Because silicone oil is super slippery and minimally reactive it can lubricate most anything.
Plastic on plastic lubricant.
Table 1 gives general compatibility guidelines.
Some plastic gears can be embedded with lubricating materials such as ptfe silicone or graphite.
Tips for lubricating plastic parts quick overview lubricants improve the performance and life of gears bearings slides and other plastic parts if they are formulated specifically for lubricating plastic components.
This quick study contains tips that will help you choose the best lubricant for your plastic part with special notes on gears.
Lubricants are used in plastics mainly to reduce friction between the processing machinery and the plastic materials.
However plastics are a special case for two reasons.
Another reason which may not be apparent is the reduction of friction between the molecules of the plastic materials.
It works especially well on porous items such as plastic parts but is a good lubricant on locks hinges and guns.
As with all things silicone has its dark side.
Machinery parts and components made from plastic can be an easier and more cost effective alternative to traditional metal parts for some applications.
