rubber

So why is it they make these pulleys with rubber in the middle of
them.i got told by a pug garage that mine was not the half rubber
pulley.it was only that some one said he will have a look for me that
he found it as i did not have time to look my self, i was to busy doing
wheel bearings on a old escort, much better to work on.

Assuming you are talking about the crankshaft pulley which drives the aux
belt, the rubber is to help damp out vibration. Those older type last for
ever, not like the newer crap they fitted to the earlier HDi engines.
