Ok thanks for the info. Btw, is it the same thing for liquid nitrile rubber? Also, I see Chinese companies offering nitrile rubber sheets with a max tensile strength of only 3.1 MPa. Quality domestic companies offer nitrile sheets up to 8.7 MPa. But neither of them offer anything below 0.1mm...

Wait, so I need to layer the rubber if I want to make it myself? How do I do that? Do I just apply really thin layers over a substrate like how you would paint something? Just build up thickness slowly?

Hmm actually it might be easier to get the chemicals to make the sheets myself. But if I made my own rubber sheets, will they be just as durable as pre-made ones?

I'm not sure if that's as strong as latex film though. Or as abrasion resistant. These latex sheets have a tensile strength of 3800 PSI and 800% elongation. Would liquid latex be anywhere near that? http://www.rubbersheetroll.com/latex-rubber-film.htm Besides, I would prefer nitrile or rubber...

Hey guys, I need to get some nitrile, latex, and rubber gum sheets for a project. The problem is, I need them to be really thin - 0.1 mm or thinner. And ideally, I would like to be able to pick what color I get. I spent a few days searching the web and not even Grainger has what I'm...

nice. seems like this could really help out the case for electric cars. although recycling lithium batteries might be even more important.

Huh. I was wondering if it was possible to make a mirror that would seem 100% transparent to the naked eye, but would reflect 100% of the light of a green laser. If you stack 3 mirrors for red, green, and blue the size of a TV and put an activated carbon material designed to absorb 95% of the...

Hi guys, I'm wondering about exactly if there is some sort of range that a dichroic mirror would reflect, like a green mirror would reflect between 532nm - 600nm or something. I'm pretty sure a green dichroic mirror doesn't only reflect only 532.00000 nm and not 533 nm or something. But...

Hi guys, I was wondering if it is possible to use raw carbon fiber or fiberglass fibers without any sort of binder or adhesive epoxy in a rope or an unidirectional ribbon as long as the load is uniform, predictable, and in one direction. I think it would be less vulnerable to crack...

Why no anodizing? Well, you could try vacuum vapor deposition of all sorts of ceramic materials. Titanium Nitride, Silicon Carbide, etc. That's how they coat drill bits and cutting tools. Just remember to cover the tip somehow so it doesn't get coated. At 500C, polymers are just out of the...

You could plate titanium on the needle and then use medical titanium anodizing to make the insulating layer. You would prevent the tip from being coated by simply not submerging it in the solution along with the rest of the needle. -Gene

Hi guys, I'm trying to design a brushless motor for an EV with temperature sensing for both the copper coils in the stator and the permanent magnets in the rotor, but I'm not sure how to add a temperature sensor on the neodymium magnets in the rotor. Wouldn't the high levels of varying...

Electrostatic noise is caused by parasitic, or unintended, capacitive coupling between varying voltage sources and the signal lines. Imaging a very low value air capacitor, (less than 1pf) connected between a varying voltage source and your signal line...
