Expanded PVC sheet plastic is the ideal material where durable construction materials are needed. You can target the Engineering ToolBox by using AdWords Managed Placements. Any reliance you place on such information is therefore strictly at your ownrisk. View Cart. Though that may seem like a simple and not particularly worthwhile distinction, any engineer worth their salt will tell you that weight is of the utmost importance when deciding whether a material is appropriate for a particular project. The specific gravity of a substance is a comparison of its density to that of water. Impact Consumer Products Group All Rights Reserved 2023, 5 Highland Drive 6, Sec. i.e. Fluid.

We carry carry hose barb fittings in a variety of materials suitable for all sorts of applications. Due to the different density of plastic, we can easily identify different plastics by "Buoyancy Test", for more information, please check out in related articles. 0000145640 00000 n If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7. In 1988, theSociety of the Plastics Industryintroduced the Resin Identification Code (RIC) system which divided plastic resins into 7 different categories. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific In addition, polystyrene is not accepted incurbside collectionrecycling programs and is not separated and recycled where it is accepted. 0000143715 00000 n 0000019679 00000 n The specific gravity of a substance is a comparison of its density to that of water.

It is common to use the Over 12,000 ASTM standards operate globally, including tests specific to plastics, to help consumers have confidence that the products they purchase will perform as expected. Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected. It holds the number one spot because of its widespread utility. The tests for density and SG are particularly significant in the custom sheet industry because plastic sheet is sold on a cost per pound basis. Specially designed for marine applications, antiskid HDPE sheeting offers superior durability with the additional benefit of a non-skid surface perfect for high-traffic marine surfaces. When mixed with other substances, It can be made softer and more flexible and applied to plumbing, wiring, and electrical cable insulation and flooring. The solid wood density may be determined using the green volume, This broad range of flexible Tygon tubing products are engineered to meet many user specifications including chemical resistance, fluctuations in temperature, abrasion, high purity and long servicelife. Feedback Advertising Polypropylene is the second-most widely producedcommodity plastic and its market is forecasted to grow even more in the following years. Materials with an index between 1.53 and 1.57 are sometimes considered mid-index, while 1.58 and greater is considered high-index. The information is provided by In order to help you make better-informed decisions about the products that you buy, today we will go through the seven different types of plastic, how they differ, and their impact on the environment. This may also be referred to as relative density. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific gravity means more material per pound or varied part weight. There are two basic test procedures- Method A and Method B. The more common being Method A, can be used with sheet, rod, tube and molded articles. It comes in two basic forms: rigid and flexible. General Fax: 860-963-1998, Understanding Your Data Sheet: Density & Specific Gravity, So youve narrowed down what material you need thanks to our. Others might see it as an important way to reduce risk or liability. One of the most basic differences between varieties, however, can be found in how much they weigh. Learn more about our materials and get in touch withour sales team today! Specific gravity, generally speaking, measures the density of an object as compared to water. Portions throughout the same sample may also differ in density due to differences in crystallinity, thermal history, porosity, or changes to the material composition, such as the addition of a filler or pigment.
