In 1973 it was changed to the Malaysian Rubber Producers' Research Association. In 1974 the research base was relocated to Brickendonbury, Hertfordshire in a mansion which had been used for the children's television series Catweazle. In 1997 it was named the Tun Abdul Razak Laboratory by the Malaysian Prime Minister Tun Hussein Onn. Later research included work on blends of rubber and synthetics, such as nitrile, ethylene propylene rubber and Epoxidised natural rubber. The centre also worked on the performance of tyre retread compounds, showing that natural rubber-rich tyres could perform nearly as well as synthetic tyres in durability, but were more fuel efficient as they had lower rolling resistance. The centre also developed an entirely new material, thermoplastic epoxidized natural rubber. This has excellent oil-resistance and heat resistance. In 1996, it became the Tun Abdul Razak Research Centre, a wholly owned company of the Malaysian Rubber Board. The centre has various research focusses including advanced materials, products, engineering and Biotechnology. Whilst the main purpose is to support the Malaysian rubber industry, the commercial division, Rubber Consultants offers a variety of testing and other services. These include compounding, physical testing, engineering design tyre testing and analytical services.
