Materials and Specifications 0000051762 00000 n One of the most commonly used plastics, our heavy duty acrylonitrile butadiene styrene, or ABS sheeting, has a high impact resistance and durability to be used for automotive, printing, and display applications. 0000139528 00000 n | Contact, Home Plastic Corp. carries an excellent selection of spray bottles perfect for cleaning. Because its made with long unbranched polymer chains its much stronger and thicker than PET. Excel App. Spring Design Apps Despite its many advantages and efforts made by the plastic industry to increase its reusability, PVC is still hardly recyclable and should therefore be avoided, whenever possible. Do you have a packaging idea and need some guidance on which material is best? For example, polypropylene has a density of approximately 0.90, whereas PET has a density of approximately 1.40. For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. 0000127802 00000 n 0000007137 00000 n Engineering Calculators Example: A gallon of oil weighs 9.5 lbs per gallon9.5 lbs / 8 = 1.187 specific gravity.

Hardware, Metric, ISO 0000173991 00000 n Acrylic doesn't have as much impact resistance as polycarbonate; polycarbonate's tensile strength is greater than that of PVC; PVC's heat deflection abilities are lesser than Vivak's; and so on, and so on. It has a durometer of 50 D, a tensile strength of 1600 PSI, a brittleness temperature of -76F, a specific gravity of .921, and an elongation at break. Some elements may not work properly. HDPE 0.96-0.97 First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. 0000141220 00000 n Fluids Flow Engineering Engineering Standards LLDPE 0.91-0.94 Hydraulics Pneumatics Put theplastic specific gravityin perspective! Specific Gravity means specific value of an object under normal temperature and pressure. Specific Gravity = (Weight A / Weight B) Density = (Weight A / Weight B) * 0.9976 g/cm3 There are two basic test procedures to determine the density of a material method A, used for testing solid plastics in water, and method B, used for testing solid plastics in a liquid other than water. ps = density of the fluid or substance (kg/m3) 0000176664 00000 n Structural Shapes 2023 Ji-Horng Plastic Co., Ltd.

Gears Design Engineering 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. For example, some types of plastic are reusable and others arent because of the chemicals they contain; some can be recycled and others need to be disposed of in a different way. 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. 0000004927 00000 n LDPE is used for the infamous plastic bags that are usually used for a few seconds and then discarded. We are still (just barely) within our 8-oz barrel capacity, but unfortunately Mr. Murphy is still lurking. 0000149962 00000 n Polysulphone 1.24 Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific ~P2p@0$:+mbsuz! Density of Plastics: Technical Properties. 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. WebSimply enter the density of the material in which your are interested, select the shape from the drop-down list, enter the dimensions, then hit the Calculate button. This may also be referred to as relative density. SPECIFIC GRAVITY- The ratio of the weight of Plastics have a really wide specific gravity range depending on its composition. 0000006323 00000 n 0000135948 00000 n used for pressurized water systems - sprinkler.. highly resistant to acids, bases and many solvents, resistant to a variety of acids and bases, may be damaged by some solvents and chlorinated hydrocarbons, usable for water, gas and drainage systems, similar to PVC - but designed for water up to, resistant to abrasion, acids, bases, solvents and much more.
