Silicone Rubber Sheet,Heat Resistant, Heavy Duty,High Grade 60A,12 x 12 Inch, 1/25 Inch Thickness for DIY Gaskets, Pads, Seals, Crafts, Flooring,Cushioning of Anti-Vibration, Anti-Slip

The product works but realize it is not actually 12 by 12. it is 1/16th inch short on both length and width. Unfortunately, I needed this product to be exactly 12 by 12, being a 16th of an inch short in both directions renders it useless for my purpose. Good product but realize like others have said, its not square and its smaller than 12 by 12.

I was using this to line a mold to melt plastic into different shapes. Its kind of pricy (since I had to cut it up) But it worked good in the oven at 350F

Very flexible, good quality

This item arrived and its at best 1/16 thick .......... cant use it for my intended purpose. Disappointed ... now

Worked great for my project. As others have mentioned it’s not square.

The other one is in the trash-burned

Not good Fuel tank gasket material

Worked for what I needed. There was a hole in our RV floor where some tubes run to the outside. I used this to make a mat basically that covered the hole but let the tube through. Then glued it all down. (If the glue sticks to the silicone is another matter) but it will keep pest out so does the job.

Worked as need to cut custom rubber feet shapes.

Easy to cut, perfect for what I needed
