properties of plastic

It is available in the form of solids at Room temperature. Plastic is not magnetic so it makes a good electrical insulators. Examples of synthetic polymers are polystyrene (PS), polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP) and polyvinyl chloride (PVC). There was a time when anything made of plastic was considered to be of inferior quality, but those days are past. The first synthetic (entirely manmade) plastic was produced in the early 1900s. It is easy to process, and can be blended with other polymers and/or additives, like EVA, HDPE, LLDPE, fillers, pigments to alter its basic properties. It is well-known for its ability to blend with other materials. For example, expanded PVC sheets are a foamed polyvinyl chloride material that is ideal products like kiosks, store displays, and exhibits. Properties of Plastic Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water. Plastic refers to its ability to deform without breaking. Some properties of plastics include their light weight, high resistance to various chemicals, thermal and electrical insulation and their wide range of colors, characteristics and potential … Plastics can be stretched and made into thread and woven to make fabric. There is soft and flexible plastic as well as very hard plastic that is nearly as strong as metal. What is a polymer? Plastics have revolutionized many industries for a number of different reasons to include the fact that they resist environmental degradation over time, are generally safe for human beings, are economical and widely available, and are produced with a wide variety of material properties that allow adaptation to many different applications. There are two groups of plastics, thermoplastics and thermosets. When thermoplastics are heated, there is no chemical bonding and the material’s physical properties remain unaffected. You can filter down your options by property (mechanical, electrical…), applications, conversion mode and many more dimensions. See the chart below for ABS yield strength, Young’s modulus (ABS elasticity), tensile yield strength of ABS plastic, mechanical properties of ABS plastic, and other properties. This site uses cookies. Electrical Properties: PVC is a good insulation material, thanks to its good dielectric strength. The uses of polypropylene (PP) are seemingly endless. There are thousands of patented plastics that all differ from one another. Thermosets, on the other hand, can no longer be melted down once they have been produced. This plastic database is available to all, free of charge. That malleability also increases the fabrication and production of parts and pieces. And because of the lower viscosity liquid polymers used in molding thermosets than those in molten thermoplastic polymers, RIM molding techniques can produce high impact, heat resistant, light-weight, larger, stronger, and rust and corrosion proof products like automotive bumpers and fenders, large truck and bus body parts, air spoilers, agricultural equipment, septic tanks, chlorine generation components, and much more. 2. … Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) … In the market there are so many types of models of plastics are available such as transparent, colored etc. The result is heat, corrosion, abrasion, and impact resistant material parts, which is utilized in the agricultural, aerospace, and transportation sectors, among others. It is available in fire-retardant, heat-resistant and platable grades. It is less susceptible and resistant to the kind of chemical reactions that affect metals like oxidation or rusting. Most plastics are strong, long-lasting, and lightweight. Plastic comes in all shapes and sizes. Material Properties of Plastics 1.1 Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions. Polycarbonate (PC) is the most common plastic in this category, isn’t used as much in recent years due to it being associated with bisphenol A (BPA). plastic material properties; Property Description; Coefficient of Friction : … I can demonstrate that plastics can be identified based on their physical properties, including flexibility, hardness, and density. Once formed and solidified, i.e., a process known as curing, the plastic becomes “set.” The transformation process from a liquid state to a solid state is irreversible and provides an ultra-strong end product. Synthetic polymers, which includes the large group known as plastics, came into prominence in the early twentieth century. Properties of plastic Plastic comes in all shapes and sizes. These various properties can be obtained by modifying the production process, for example by varying the temperature or pressure at which the plastic is processed or adjusting the types of monomers which are used. Properties of plastics vary depending on the chemical composition, arrangements and the processing method of its subunits. The first group, thermoplastics, become soft upon heating, which means that in principle they can be melted again and shaped in a mold. Handy list of plastic material properties and their descriptions. The chemical properties of plastics depend on the type of polymer used during the manufacturing process. The word plastic literally means ‘malleable’, meaning that you can squeeze the material into a shape and that it retains that shape after cooling. 4.
