Shellac
Shellac () is a resin secreted by the female Kerria lacca, lac bug on trees in the forests of India and Thailand. Chemically, it is mainly composed of aleuritic acid, jalaric acid, shellolic acid, and other natural waxes. It is processed and sold as dry flakes and dissolved in ethanol, alcohol to make liquid shellac, which is used as a brush-on colorant, food glazing agent, glaze and wood finish. Shellac functions as a tough natural primer (paint), primer, sanding sealant, tannin-blocker, odor-blocker, wood stain, stain, and Gloss (material appearance), high-gloss varnish. Shellac was once used in electrical applications as it possesses good electrical insulation, insulation qualities and seals out moisture. Phonograph and 78 rpm gramophone records were made of shellac until they were gradually replaced by polyvinyl chloride, vinyl. From the time shellac replaced oil and wax finishes in the 19th century, it was one of the dominant wood finishes in the western world until i ...

Synthetic Rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About of rubber is produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, seals such as O-rings and gaskets, hoses, belts, matting, and flooring. They offer a different range of physical and chemical properties which can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects: thermal stability, and resistance to oils and related compounds. They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires. History The expanded use of bicycles, and particularly their pneumatic tires, starting in the 1890s, created increased demand for rubber. In 1909, a team headed by Fritz Hofmann, working at ...

Upper Bavaria
Upper Bavaria (, ; ) is one of the seven administrative regions of Bavaria, Germany. Geography Upper Bavaria is located in the southern portion of Bavaria, and is centered on the city of Munich, both state capital and seat of the district government. Because of this, it is by far the most populous administrative division in Bavaria. It is subdivided into four planning regions (''Planungsverband''): Ingolstadt, Munich, Bayerisches Oberland (Bavarian Highland), and Südostoberbayern (South East Upper Bavaria). The name 'Upper Bavaria' refers to the relative position on the Danube and its tributaries: downstream, Upper Bavaria is followed by Lower Bavaria, then Upper Austria, and subsequently Lower Austria. It consists of 20 districts and 500 municipalities (including three cities). ''Landkreise'' (districts): * Altötting * Bad Tölz-Wolfratshausen * Berchtesgadener Land * Dachau * Ebersberg * Eichstätt * Erding * Freising * Fürstenfeldbruck * Garmisch-Partenkirchen ...

Burghausen, Altötting
Burghausen is the largest Town#Germany, town in the Altötting (district), Altötting district of Upper Bavaria in Germany. It is situated on the Salzach river, near the border with Austria. Burghausen Castle rests along a ridgeline, and is the longest castle in the world (1,051 m). History The oldest mention of Burghausen is documented in the year 1025 as Imperial real property. Emperor Conrad II, Holy Roman Emperor, Conrad II would later appoint the Counts of Burghausen as the financial administrators of the locality. But, as latest excavations have shown, the area around the main court of Burghausen's Burghausen Castle, castle has at least been inhabited since the Bronze Age. With Archaeologists finding artifacts of the pre-metal Celts, Celtic, Iron Age, and Ancient Rome, Roman era, it is hard to pinpoint a "founding" date. The town has developed over thousands of years, but it is not yet possible to say how long there has been a permanent settlement. In 1164, Duke Henry ...

Ethylene Vinyl Acetate
Ethylene-vinyl acetate (EVA), also known as poly(ethylene-vinyl acetate) (PEVA), is a copolymer of ethylene and vinyl acetate. The weight percent of vinyl acetate usually varies from 10 to 50%, with the remainder being ethylene. There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used. The EVA copolymer which is based on a low proportion of VA (approximately up to 4%) may be referred to as vinyl acetate modified polyethylene. It is a copolymer and is processed as a thermoplastic material – just like low-density polyethylene. It has some of the properties of a low-density polyethylene but increased gloss (useful for film), softness and flexibility. The material is generally considered non-toxic. The EVA copolymer which is based on a medium proportion of VA (approximately 4 to 30%) is referred to as thermoplastic ethylene-vinyl acetate copolymer and is a thermoplastic elastomer material. It is not vulcani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
