For more than 30 years, the Insulator Seal has created a catalog of almost 20,000 solutions for different material joints used in extreme environments. This set of solutions continues to progress as the ISI technical staff, with a combined 100 years of design experience, examines new designs every day.
Actually, more than 25% of all active projects are completely new. A total two-thirds of all products are not “standard” but have been engineered or co-developed by Insulator Seal in recent years. These applications span from pressures as low as 10-15 atm to greater than 103 atm; from temperatures as low as -269 °C to as high as 1,000 °C; from two sub-sea miles to the depths of Martian space; and from air-conditioned laboratories to down-hole petroleum drilling operations.
A representative list of materials with which Insulator Seal has experience is given below. Technology is continuously advancing; and, meeting environmental challenges can be vital to the success of customer’s design. In case materials of interest are not listed here, please contact Insulator Seal to discuss about the specific application.
