Kapton is the brand name of polyimide tape made popular by Dupont. The main property of this material is the ability to withstand wide temperature range without any change to its physical and electrical properties. The thermal property of the polyimide material has been well-documented during the initial days of lunar space missions as well as Man’s first landing on the Moon. Since then polyimide has been integral to space critical missions and aerospace applications.
Polyimide’s redeeming property
Reinforced polyimide films are the base of insulation systems for enhancing thermal and acoustic systems in aviation. The polymer product has a high flammability rating that is allowing aircraft manufacturers to increase fire safety due to advanced insulation properties. Fuselage burn through protection is a high priority in assessing fire risk. Reinforced polyimide film is the key in preventing onboard fire propagation. Burn through refers to containing fire in the event of a crash. Once an aircraft lands or crashes unexpectedly then the chances of aviation fuel catching fire is high. That is the reason airports are equipped with foam tenders to douse the aircraft in fire retardant foam.
Advantage of using polyimide film
Polyimide material is a high-temperature resistant material. It does not allow the fire to propagate. The film also does not ignite at high temperatures. Thus it is an excellent fire retardant film. Polyimide reinforced film is also a great solution in combating hypothermia. Television news often show victims of natural disaster with polyimide wrap around them. This first aid is widely used in most countries. Being portable the Kapton wrap solution is addressing military and community needs. The latest product comes as a bundle in a pouch and delivers about 40 degrees Centigrade of uniform heat that radiates over the victim’s back and neck. Fully charged batteries generate heat and lasts for at least 4-5 hours. The wrap is resilient even in wet conditions and at higher altitudes.
Although Kapton is in existence for nearly five decades there are only a few countries that manufacture and have expertise in the production. Research and development in the use of polyimide is a specialized subject. One of the pioneers in the field other than DuPont is the Chinese company Tianjin Tianyuan. They have a strong research background having started operations since 1970. Their understanding of the technology of polymers and applications are the cornerstone of China’s foray into space projects and aviation. As a pioneering Kapton tape suppliers from China Tianjin have the respect of their peers for producing quality polyimide tapes and films. Their pricing is competitive allowing the electronic and telecommunication industry in China to become world leaders in that space. They have set the precedence for other Kapton tape manufacturers in China to achieve excellence.
