') Plastics can also be classified by: their various physical properties, such as: hardness, density, tensile strength, resistance to heat and glass transition temperature, and by their chemical properties, such as the organic chemistry of the polymer and its resistance and reaction to various chemical products and processes, such as: organic solvents, oxidation, and ionizing radiation. For instance, most polymers are very resistant to chemicals contained in … Unlike metals, finishes and colors can be added before fabrication and the need for certain post-treatment processes, such as painting. Introduction: Plastics come in all shapes and sizes. Gehr Plastics produces some of the finest plastic semi-finished shapes in the industry, and also some of the largest. Thermoplastics then, can be molded, melted, and remolded repeatedly into various shapes, sizes, and objects. The molecules can be fashioned with various properties depending on what we need: sticky or slippery or lightweight or soft or hard or foamy or stretchy or … well, you get the point. Contact us today to get started! They have been established to simplify standardization in the specification of plastic pipe on an international basis. Plastic, polymeric material that has the capability of being molded or shaped, usually by the application of heat and pressure. An example would be to pull on a 1" wide piece of paper that is 4" long. 2021 Osborne Industries INC. ALL Rights Reserved, Combination of Composite Materials in Design, Video: Amazing Impact Resistance of pDCPD Plastic, Video: Physical Properties of RIM Thermosetting Plastics, Lightweight with a high strength-to-weight ratio, Can be manufactured inexpensively and mass produced. It is a low-density polymer and thereby it possesses lightweight. The most commonly specified mechanical properties of polymers include stiffness and breaking stress, quantified in the table of properties and applications as flexural modulus and tensile strength. Plastics are also known as polymers. They are so named because the polymers experience a chemical change during processing to form an irreversible chemical bond when mixed and molded. There are two primary forms of plastic: thermoplastic and thermoset plastics, the use of which is dependent on the application.

font-weight: bold; Engineering Forum Thermoset plastics are polymers similar to, but generally stronger than, thermoplastics because of the polymer’s molecular cross-linking. Another important property is toughness, which is the energy absorbed by a polymer before failure—often as the result of a sudden impact. We wear plastic in our clothes—polyester (PES) and polyamides (PA) (nylons). Plastics generally possess sufficient durability, provided they offer sufficient surface … The injected resin fills all the voids in the mold, reinforces the fiber types, and forms, usually within minutes. Poly We offer LDPE products in 1-10 MIL thickness and in an extensive range of colors. Therefore, it is important to note that different types of plastics are known to possess different physical and chemical properties. Plastic is a synthetic material created from a broad range of organic polymers that have become an indispensable part of our everyday world. Engineering Book Store } The properties of plastic are numerous. Synthetic polymers, which includes the large group known as plastics, came into prominence in the early twentieth century. The size and structure of the polymers that compose different plastics contribute to the plastics’ properties. Description. The plastics that act as insulators mostly have a high dielectric strength. They are poor conductors of heat and electricity. Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure 1.1).. document.write(' ') For example, tensile properties of plastics such as plastic tensile strength and rigidity can be determined according to DIN EN ISO 527 by briefly applying load in one direction with a tensile test. Copyright © Chemical Resistance of Plastics Coefficient of Friction. Packaging and labeling, carpeting, underwear, and jackets; stationery, plastic parts and recyclable containers of all kinds; laboratory equipment, loudspeakers, and many automotive parts are made from it. There are some properties of plastic as follows: 1. 5. a To obtain specific gravity, divide … { © Copyright 2000 - 2021, by Engineers Edge, LLC www.engineersedge.com All rights reserved 1. Plastic is a synthetic material created from a broad range of organic polymers that have become an indispensable part of our everyday world. Durability. If you have a need for a quality plastic sheet or rod, in a large or unusual size, give us a try. It cannot be melted or remolded and is resistant to solvents. TYPICAL PROPERTIES of PVC and CPVC ASTM or UL test Property PVC CPVC PHYSICAL D792 Density (lb/in³) (g/cm³) 0.051 1.41 0.055 1.52 D570 Water Absorption, 24 hrs (%) 0 0.04 MECHANICAL D638 Tensile Strength (psi) 7,500 8,200 D638 Tensile Modulus (psi) 411,000 430,000 D638 Tensile Elongation at Break (%) - 27 High abrasion resistance 5. 4. 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. a To obtain specific gravity, divide density in lb/in3 by 0.0361; for density in lb/ft3, multiply lb/in3 by 1728; for g/cm3, multiply density in lb/in3 by 27.68; for kg/m3, multiply density in lb/in3 by 27,679.9. b To convert coefficient of expansion to 10-6 in/in-°C, multiply table value by 1.8. c Hardness value scales are as follows: Rm for Rockwell M scale; Rr for Rockwell R scale. Some materials up to 20" diameter and sheets up to 8" thick. Most plastics are light, chemically stable and do not rust. Downloads So, these will give good appearance to the structure and makes it attractive. Every polymer has very distinct characteristics but most share a few similar characteristics. },
