Isobutylene Isoprene Rubber (IIR). Butyl is a common term used for the isobutylene isoprene elastomer. As the name implies, butyl is comprised of isobutylene with a small amount of isoprene. It is known for its excellent resistance to water, steam, alkalis, and oxygenated solvents. Another outstanding characteristic is low gas permeation. Butyl is capable of providing high energy absorption (dampening) and good hot tear strength. 2, record 3, English, - butyl%20rubber

La coconisation est utilisée pour la protection, pendant un stockage prolongé, du matériel civil ou militaire non en service, de marchandises en dépôt ou de machines destinées à être expédiées par mer. Elle consiste à projeter, sur une enveloppe de tissu à très larges mailles entourant l'objet, des fibres de matière thermoplastique à l'aide d’un pistolet à air comprimé. Au moyen de solvants appropriés, on obtient, par projection, des filaments continus qui se déposent sur le tissu en réalisant un véritable cocon dont l'imperméabilité est renforcée par l'application d’un vernis. 3, record 4, French, - cocon
