Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats to be used at home. [47] Polypropylene is widely used in ropes, distinctive because they are light enough to float in water. [48] For equal mass and construction, polypropylene rope is similar in strength to polyester rope.
Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.
Polypropylene manufacturers consume nearly two thirds of global production. [17] Polypropylene end uses include films, fibers, containers, packaging, and caps and closures. Propene is also used for the production of chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde, and acrylic acid. In the year 2013 about 85 million ...
The world's first fully synthetic plastic was Bakelite, invented in New York in 1907, by Leo Baekeland, [7] who coined the term "plastics". [8] Dozens of different types of plastics are produced today, such as polyethylene , which is widely used in product packaging , and polyvinyl chloride (PVC), used in construction and pipes because of its ...
John Paul Hogan (August 7, 1919 [1] – February 19, 2012) [2] [3] was an American research chemist. Along with Robert Banks, he discovered methods of producing polypropylene and high-density polyethylene.
The plastics industry manufactures polymer materials—commonly called plastics—and offers services in plastics important to a range of industries, including packaging, building and construction, electronics, aerospace, manufacturing and transportation.
In many real-world scenarios, a single polymer cannot meet all the demands of an application. Compound extrusion allows a blended material to be extruded, but coextrusion retains the separate materials as different layers in the extruded product, allowing appropriate placement of materials with differing properties such as oxygen permeability ...
With 36 industrial plants spread across Brazil, United States, Mexico and Germany, the company produces over 16 million tons of thermoplastic resins and other petrochemicals per year. Braskem is the world’s leading biopolymers producer with its 200,000 tons Green PE plant that produces polyethylene from sugarcane-based ethanol.
