GE began production under the name Lexan in 1960, creating the GE Plastics division in 1973. [29] After 1970, the original brownish polycarbonate tint was improved to "glass-clear". Polycarbonate recycling code PC on the bottom of a 5 gallon water jug made by Greif, Inc.
Dr. Daniel W. Fox and LEXAN polycarbonate Dr. Daniel W. Fox (May 14, 1927 – February 15, 1989) was an American polymer chemist who is often regarded as the father of LEXAN . LEXAN is the flagship product of SABIC Innovative Plastics (formerly GE Plastics ) and is used in everything from CDs and DVDs to car bumpers.
A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids , the conceptual anhydrides of carbonic acid , or polymers of carbon dioxide .
Dry lubricants, can be incorporated in plastics as fillers, as a component of sintered metals, or deposited on metal, ceramic and plastic surfaces. Molybdenum disulfide is a dry lubricant usable in vacuum. Tungsten disulfide is another dry lubricant usable in vacuum. It can be used at higher temperatures than MoS 2.
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
LEBC2, the Lexan bubble chamber, which had a diameter of 20 cm and was made of transparent plastic. The construction of the LExan Bubble Chamber, LEBC, was approved by the CERN Research Board on 16 November 1978. [1] Bubble chambers are similar to cloud chambers, both in application and in basic principle.
The introduction of plastics in plastic film capacitors was approximately in the following historic order: polystyrene (PS) in 1949, polyethylene terephthalate (PET/"polyester") and cellulose acetate (CA) in 1951, polycarbonate (PC/Lexan) in 1953, polytetrafluoroethylene (PTFE/Teflon) in 1954, polyparylene in 1954, polypropylene (PP) in 1954 ...
Glass-filled polymer (or glass-filled plastic), is a mouldable composite material. It comprises short glass fibers in a matrix of a polymer material. It is used to manufacture a wide range of structural components by injection or compression moulding . [ 1 ]
