Connector insulation

siver/silver/teflon or silver/nickle/phenolic

bakelite - is this the same as phenolic?

polystyrene or polyethylene insulators melt when heat applied from soldering

Delrin insulating material is a little better but still can get soft at soldering temperature.

Teflon insulating material is very good and are increasingly available.

phenolic insulating material that was very good at soldering temperature.

OPINIONS FROM HAMS:

1: Don't use cheap nickel plated connectors, use PL-259 connectors which are silver plated and the connector metal is machined brass. They should also have a silver center pin. Insulator should be Teflon.

2: See the white insulator around the tip. That is teflon and will melt if you apply too much heat for too long. There are better types of PL-259 with better center insulators that won't melt so easily.
