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 .

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 ...
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.
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 ]
