Ethylidene Norbornene (ENB) is generally manufactured from a reaction of two other chemicals (cyclopentadiene and 1,3 Butadiene) in a chemical plant.
EPDM rubber is used in wide variety of applications, ranging from motor vehicles to food containers
At ambient temperature and pressure, ENB is a colorless liquid with an extremely strong odor.
The flash point for ENB is approximately 30-40ºC.
Ethylidene Norbornene has a Fast cure, good tensile strength

Calcium silicate (often referred to by its shortened trade name Cal-Sil or Calsil) is the chemical compound Ca2SiO4, also known as calcium orthosilicate and sometimes formulated 2CaO.SiO2.
It is one of group of compounds obtained by reacting calcium oxide and silica in various ratios.
Calcium silicate is commonly used as a safe alternative to asbestos for high temperature insulation materials. Industrial grade piping and equipment insulation is often fabricated from calcium silicate.

Theoretically, there are three structural forms of polystyrene that can be prepared from styrene monomer: atactic (phenyl rings randomly oriented about the polymer chain), syndiotactic (phenyl rings on alternating sides about the polymer chain), and isotactic (phenyl rings all on one side of the polymer chain).
Syndiotactic polystyrene (SPS) is a new form of polystyrene polymer first synthesized in 1985 according to the claims of Idemitsu.

Pterostilbene is a stilbenoid chemically related to resveratrol and is found in blueberries and grapes.
It belongs to the group of phytoalexins, agents produced by plants to fight infections
pterostilbene, a compound in the berries, may prove to be a potent weapon in the battle against heart disease
Pterostilbene has advantages over resveratrol: superior biological activity, better oral bioavailability, and slower metabolism in the body.
pTeroWhite® is a skin care active based on pterostilbene that is said to have antioxidant, anti-inflammatory and skin-lightening properties
Pterostilbene has been shown to have diverse pharmocological actions including a cholesterol lowering effect, enhanced insulin sensitivity, calorie restriction and increased life span

Anthocyanidins are common plant pigments. They are the sugar-free counterparts of anthocyanins based on the flavylium ion or 2-phenylchromenylium, which is a type of oxonium ion (chromenylium is referred also to as benzopyrylium).[1] They form a large group of polymethine dye.
In particular anthocyanidins are salt derivatives of the 2-phenylchromenylium cation, also known as flavylium cation.
Anthocyanidins have flavylium cations, a lewis acid will interact with buckminsterfullerence which is a resonance and canonical structure as lewis basis.
Among polyphenols, the anthocyanidins and their glycosylated derivatives, anthocyanins, abundantly present in pigmented fruits and vegetables.

The cephalosporins are a class of ß-lactam antibiotics originally derived from the fungus Acremonium, which was previously known as "Cephalosporium".
Together with cephamycins they constitute a subgroup of ß-lactam antibiotics called cephems.
Cephalosporins are indicated for the prophylaxis and treatment of infections caused by bacteria susceptible to this particular form of antibiotic.

Hydrogen cyanide (with the historical common name of Prussic acid) is a chemical compound with chemical formula HCN.
It is a colorless, extremely poisonous liquid that boils slightly above room temperature at 26 °C (79 °F).
Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen.
A solution of hydrogen cyanide in water is called hydrocyanic acid. The salts of hydrogen cyanide are known as cyanides.
An electrochemical measuring cell for detecting hydrogen cyanide by means of at least one measuring electrode and a counter electrode disposed in an electrolyte.

Lithium titanate (full name lithium metatitanate) is a compound containing lithium and titanium.
It is an off-white powder at room temperature and has the chemical formula Li2TiO3.
It is the anode component of the fast recharging Lithium-titanate battery.
It is also used as an additive in porcelain enamels and ceramic insulating bodies based on titanates. It is preferred as a flux due to its stability.
The lithium-titanate battery is currently being used in battery electric vehicles and computer batteries.
Uses in Sintering :-The sintering process is taking a metal powder, putting it into a mold and heating it to below its melting point.

Catechol, also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C6H4(OH)2.
It is the ortho isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts. About 20 million kg are produced annually, mainly as a precursor to pesticides, flavors, and fragrances.
Catechol occurs as feathery white crystals that are very rapidly soluble in water.
Catechol is produced industrially by the hydroxylation of phenol using hydrogen peroxide.
Previously, catechol has been produced by hydrolysis of 2-substituted phenols, especially 2-chlorophenol, with hot aqueous solutions containing alkali metal hydroxides. Its methyl ether derivative, guaiacol, converts to catechol via hydrolysis of the CH3-O bond as promoted by hydriodic acid.
