Applications : Asbestos Replacement
For over twenty years, PVA has been successfully used all over the world as a safe replacement for asbestos. Eternit began shipping PVA fiber-reinforced roofing slates in volume beginning in 1983. This long experience in the field has provided excellent data on the longevity of PVA fibers and their suitability as an asbestos replacement.
PVA has got wide acceptance as a less hazardous and cheaper alternative to asbestos. A recently-commissioned report by the UK Health and Safety Executive concluded that PVA fibres will certainly pose a smaller risk than chrysotile as they are generally too large to be respirable and the parent material causes little or no tissue reaction. PVA fibres are being used to replace asbestos in Brazil.
