An erosion resistant article such as rotor blades for helicopters and wind turbines having the leading edge surface protected from damage from high speed impingement of rain or sand with a protective coating formed from specific polyurethane or polyurea coating having a defined set of minimum physical properties where the protective coating can be applied as a liquid coating and cured in place or as a preformed complementary shaped covering to protect the leading edge against erosion damage in service.

The present invention relates to a film for a tire inner liner including a base film layer including a copolymer or a mixture of a polyamide-based resin and a polyether-based resin, and an adhesive layer including a resorcinol-formalin-latex (RFL)-based adhesive, and having low shrinkage rate when elongated at a high temperature and then cooled to room temperature, and a method for manufacturing the same.
