摘要:
Multilayer polymeric films which may be useful for protecting the leading edges of aircraft from rain and sand erosion are presented. Typical surface protection films comprising two or more layers of a first material alternating with one or more layers of a second material, wherein the first and second materials are different materials, wherein the first and second materials comprise first and second polymers, wherein the first and second materials have a first and second Shore hardness, and wherein the first Shore hardness is greater than the second Shore hardness by more than 5 A or more typically more than 10 A.
