Private equity investors have purchased 50% of the shares in Revolve Group, the holding company of the UK-based supplier of materials and services to the rotational moulding process, Matrix Polymers (Northampton / UK; www.matrixpolymers.com). As a result, Matrix plans to increase significantly its own capital investment and sales. Growth will be created through the purchase of additional compounding and grinding production capacity, geographical sales expansion and strategic acquisitions. In September 2005 the group announced the opening of a new colouring and grinding plant in Kolo, Poland, operated by Matrix Polymers Polska. Matrix Polymers has an annual turnover of around GBP 30m (about EUR 44.6m).
