The first synthetic plastics were derived from cellulose, a substance found in plants and trees. Cellulose was heated with chemicals and resulted in a new material that was extremely durable. Thematerials for today’s plastics come from many places (some even use salt!), but most plastics can be made from the hydrocarbons that are readily available in natural gas, oil and coal.
materials of plastics Plastics are made from the following materials: Plasticizers: They improve the softening, decrease brittleness and workability of plastics.
Thematerials for plastics come from crude oil. While the term plastic describes any material one can shape or mold into any form, including some naturally occurring plastics, most of the plastics humans use today are man-made, according to HowStuffWorks.

Acrylic plastic refers to a family of synthetic, or man-made, plastic materials containing one or more derivatives of acrylic acid. The most common acrylic plastic is polymethyl methacrylate (PMMA), which is sold under the brand names of Plexiglas, Lucite, Perspex, and Crystallite.

Answer: Some fibres are called synthetic because they are not made from natural fibres. Instead, they are made by chemical processing of petrochemicals. The synthetic fibres are made up of very large units called polymers. Some of the synthetic fibres are: rayon, nylon and acrylon.
Benzene is amaterial for dyes and synthetic detergents, and benzene and toluene for isocyanates MDI and TDI used in making polyurethanes. Manufacturers use xylenes to produce plastics and synthetic fibers. Synthesis gas is a mixture of carbon monoxide and hydrogen used to make ammonia and methanol.

Instead of being recycled as new plastic bags, many bags are used to create other synthetic materials such as composite lumber. In general, plastic bags are the preferred environmental choice, not because of their recyclable qualities but because of their manufacturing process, which uses around 70 percent less energy and releases 50 percent fewer greenhouse gas particles than alternatives like paper bags.
Materials Make Plastic - Ask . Plastic materials are moldable synthetic or semi-synthetic organic solids used for a variety of purposes.
"Plastics are defined as the polymers (solid materials) which become mobile on heating and thus can be cast into moulds." Plastics are synthetic polymers which can easily be deformed.
The manufactured or synthetic plastics are often designed to mimic the properties of natural materials. Plastics, also called polymers, are produced by the conversion of natural products or by the synthesis from primary chemicals generally coming from oil, natural gas, or coal.
The familiar categories of materials called plastics, fibers, rubbers, and adhesives consist of a diverse array of synthetic and natural polymers.
