|Description||Raychem Chemelex Auto-Trace Heating Cord, c. 1957-1999. Black plastic cord is flat with rounded edges. Edges are raised and middle of cord is flat and inset. One end of the cord has a two pronged black plastic plug. Prongs are brass. Plug has embossed vertical lines around edge closest to prongs and two embossed triangles running end to end. Between two prongs is a piece of green plastic reading, "REMOVE". The other end of the cord a plastic piece, which appears to be melted on the end. Plastic piece has slightly rounded neck attaching to cord and a flat, rounded end with horizontal lines embossed. The product name and description are printed in white ink at intervals along the cord's length. Cord is coiled with piece of masking tape holding it together.|

"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."
