For this specific application we mainly advise FEP heat shrink tubing. Due to the unique properties like UV resistance and long lifetime, FEP can be used in lighting applications where high UV radiation is required. Other plastics discolour after 2-3000 burning hours and the mechanical protection is significantly reduced. Fluoroplastics have the unique property of an unlimited lifetime. FEP will therefore "survive" the lamp in many cases.
These lamps contain only a small UV content and should emit enough light as long as possible. Therefore a material with less high quality, based on Polyolefin (mix) that show a decrease in the mechanical strength and include discoloration (brownish) after 10-12000 burning hours, can be used. This is sufficient for this kind of application.
UV Stop applies mainly in applications where no bacteria growth is desired. For example algae growth in aquariums or water disinfection and/or purification. The material which can be used for these kind of applications is a Polyolefin mix with an additive which results in 10,000 burning hours, with a 100% UV-Stop.
