Methanol, also known as methyl alcohol, wood alcohol, wood naphtha or wood spirits, is a chemical produced in a catalytic industrial process directly from carbon monoxide, carbon dioxide, and hydrogen.

Methanol is the simplest alcohol. It is a light, volatile, colorless and flammable liquid with a distinctive odor very similar to that of ethanol (drinking alcohol). However, unlike ethanol, methanol is highly toxic and unfit for consumption.

At room temperature, it is a polar liquid, and is used as an antifreeze, solvent, fuel, and as a denaturant for ethanol. It is also used for producing biodiesel via transesterification reaction.

Because of its toxic properties, methanol is frequently used as a denaturant additive for ethanol manufactured for industrial uses. The largest use of methanol by far is in making other chemicals. About 40% of methanol is converted to formaldehyde, and from there into products as diverse as plastics, plywood, paints, explosives, and permanent press textiles.

Other chemical derivatives of methanol include dimethyl ether, which has replaced chlorofluorocarbons as an aerosol spray propellant, and acetic acid. Dimethyl ether (DME) also can be blended with liquefied petroleum gas (LPG) for home heating and cooking, and can be used as a diesel replacement for transportation fuel.

Methanol is used as a solvent, and as an antifreeze in pipelines and windshield washer fluid. It is also useful as an energy carrier. It is easier to store than hydrogen, burns cleaner than fossil fuels, and decomposes to water and carbon dioxide if spilled.

Linear Low Density Polyethylene (LLDPE or LDPE) and High Density Polyethylene (HDPE) are two major categories of Polyethylene (PE) or polythene that are the most common plastic. They are primarily use is in packaging (i.e plastic bag, plastic films, geomembranes, containers including bottles etc.). These plastic polymers are thermoplastic polymer consisting of long hydrocarbon chains. Polyethylene is also classified into several different sub-categories based mostly on its density and branching.

The two major categories are available from Turraco in diferent variations.

High-density polyethylene (HDPE) is defined by a density of greater or equal to 0.941 g/cm3. HDPE has a low degree of branching and thus low intermolecular forces and tensile strength. It is used in products and packaging such as milk jugs, detergent bottles, butter tubs, garbage containers and water pipes. One third of all toys are manufactured from HDPE.

Linear low-density polyethylene (LLDPE) is defined by a density range of 0.915–0.925 g/cm3. LLDPE has higher tensile strength than LDPE, it exhibits higher impact and puncture resistance than LDPE. It is used in packaging, particularly film for bags and sheets.

In copolymerization, ethylene can also be copolymerized with a wide range of other monomers and ionic composition that creates ionized free radicals. Common examples include vinyl acetate (the resulting product is ethylene-vinyl acetate copolymer, or EVA, widely used in athletic-shoe sole foams) and a variety of acrylates. Applications of acrylic copolymer include packaging and sporting goods, and superplasticizer, used for cement production.
