Is there different types of acetate which could be cut to which have better playback life or could be used for scratching? Someone told me I could get scratch friendly dubplates, which apparanty would wear like a pressed vinyl?
Is this correct?
If so which type would i be after?

there is no such thing as "more durable acetate". Acetate is per se soft. The material you have been told about is polycarbonate/lexan.

There are people on this forum specialised in that stuff. I'm sure they will drop in and share their knowledge.

cheers,

@subkontrabob: "there is no such thing as "more durable acetate" ". Well, there was. It was called a playback-lacquer to distinguish it from a mastering lacquer. They were used for demos in the old days before cassettes, and even earlier. They were more tolerant to the 20 g pickup pressure of the 1950s. They were also a bit noisier, but obviously not useless, or they would not have been used. In less professional form they were the lacquers used for home recording.
The great distinguishing mark between mastering and playback lacquers was the size: playback lacquers could make do with the traditional record sizes 10", 12", and 7", but mastering lacquers needed extra diameter.
Cut!

To add to something "old" there where 16" There is a photo of one right here posted by motorino a little while back
It was common for radio station in the usa to distribute them cut with ads announcements as well as news on them to be played on the companies radio network
In actual fact there was a company in the USA that specialised in their distribution assuring almost overnight for most major cities in the USA using air transport along with mail
Most of them dissapeared on the metal drives during the second world war
Audio devises even had a recycling service for used lacquers with a credit provided against your next purchase and they did use tro say it went to the war effort
So quite o lot of history went with them as well no doubt
Cheers
Chris
