MATNIKS Food Grade Silicone Rubber Sheet 6x6-inch by 1/16 White [3-pack] Duro Shore A65 High Temperature Heavy Duty for Gaskets DIY Food Covers Lids Sealing Material Supports Microwave Oven Protection

These were the only food-grade silicone sheets that I found online that were more than four inches in size. They are shiny, pure white in color, and easy to cut to size.

Just as advertised and quality great for price. Worked perfect for my application.

I ordered this gasket material to seal up some containers for food storage. The product description indicates these are food grade material. When I opened the package there is a real chemical smell which concerned me . . . I thought no way do I want these near any food. But I know that producing this kind of product there are chemical compounds involved so I deccided to see if they would air out. If you separate all of sheets and lay them all out separately somewhere you'll find that they will off gas, just like the plastic and rubber parts in a new car. It takes a good few days, maybe a week or so but mine have no odor now at all. I feel if I wash them thoroughly that they are indeed safe for use for my purposes. You have to remember that they've probably been sitting on an Amazon warehouse shelf for many months, many even a year or two so the packages for sure have built up an odor.

Used it to replace gaskets on an old flip-top glass jar. Worked perfectly. Just the right thickness. Used a pair of EMT shears to cut it out but probably could have used regular scissors. Comes with a plastic “wrap” on both sides which peels off easily and came in handy when I needed to mark the pattern to cut.

I have two stove top espresso makers that have old gaskets. The gaskets are hard and brittle. No longer usable. I wanted to replace the gaskets in both pieces. I could not find pieces that were the correct size. The gaskets were either too large or too small. I did a search for food grade rubber and came across these. The plan was to make my own gaskets. I placed the order and a few days later the package arrived. I used the old gasket as a template and cut out a new one. The size was perfect and all that was left was to test out the moka pot to see how it worked. It works just fine. I have been using the coffee maker with the diy gasket made from this material. No complaints. I still need to make a gasket for the other one. The price is very good for this. I am able to make multiple gaskets of varying sizes and it will cost less than premade replacement gaskets. Very happy with the item. The rubber sheets have multiple uses. I use one as a trivet for when I take the coffee pot off the stove. Works as advertised and would not hesitate to purchase again.

I reuse plastic containers in my kitchen, and I am a backpacker. This is a terrific product to replace the gaskets in the lids of food jars and tubes. It cuts easily and can be washed in the dishwasher.

I initially bought these as well as 1/16th thickness of the same brand. These were easy to cut with a utility knife on a rotary blade mat (for cutting fabric). I was going to make gaskets out of this, but ended up not needing to use them. However, the material is so nice I know I will be able to use it one day. I cut rectangles out of one of the sheets to serve as furniture protecting buffers and I am very satisfied.

Nice firm silicone sheets.
