Tensile Test Plastics - Thin Sheet ASTM D882. No toxicity of the dye-coupled film was proven in all tests for biological To initially determine whether a material is thermoplastic (meltable) or thermoset (non-meltable) type, heat a metal or glass stirring rod until it glows red or orange (to about 500°F / 260°C) and press it against the sample. HDPE (High Density Polyethylene) has a density of greater or equal to 0.941 g/cm 3. This test uses a single dart configuration and a single drop height, while varying the weight of the dart. This serves both to ensure close contact of specimen and emulsion without causing pressure artifacts. H. 2)n-CH. This statistical quality assurance tool will help laboratories that want to improve and maintain a high level of performance in conducting a variety of ASTM test methods: tensile properties, propagation tear resistance (pendulum), haze . The film or sheeting may contain additives for the improvement of the surface properties, pigments, or stabilizers, or combinations thereof. The burn test involves burning a piece of plastic with a heat source such as a lighter and carefully inspecting the way it burns, the color of flame, the smell, and other characteristics. What is fascinating is how close the densities actually are to each other . However, it is designed specifically for thin sheeting and film less than 1 mm (0.04″) thick. It is commonly used in cosmetics and personal care products, food packaging materials, and medical . Polypropylene Films Properties. Hence, impact values expressed in grams cannot be normalized over a range of thicknesses without It is one of the most commonly produced plastics worldwide, with tens of millions of tons produced every year. It is available in a variety of grades and formulations to suit different needs. ASTM D882 is a common testing standard that is used to determine the tensile properties of thin plastic films and is commonly used for in-line quality control purposes.
