Description Raychem Thermofit 3-piece Kit, c. 1957-1999. Seven sets contain three pieces each. One Thermofit tube (A) is made of Polyolefin plastic. Tube is black with white writing and is four inches long. One clear tube (B) made of Polyvinylidene Fluoride plastic has black writing. Clear tube is three inches long. Final piece is a set of marker strips (C) made of Polyolefin plastic. Seven evenly spaced strips horizontal stripes are attached to one long vertical strip. The whole piece is made of clear plastic, but the smaller horizontal strips have additional white plastic sleeves. White sleeves cover most of clear plastic and have black writing. All three pieces (A, B and C) are stored in rectangular clear plastic bags.

The Wire Markers are sleeves which can be printed on to label wires. After printing the desired label or text onto the sleeve, it is slipped on a wire and a heat gun is used used to shrink it on.

"Raychem was founded on January 1, 1957. It grew rapidly by creating proprietary new products based on Radiation processing of polymers to meet critical and difficult industry needs for electrical circuit integrity in harsh environments. Included in these initial products were irradiated wire insulation and heat shrinkable tubing. Markets included Aerospace, Military, Automotive, Telecommunications and Electrical Power Generation markets.
"In 1968, Raychem acquired Chemelex leading Raychem to extend its radiation polymer processing technology to polymers filled with conductive carbon creating a family of "Self Limiting Heaters". This technology was further extended to produce resettable switches forming the enabling technology for the "Polyswitch" Division.
"As Raychem grew into a world class Material Science Company, additional technologies explored, developed and taken to market were Heat Recoverable Metals, Piezoelectric Materials (Elographics), Silicone Gels (Geltek) and Liquid Crystals (Taliq).
"Each year, Raychem devoted between 8 and 10 percent of sales into Research and Development resulting in thousands of new products based on the technologies listed above. Research and Product Development labaratories, in addition to Menlo Park and Redwood City were established in Swindon, UK, Kessel-Lo, Belgium, Ottobrunn, Germany, Pontois, France and Japan.
"Manning these laboratories were an extremely creative and talented group of scientists and engineers who found innovative ways to use technologies to create new products."
