Abstract: The present invention relates to multilayer films used to protect a surface, in particular, to such films used to protect surfaces of articles e.g., mobile electronics display protections, smartphones, tablets), industrial touch screens (e.g. machine interfaces), UV stable surfaces and glass protections for machine housings and cockpits (e.g. caterpillars, dumpers), etc.), and, more particularly, to such a multilayer protective film backed by a silicone-based pressure sensitive adhesive (PSA) and having either an aliphatic polyurethane layer or an aliphatic thermoplastic polyurethane layer on top of an aliphatic thermoplastic polyurethane layer, where the two aliphatic polyurethane layers have different physical and/or chemical properties. The present invention also relates to an article that is protected by the multilayer film as well as a method for making the multilayer protective film.

Abstract: A self-supporting energy absorbing composite includes: i) a solid foamed synthetic polymer matrix; ii) a polymer-based dilatant, different from i) distributed through the matrix and incorporated therein during manufacture of i); and iii) a fluid distributed through the matrix. In another embodiment, a self-supporting energy absorbing composite includes: iv) a solid, closed cell foam matrix; v) a polymer-based dilatant, different from i), distributed through the matrix; and vi) a fluid distributed through the matrix. In both embodiments, the combination of matrix, dilatant and fluid is such that the composite is resiliently compressible.
