text: The first and most important of the complementary organizations to link with Fulmer was Yarsley, whose expertise was particularly strong in plastics and polymers and their applications. The Yarsley organization was founded by Dr Victor Yarsley a pioneer expert in plastics and an entrepreneur.  Before the Second World War he had been a consultant in this new field and, starting in 1941 he had built a series of laboratories, mostly by converting and extending domestic premises, just as in the case of Fulmer. By 1970 his group consisted of Yarsley Research Laboratories (YRL) at Chessington, Surrey and Yarsley Testing Laboratories (YTL) at Ashtead, Surrey. A collaboration agreement was signed in 1970 and in 1973 Fulmer purchased Yarsley. By early 1974, most of the Chessington activities had been moved to another new building on the Stoke Poges site and the others to Ashtead.
  Also in 1973 Fulmer purchased the engineering activities of Aeon Laboratories, Englefield Green, Surrey.  Aeon's engineering work focussed on the manufacture of ancillary equipment for electron microscopes and for computers.
  In 1975 Fulmer strengthened Yarsleys plastics processing capability by acquiring IPEC (Independent Plastics Engineering Centre) of Newhaven, Sussex.  The Newhaven activities were combined with Yarsleys own plastics processing operation to form a new company: Yarsley Polymer Engineering Centre (YPEC).
  In 1977 a new site was acquired at Redhill, Surrey to accommodate YPEC and the Yarsley research and testing facilities.  This involved progressively transferring all the staff and equipment from Newhaven and Ashtead and the polymer facilities from Stoke Poges. A new company Yarsley Technical Centre Limited (YTEC) was set up to embrace all the activities carried out by YRL, YTL and YPEC.
  In 1982 Fulmer established Fulmer Research & Development (Singapore) Pte Ltd, a joint venture with the Singapore-based company Chemical Laboratories Pte Ltd. The joint venture offered metallurgical and polymer-based technical services.
  A second overseas company Fulmer Research (SA) Pty Ltd was set up in Johannesburg, South Africa in 1985. This was not successful and was closed after a few years.
