The plasticity of a material is its ability to undergo some permanent deformation without … Their mechanical properties provide unique benefits to the product they are molded into. When you want to apply any type of load on a particular member, you need to know its material properties, density, etc. Another important property is toughness, which is the energy absorbed by a polymer before failure—often as the result of a sudden impact. <<91bd0c0a21c5e94eb7a02e91d1612b75>]>> data. Types of Plastics. Mechanical properties are often the most important because almost all service conditions involve a mechanical load. 4. You can filter down your options by property (mechanical, electrical…), applications, conversion mode and many more dimensions. Key Properties of ABS Plastic ABS is an ideal material of choice for various structural applications, thanks to its several physical properties such as: 0000002009 00000 n %%EOF By visiting this website, certain cookies have already been set, which you may delete and block. and cookie policy to learn more about the cookies we use and how we use your trailer 5. 0000002847 00000 n ���-��0�6�0�4�k�WV i& �0 J�� High electrical and insulation properties 4.

So we say that materials like this are strong, but not very tough. For that, in this article, I am exploring the necessary properties of polymers in a detailed manner. Recycled plastics can be blended with virgin plastic (plastic that has not been processed before) without sacrificing properties in many applications. 0000002584 00000 n 5 V. Vega, J. Clements, T.

ASTM's plastics standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives. Recycled plastics are used to make polymeric timbers for use in picnic tables, fences and outdoor playgrounds, thus providing low maintenance, no splinters products and saving natural lumber. 17 0 obj<> endobj 0000004729 00000 n Polylactic acid, or polylactide (PLA) is a thermoplastic polyester with backbone formula (C 3 H 4 O 2) n or [–C(CH 3)HC(=O)O–] n, formally obtained by condensation of lactic acid C(CH 3)(OH)HCOOH with loss of water (hence its name).
