To my favourite lead egroups,
I'd be very grateful if anyone could email to me or provide a webaddress for
a labelled graphic/s pointing out the lead components in a car and in a
computer. Just to give you some idea of how many lead uses that entails, I
have put together the following list and would also appreciate feedback on
its accuracy and completeness.
Regards

Uses of lead in cars and computers
Cars
· lead acid batteries

· polyurethane foam (containing 1-2% organo-lead catalyst) as
microcellular foamed polyurethanes also known as high-density urethane foams
from reaction injection moulding (RIM) used in thin section automobile trim
components such as bumper fascia; high-resilience foamed polyurethanes in
seat cushioning; flexible foamed polyurethane polymers in filters, sound
deadening layers, heat and cold insulation, fabric interlining, rug
underlays, cushioning and upholstery

· PVC in vehicle interiors eg mats; flexible bumper strips; oil and
air filters; body side moulding and mudflaps

· die cast or die cut, stamped and formed vibration and
sound-dampening and other components

· seat fabric

· metal joinery

· wheel balancing lead weights

· wheel bearings

· auto paint

· solder including radiator solder

· terne plated metal (lead plated metal) used for fuel tank lining

· auto body solder used in panel beating/body repair

· tyres/tires (lead oxide filler material)

· lubricating oil and grease

· leaded petrol/gasoline

Computers
a.. radiation shielding (including leaded glass in monitor screens)
b.. CRT (cathode ray tube)
c.. PWB (printed wiring boards)
d.. PVC coating on electrical cords & wires
e.. computer disk pack balance weights with adhesive backing
