voiceofvinyl, that is exactly the thread I commented on before. It is quoting old patent applications. None of that stuff is used in the commercial industry. Look at the comments below in that thread. It is all a big joke.
The only stuff in PVC pellets is PVC and Carbon Black. If there were other additives you would be able to find 1000 threads on line about what that stuff is and you can't because I just spent an hour looking to make sure I was not FOS. You also did not read my comment on the Tergitol.
Tergitol is an alcohol! All the record cleaning companies want you to know alcohol is bad for your records so you will buy their stuff. Don't fall for it.
Cleeds, It is Mr Kirmuss who says that not me. Ultrasound is perfectly safe. Look at your stylus carefully from the side. If you have not bent your cantilever and your tonearm is parallel to the record your stylus vertical axis will be angled around 20 degrees with the tip pointed back towards the tonearm bearing. If it is not I would send it back and ask for a refund.
It is angled like that because that is the angle the cutting chisel makes.
As for the pressure a stylus exerts on the record that is simple math. You just have to know the combined area of the two contact patches. Use a weight of 2 grams then just convert the whole mess into pounds per square inch. Why don't you figure it out for us. As to whether of not vinyl goes liquid at that pressure I sort of doubt it. As you suggest friction and pressure generate heat. But I know of no infrared thermometer with resolution high enough to read the contact patch of a phonograph stylus.
At any rate the vinyl recovers and the wear rate under clean conditions is pretty slow all things considered.
