Video: ESD Flooring: Is LVT Antistatic?
April 30, 2020
Here at StaticWorx, we’ve been getting calls and emails from architects and designers who need to know – quickly – what options they have for static-control flooring for their crucial projects. There’s a lot of rush buying going on right now to equip facilities to make special medical-grade electronic parts. But quick to install isn’t the same as best to install. When you’re choosing flooring, just remember: Conductivity means something. Static generation tests and discharge tests mean something. The term low kV means nothing.

Hi, I’m Dave Long from Staticworx. Like all of you, I’m stuck inside my house right now. I thought maybe a good use of time would be to review some basics about static control, particularly as it has to do with flooring.
So what we’re going to do today is banish a myth once and for all, called the low kV carpet myth. So what I’ve done is I’ve grabbed two carpet tiles. One of them is a static-dissipative carpet tile, which has a very dark back, because it has a lot of carbon in it and the exact same style as this carpet, I have a regular carpet tile. If you notice the color of the backing is a lot lighter than the other carpet tile. These are made in the same mill. One of them is for conventional applications and one is for static-dissipative applications.
So what we’re going to do is we’re going to take my static meter, which if you look closely, it has a needle and when the needle is in the center that means there’s no static electricity. If it goes to the right, there’s a positive charge. If it goes to the left, there’s a negative charge. So I’m going to take the meter, going to set it up so all of you can see it. I’m going to charge up this metal plate, which even though it’s metal, won’t discharge to me because of this plastic handle. So you see all that static electricity that’s on the plate? So I’m going to take the plate and I’m going to touch it to this low kV carpet, conventional, commercial, low kV carpet. I think it’s two kV. Touch it. The charge didn’t go anywhere. Now I’m going to take it and I’m going to touch it to this static dissipative carpet tile. The charge is gone. Let’s do it again. This time we’ll start here. Plenty of static. Bring it here. Charge is gone.
One last thing I want to show you, there’s a rumor that certain types of LVT are low static generating. So I’m going to take the same metal plate and charge it up. And underneath my carpet tile I have a piece of LVT. This has a urethane finish, like a lot of LVT. I’m going to touch it to the LVT. The charge doesn’t go anywhere and you can see I can actually discharge it with my hand. One more thing about LVT, watch this. Not only can I not drain static electricity, but it charges objects that move on it. So don’t use LVT for static-control applications. Don’t think that because a carpet has a low kV rating that it might also be a product that can be grounded, because it can’t. Tomorrow we’ll do the same thing. We’ll meet here again and I’ll show you the electrical resistance properties of these carpet tiles. Thanks for listening.
