将近 60 年以来，TE 的Raychem瑞侃产品已经成为极端环境和条件下可靠性的代名词。此产品系列已成为材料科学、工程和制造方面的全球领先者。

原位于加利福尼亚门洛帕克的 TE's Raychem瑞侃是首家使用全新的“辐射化学”科学领域知识来开发产品的公司。 Raychem瑞侃的创始人，电气工程师 Paul Cook 发现交联的过程允许材料加热、膨胀、冷却，然后再次加热至原先尺寸，实现卓越的绝缘和保护性能，因而推出了热缩管产品。当时设计并生产了众多瑞侃产品，这些产品已在现场使用 30 年，并且正在发挥重要作用。

For almost 60 years TE's Raychem products has been synonymous with reliability in extreme environments and conditions. This family of products has been a global leader in material science, engineering, and manufacturing.

TE's Raychem, originally located in Menlo Park, California, was the first company to develop products using the new area of science called "radiation chemistry". The founder, electrical engineer Paul Cook discovered the process of cross-linking would allow the material to be heated, expanded and cooled, and then be reheated to its original size for superior insulation and protection. Resulting in the introduction of heat shrink tubing. A multitude of Raychem products were engineered and produced and have performed in the field for 30 years and counting. 

Raychem Corporation was founded in Menlo Park/Redwood City, California in 1957 by Paul Cook, James B. Meikle, and Richard W. Muchmore.

The original name of the company was RayTherm Wire and Cable and later formed a subsidiary named RayClad Tubes. The company changed names to avoid confusion with Raytheon. The company was a spin-off from SRI International, and their founding technology was wire and cable that used radiation cross-linked polymer insulation targeted at military and aerospace applications. This was the first known use of radiation chemistry for commercial products. The company soon invented heat-shrinkable tubing also targeted at electronic applications.

By 1980 the company had expanded to over 30 countries, including a major branch in Swindon, UK and made the Fortune 500 list. It was recognized as one of the fastest growing companies in the United States at that time. The company had only four CEOs until the company was acquired by Tyco International in 1999. Those CEOs were Paul Cook (Founder), Bob Halperin, (Cook's second-in-command almost from the beginning), Bob Saldich (a long-time Raychem executive, who also ran a Raychem subsidiary, RayNet) and Dick Kashnow, who was responsible for the sale of Raychem to Tyco International.

At the time of the sale the company had reached sales exceeding $2 billion and was operating in over 60 countries globally. The company invented many breakthrough technologies, including PolySwitch PPTC circuit protection devices, and the touchscreen, popular today and branded under the name Elo TouchSystems. The company's alumni now populate many CEO and president positions in a variety of industries. The major market segments where Raychem operated were aerospace and defense, automotive, telecommunications, energy networks, consumer electronics and transportation.
