Otis Ray McIntire (24 August 1918 – 2 February 1996 [1]) was an American inventor and engineer.After graduating from the University of Kansas with a BSc degree in engineering in 1940, he went to work as a research engineer for The Dow Chemical Company. [2]
Expanded polystyrene, used for building insulation, packaging, and cup, was invented by Dow Chemical. [1] 1957: Italian firm Montecatini begin large-scale commercial production of isotactic polypropylene. 1960s: High-density polyethylene bottles introduced and soon replace glass bottles in most applications [11] 1965
Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low ...
Polythene is the world's most widespread polymer, and was first produced by ICI from 1939; many plastic bottles are made from LDPE. Polystyrene was invented in Germany in 1937. PTFE was discovered in America (New Jersey) in 1938 by Roy J. Plunkett when at DuPont. PET beverage bottles were introduced from 1973. PEEK was developed by ICI in 1977.
Its first plastic products were ethylcellulose, made in 1935, and polystyrene, made in 1937. [11] ... Dow began expanding outside of North America, ...
Also in 1954 expanded polystyrene (used for building insulation, packaging, and cups) was invented by Dow Chemical. [6] Since the 1960s, plastic production has surged with the advent of polycarbonate and HDPE, widely used in various products [ 138 ] .
Wallace Carothers invented the first synthetic rubber called neoprene in 1931, the first polyester, and went on to invent nylon, a true silk replacement, in 1935. Paul Flory was awarded the Nobel Prize in Chemistry in 1974 for his work on polymer random coil configurations in solution in the 1950s.
