BTR started in 1924, when the B.F.Goodrich Company of the USA formed a UK subsidiary British Goodrich Rubber Co. Ltd. In 1934 Goodrich sold most of its shares in the company, which changed its name to the British Tyre & Rubber Co. Ltd.[1] In 1956 the company changed its name to BTR Limited, when it ceased production of tyres.[2]

The Company was dominated by Sir Owen Green from 1967 to 1993 first as managing director (until 1986) and then as chairman.[3] By 1982 BTR had acquired a large number of companies in the United Kingdom, the US, Canada, Australia, South Africa and Germany.[2] BTR acquired the Thomas Tilling group in 1983, and Dunlop Holdings plc in 1985.[4] The Dunlop road tyre business was immediately sold to Sumitomo Rubber Industries.[5] In late 1985, BTR launched a hostile take-over bid for Pilkington, a leading manufacturer of high quality glass, with operations worldwide. After a successful defensive campaign by Pilkington, BTR was forced to withdraw its offer in early 1986.[6]

BTR purchased Schlegel Corporation in late 1988 through a subsidiary. Schlegel had manufacturing facilities for door and window seals and related products in twelve countries.[7] Schlegel made automobile and building products in Europe through its subsidiaries Schlegel UK and Schlegel GmbH.[8] After the purchase BTR decided to transfer the Schlegel UK and Schlegel GmbH subsidiaries from Schlegel Corporation to itself.[7]

There was a dispute over how the transfer should be valued for tax purposes, with BTR valuing the Schlegel UK and Schlegel GmbH subsidiaries at $21,846,000 and $9,400,000, while the Internal Revenue Service valued them at $49,069,000 and $13,246,000.[8]

In 1992, Hawker Siddeley Group plc was acquired by BTR plc for £1.5bn.[9]

BTR also had an industrial products operation in Australia known as Nylex which it secured complete control of in 1995.[10]

Between 1996 and 1998, BTR sold the remaining Dunlop companies.[11] In November 1997 UniPoly S.A, bought 32 companies from BTR, including the Schlegel Sealing and Shielding Group. The acquisition cost about $867 million.[12] The deal was a management buy-out in which UniPoly Group was formed to take over most of the rubber products business of BTR plc.[13]

In 1999 BTR merged with Siebe to form BTR Siebe plc, which was renamed Invensys plc.[14][15]


The Company was latterly organised into the following businesses:[16]

  • Engineering
  • Packaging
  • Materials
  • Building products
  • Polymers
