Sulfur at harbor in North Vancouver, British Columbia, ready to be loaded onto a ship Latex being collected from a tapped rubber tree. A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products.
The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered.
reinforcement of composite materials (glass-reinforced plastic, glass fiber reinforced concrete) specialty papers in battery separators and filtration; Metallic fiber (1946) is used for: adding metallic properties to clothing for the purpose of fashion (usually made with composite plastic and metal foils) elimination and prevention of static ...
Manufacturing provides important material support for national infrastructure and also for national defense. On the other hand, most manufacturing processes may involve significant social and environmental costs. The clean-up costs of hazardous waste, for example, may outweigh the benefits of a product that creates it. Hazardous materials may ...
Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis. In industry, materials are inputs to manufacturing processes to produce products or more complex materials. [1]

For example, since 2010 over US$200 billion has been invested in the United States in new plastic and chemical plants, stimulated by the low cost of raw materials. In the European Union (EU), too, heavy investments have been made in the plastics industry, which employs over 1.6 million people with a turnover of more than 360 billion euros per year.
Following the example above, if one had a composite material made up of α and β phases under isostress conditions as shown in the figure to the right, the composition Young's modulus would be: = / (+) The isostrain condition implies that under an applied load, both phases experience the same strain but will feel different stress ...
