Plastics Compressive Strength Testing
Abstract: Compression test is a mechanical test that determines how much compressive force a material to resist before cracking. A gradually applied load compresses the test item, which is commonly in the shape of a square, pyramid, or cylinder, between the platens of a compression-testing machine. Many ductile metals, such as mild steel, have extremely high compression strength, yet measuring them is challenging. Whenever a load is given to a ductile …

A Critical Evaluation of Polypropylene Impact Copolymer Morphology
Abstract: In order to improve Polypropylene (PP) impact strength, the process of copolymerizing propylene with ethylene is being used. Polypropylene copolymer is essentially a rubber-toughened material consisting of polypropylene homo-polymer matrix in which ethylene-propylene rubber (EPR) is distributed. The overall impact behavior of the copolymer is solely controlled by the rubber morphology and its distribution in polypropylene matrix, which plays a critical role on crystallinity. Even a similar impact grade polypropylene …
