Physical properties of some common plastic materials are indicated below. Thermoplastics. Thermoplastics can be softened as often as they are reheated and are not so rigid as thermosetting plastics but tend to be rougher.
HDPE High Density Polyethylene Able to resist deterioration, Acme's HDPE plastic products are long-lasting, resilient, and strong. HDPE plastic is an incredibly sturdy material, which has only a slightly greater density, yet a higher level of durability than low density polyethylene.
Lundell Plastics offers a variety of polyethylene sheets, including high-density polyethylene sheets. Applicable across industries, high-quality plastic is durable and able to withstand tough environments. Choose from HDPE or UHMW plastic in full or partial sheets to meet your specific needs.
Separating Plastics by Density Introduction: When plastics are recycled it is particularly important that they are separated by type. The numbers on recyclable plastics help this process along, but on a large scale it is inefficient to hand sort the items. Instead materials are separated by density.
Use our interactive properties table below to explore by property group, sort, or compare two or more plastic materials. Also, you may want to use our Plastic Material Selection Guide or Interactive Thermoplastics Triangle to assist with the material selection process based on your application requirements. For chemically resistant plastic, view our Chemical Resistance of Plastics chart.
Density measures the mass per unit volume.It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. It is important to note that density varies with temperature. Therefore, to determine the exact density of plastic, it is .
Plastic, polymeric material that has the capability of being molded or shaped. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products.
Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.. Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers, this occurs to such a degree that their actual name derives from this specific ability.

So, to help measure and compare all sorts of different materials, whether they be wood, metal, plastic, or some other form, I've complied a table of material densities from several different sources. (Various books, internet sites, and some of my own measurements.)
While you may not necessarily be able to get a full picture of how a given material will react simply from its density, it is a good start, and certainly better than a blind guess. So, to help measure and compare all sorts of different materials, whether they be wood, metal, plastic, or some other form, I've complied a table of material .
Density of Plastics Density is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm3. Specific Gravity (SG) is defined as the ratio of density of the material to the density of water (1 g/cm3) at a specified temperature. A Specific Grafity of less than 1 means that the material will float in water.
Samples of plastic are distinguished on the basis of floating or sinking in solvents of known density. Background. A tremendous variety of plastics have become commonplace in contemporary society. Unknown in 1950, plastics represent an enormous portion of …
Plastic density, shrinkage and abbreviations for common resin materials such as ABS and Nylon used with plastic injection molded parts. REQUEST A QUOTE Call: 800.735.2331
Nov 17, 2018· Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects. Due to their low cost, ease of manufacture, versatility, and imperviousness to water, plastics are used in a multitude of products of different scale, including paper clips and spacecraft.
HDPE (High-density polyethylene) is a thermoplastic derived from petroleum. It is a versatile product with low moisture absorption, excellent impact resistance, high tensile strength, and good chemical and corrosion resistance.
Professional Plastics is a leading supplier of Plastic Sheets, Plastic Rods, Plastic Tubing, Plastic Films & Precision Fabricated Plastic Parts. Our 19 locations in the USA, Singapore & Taiwan stock the widest range of engineering plastics, composites & ceramics in the industry.
High-Density Polyethylene (HDPE) is a semi flexible to hard plastic that can be easily processed by catalytic polymerization of ethylene in slurry, solution, or gas phase reactors. It is resistant to chemicals, moisture, and any sort of impact but cannot stand temperatures exceeding 160 degrees C.
Density is fundamentally a measure of weight per unit volume. Despite the general disdain of the metric system in the United States, we are quite comfortable with expressing this measurement for our plastic materials in terms of grams per cubic centimeter (g/cc). Specific gravity is a ratio and therefore is unitless. Bulk density
LLDPE (Linear Low-Density Polyethylene): Production, Price and its Properties . What is LLDPE (Linear Low- Density Polyethylene)? Linear low-density polyethylene is a kind of linear polymer which was first produced by DuPont in 1959 in Canada, with a number of short branches formed by copolymerization of ethylene with different long chains of olefins.
What is the density of plastic? This statistic outlines the density of selected plastic materials. Plastic bottle caps made with polypropylene have a density of 0.92 grams per cubic centimeter .
Obtain the piece of plastic for which you want to know the density. If the plastic object is large, it is safe to assume that the plastic is of uniform density throughout, so taking a small sample of the plastic for measurement will make things easier.
High Density Polyethylene (HDPE) High Density Polyethylene is a rigid, tough and strong resin of natural milky color. HDPE has very good stress crack resistance as well as high impact and melt strength. HDPE is appropriate for personal care, beverages, food and chemicals. It lends itself particularly well to blow molding. Polyvinyl Chloride (PVC)
Mar 25, 2014· The most simple technique however, separate the plastics by density, requires just water and salt and can be performed in your own kitchen. Some plastics have a lower density than water (e.g PP 0,92 kg/dm3) and other have a higher density (e.g. PS 1,06 kg/dm3). By cutting them in small pieces and putting them in water they separate by density.
High Density Polyethylene (HDPE) Plastics. 16 products found. Plastics are polymers used in applications ranging from packaging and parts fabrication to structural support and wear strips. These materials resist corrosion and provide electrical insulation. Plastic angle stock provides support for building applications.
Alro Plastics offers LDPE (Light Density PE), a corrosion resistant, extruded material that sustains low moisture permeability.
Mass density is an intrinsic property of matter: an object will have the same Mass Density on the Moon as it does on Earth, but it would not have the same Weight Density. Weight density plays a major role in Engineering and is the density used in the plastics industry. It …
In this article we will touch on the density of polyethylene. Much of the Global Plastic Sheeting website is dedicated to a wide variety of polyethylene such as high density polyethylene, low density polyethylene and the like. How is the density of these plastics measured? The density of polyethylene is expressed as g/cm³.
