A superhydrophobic film for coating a substrate. The superhydrophobic film comprises a plurality of nanoparticles joined together to form a continuous film, each nanoparticle having a polymer coating, wherein the ratio of average particle size of the nanoparticles to the average thickness of their polymer coatings is from 2.5:1 to 20:1. The superhydrophobic film suitably provides a durable, UV resistant coating which maintains a high water contact angle during use. A method of preparing a superhydrophobic film on a substrate is also disclosed, the method comprising admixing nanoparticles and a polymer to form nanoparticles having a polymer coating and applying the nanoparticles having a polymer coating to the substrate to form the superhydrophobic film. A formulation for coating an article with such a superhydrophobic film is also disclosed.

A flame-retardant cable having a core is disclosed. The cable contains at least one conductor and a coating made from a low smoke zero halogen flame-retardant polymer composition. The polymer composition contains a halogen free base polymer added with a) less than 170 phr of at least one metal hydroxide; b) from 1 to 10 phr of a phyllosilicate clay; c) at least 1 phr and less than 10 phr of melamine or a derivative thereof; and d) an alkali or alkaline-earth metal carbonate. The cable has improved reaction to fire performances especially in that no dripping occurs during burning, which renders it compliant with the requirements of the more recent international standards.
