This Widnes firm was formed in 2009, when management team Mark Stewart, 59, Dominic Barrow, 49, and David Hall, 54, bought out two UK divisions of American plastics giant PolyOne. The firm specialises in making plastisols — liquid suspensions of PVC or acrylic — used in the manufacture of everything from fishing tackle to flooring. It also makes Pantone pigment dispersions for paints and inks. International sales hit £4.9m last year, with exports to Europe accounting for 95%.
