While plastics and glass are the main materials that make up the exterior of a television, the interior parts of a television are made up of a greater range of materials. All these materials are extracted and made in factories spread throughout the world, adding to the complexity of manufacturing televisions. Glass is the essential material that makes up the screen of a television, and is made from the chemical compound silicon oxide. Another main material that is used in most television is glass. The two are then chemically combined to make the resin-like material that is used as a thermoset. Urea formaldehyde is made by obtaining urea, a solid crystal, from ammonia gas, and by obtaining formaldehyde from methane gas. The most common thermoset used in televisions is urea formaldehyde. The fixing of thermosets is necessary for electronic appliances like televisions that produce a significant amount of heat, so that the plastic that encases the television will not melt down. The thermoset is used to fix the meltable plastic in the shape that the plastic has been molded in, meaning that once the thermoset is fixed onto the plastic, the plastic cannot be melted again. When the polyethylene is ready, it is molded into the specific shape that is required to encase a television, and is then set into that shape by using a thermoset. Ethylene is produced from the cracking of ethane gas, which can be separated from natural gas. Polyethylene is made from the polymerization of ethylene. ![]() Thermoplastics like polyethylene are used because they can be melted down and remolded repeatedly, which is part of the process in making the exterior casing of a television. One of the main types of materials used in televisions are plastics, namely thermoplastics such as polyethylene. The raw materials that are extracted for use in a television come from many different sources, which makes the beginning of the television’s life cycle one that starts at many different places. Televisions depend on a wide range of these naturally found materials to be produced, but the main kinds of materials that make up a television are secondary materials produced from the combination of various raw materials, which makes the different parts of the life cycle of a television each more complex. The materials as they are found raw in nature range from argon gas to platinum ore, and many raw materials are then combined into other secondary materials that are then assembled into the parts of the television. These materials come from many different sources, from many different areas of the world, and are all assembled into the different working parts that make up a television. As with any object made for human consumption, the television requires materials from an earth that can only provide a finite amount of such things. Over the course of the past half decade, the television has gradually become a standard American household item, to the point where it is not uncommon for a household to own more than one television.
