The Raychem Corporation was founded and headquartered in Menlo Park, California, in 1957 by Paul M. Cook, James B. Meikle, and Richard W. Muchmore. [1] Led by Cook and second-in-command Robert M. Halperin, Raychem became a pioneer of commercial products realized through radiation chemistry.
Wrapped optical fibre cable technology was developed independently in the UK and Japan in the early 1980s. In the UK, Raychem Ltd had a background in polymeric materials with resistance to high voltage environments; used for example in heat-shrinkable 33kV cable terminations and in polymer insulators.

The first commercial thermoplastic LSZH material for cable jacketing was invented by Richard Skipper in 1979 and patented by Raychem Corporation. [2] This invention resolved the challenge of incorporating sufficient inorganic filler, aluminium trihydrate (ALTH), into an appropriate thermoplastic matrix to suppress the fire and allow a char to be formed, which reduced emission of poisonous ...
It manufactures cable accessories up to 245 kV, and connector systems, viz. shear bolt, low power-loss wedge connectors, insulation piercing, deep step indentation, and bolted, up to 1200kV. Raychem Zero-Halogen Heat-shrink technology is widely used in Metro underground applications.
In 1962, the business was incorporated in Massachusetts and refocused on high-tech materials science and energy conservation products. Two years later in 1964, the company went public and began to fill gaps in its development and distribution network by acquiring Mule Battery Products, the first of Tyco's 16 acquisitions in the next four years.

It was first produced in the late 1960s or early 1970s by the Raychem Corporation under the trade name CryoFit. Manufacture of these couplings for aerospace hydraulic connections was later transferred to AMCI (Advanced Metal Components Inc.) and then later to Aerofit Products Inc. Additional products using the same shape-memory alloy technology ...
