What is the effect of the elongation rate of the silicone cup lid?

Silicone cup cover are used in our lives and have a wide range. Now, these silicone products can be applied to kitchenware, or cups, or tableware. The range is getting wider and wider, indicating that the effect is better. Let's understand the silicone cup lid.

1. A variety of color options, bright colors, and customizable shapes. The body and head are made separately and then assembled together. Any style can be made by DIY.

2. Strong adsorption, the unique soft silicone material can absorb any level of glass, ceramic or stainless steel cup mouth; the whole cup can be lifted by air pressure.

3. Low carbon and environmental protection, non-toxic and tasteless, soft, non-slip, shockproof, water seepage, heat insulation, not easy to age, not easy to fade, easy to clean.

4. Silicone product manufacturers believe that silicone cup lid products are durable and effectively protect the surface of the furniture from scalds and scratches.

5. The raw material is made of 100% food-grade eco- friendly silicone, which is soft and has strong plasticity.

6. The temperature resistance range is: -40～230 degrees Celsius. It will remain soft and not deformed after baking and freezing.

7. The product meets the U.S. FDA food-grade testing standard: 21 CFR.

8. With fresh-keeping function, like a cup of juice, a cup of tea is too late to drink, and you are afraid of losing the taste, then this cup lid is very useful.

Elongation: usually refers to the "Ultimate Break Elongation" or the percentage increase relative to the original length when the sample breaks. The general elongation of hot-vulcanized solid silicone rubber ranges from 90 to 1120%. The general elongation of fluorosilicone rubber is between 159 and 699%. The general elongation of liquid silicone rubber is between 220 and 900%. Different processing methods and choice of hardener can greatly change its elongation. The elongation of silicone rubber has a lot to do with temperature.
