200 Fluid Pure Silicone Oil Polydimethylsiloxane (PDMS) 1000 centistokes (CST) Viscosity, 8oz Bottle

Silicone oil has many niche uses. Here’s mine. As a hobby, I bake latex balloons in an oven to make them softer and stretchier. I use silicone oil when baking balloons for two reasons: (1) as a heat transfer agent during the bake, similar to a traditional cooking oil, to protect a balloon from hot spots, and to distribute heat evenly over the surface of a balloon, (2) as a lubricating agent after the bake to prevent the soft and sticky rubber latex of the balloon from sticking to itself before and after inflation. Microlubrol 1,000 centistokes silicone oil works great for these two baking needs, heat distribution and lubrication. I choose a viscosity that’s more like molasses because I suspect from experience that a low viscosity oil, like 50 centistokes, will cause some premature balloon popping after inflation. My routine is to coat the inside and outside of a balloon with a light layer of silicone oil before the bake. I lay the balloon down horizontally on a layer of cheap cotton cheesecloth in a deep-dish, disposable aluminum pan at the bottom of an 18-quart electric roaster oven used for turkeys. After 10-20 minutes near the rubber melt temperature of 180°C, the balloon softens and is ready for inflation. The attached image shows a short-eared bunny balloon from ballonpoint.com after a bake. It’s twice as big as normal, but still very soft to the touch. In summary, Microlubrol silicone oil works great for me in this non-traditional usage. It’s a good product. I give it five stars.

This is excellent silicone oil, & I find myself using it for more & more jobs. Any time I need to lube some rubber, plastic, or vinyl, I reach for this. It is especially helpful when connecting Rubber Tubing, Fuel Lines, vacuum lines, etc -- makes it slide on with a LOT less effort, & the silicone will not hurt the synthetic materials. I bought a 4 ounce bottle of this, and poured it up into 1-ounce bottles so I could have some at every work bench I use. A tiny amount goes a long way, so this will last me for the rest of my life. There is also a much thinner Viscosity silicone oil available -- I use it for the synthetic seals in my piston air rifles, and for anything that needs a more "runny" lube.

The lubricant supposed to be in the package for me Schwinn Elliptical 430 was not there so I foolishly used a lubricant I had handy. After a day or two it was like moving through wet sand. Cleaned off that mess and applied MicroLubrol Silicone Oil 1000 centistokes (cst) viscosity (please note this is a thicker viscosity than lower numbers) and it was amazing. I just did a full hour on the elliptical: it nearly killed me but I did it!

Not good enough for elliptical machine replacement oil. Evaporated in a day.

Good!
