HC Deb 18 July 1973 vol 860 c164W
Dame Patricia Hornsby-Smith

asked the Secretary of State for Trade and Industry if he will institute an investigation into the increasing replacement of metal by plastic working components in electrical appliances, in order that assessment may be made as to whether the initial saving is offset by speedier deterioration, increasing repairs and more frequent renewal.

Mr. Anthony Grant

Plastic components have greater insultating qualities and do not corrode, compared with their metal counterparts. There is no evidence of speedier deterioration or more frequent repairs which would justify any investigation.
