W. L. Gore & Associates, Inc.

A privately held company with $3.5 billion in annual revenues, W. L. Gore & Associates (Gore) pursues opportunities where our core technologies and deep technical expertise make a meaningful impact. Gore delivers breakthrough solutions to product and process challenges in a variety of markets and industries — from aerospace to pharmaceutical to mobile electronics, and more. The wide range of Gore products includes hook-up wire to power challenging systems in military aircraft and downhole tools, navigation and communication cables for missions to Mars, fuel cell components that enable cleaner, greener transportation and power generation, venting solutions to manage the internal pressure in mobile electronics and automotive components enclosures, and cable integrity technologies for 5G applications. Our specialized medical devices treat a range of cardiovascular and other health conditions.

Gore has 9,500 Associates, with manufacturing facilities in the United States, Germany, United Kingdom, Japan and China, and sales offices around the world.

In 1958, Bill and Vieve Gore launched W. L. Gore & Associates in the basement of their Delaware home to explore the untapped potential of the polymer polytetrafluoroethylene, or PTFE. The company's first product was MULTI-TET™ Insulated Wire and Cable. It was used most widely in defense applications and in the burgeoning computer industry. In the 1960s, the company's first patent was issued and Gore's technology landed on the moon as part of NASA's historic Apollo 11 mission.

In 1969, the couple's son, Bob Gore, discovered how to modify PTFE to form a strong, porous material. This invention —expanded PTFE or ePTFE — changed the future of the enterprise and paved the way for waterproof, breathable GORE-TEX® fabric and thousands of diverse innovations.

As the company that invented ePTFE and introduced it in the marketplace, Gore remains a fluoropolymer leader, committed to engineering excellence and building on our founders' tradition of using advanced materials to improve lives and change outcomes for customers and end users around the world.

GORE™ High Temperature Capacitors are primarily used as DC-Link capacitors in challenging power electronic applications. Unlike other polymer film capacitors which typically are limited to 120°C operating temperature, GORE™ Capacitors have proven capable up to 250°C. With the introduction of wide bandgap semiconductors (SiC and GAN), the lack of suitable high temperature capacitors has become an increasingly difficult challenge for system designers. Designers are faced with adding significant design complexity or limiting system performance to prevent the capacitors from overheating. GORE™ High Temperature Capacitors will allow designers to significantly improve the total system efficiency and allow film capacitors, known for reliability, to be used in applications not possible in the past.

GORE™ High Temperature Capacitors are gaining widespread commercial use in oil and gas downhole tools with the major global oilfield service companies. Additionally, several leading aerospace design companies are qualifying GORE™ High Temperature Capacitors for multiple commercial and defense applications supporting more electric aircraft (MEA) and future all-electric aircraft programs.  With the electrification mega-trend, further adoption will only accelerate as additional complementary technologies are advanced and new systems are qualified.
