company. BFGoodrich tires have been fitted to several noteworthy historical vehicles: * In 1903 the first car to cross the United States was fitted with BFGoodrich tires. * In 1927 Charles Lindbergh's airplane, the "Spirit of St. Louis," which made the first successful solo non-stop flight across the Atlantic, was fitted with BFGoodrich tires. * The Space Shuttle Columbia's landing gear was fitted with BFGoodrich tires. BFGoodrich has been involved in several Baja California Competitions and enjoyed success with 28 overall victories at the Baja 1000 and 13 times winner of the Paris–Dakar Rally. History ...

Waldo Semon
Waldo Lonsbury Semon (September 10, 1898 – May 26, 1999) was an American inventor born in Demopolis, Alabama. He is credited with inventing methods for making polyvinyl chloride useful. Biography He was born on September 10, 1898. Semon is best known for inventing vinyl, the world's third most used plastic. He is also credited for being the first to commercialise plasticizers for vinyl, which greatly increased their utility, starting with dibutyl phthalate. He found the formula for vinyl by mixing a few synthetic polymers, and the result was a substance that was elastic, but wasn't adhesive. Semon worked on methods of improving rubber, and eventually developed a synthetic substitute. On December 11, 1935, he created ''Koroseal'' from salt, coke and limestone, a polymer that could be made in any consistency. Semon made more than 5,000 other synthetic rubber compounds, achieving success with ''Ameripol'' (AMERican POLymer) in 1940 for the B.F. Goodrich company. In all, ...
