Do you know that silicone and rubber are both elastomers, even though they look the same, but both of them are different in atomic structure and show different features??
Below are some of the main difference between Natural Rubber & Silicone:
| Natural Rubber | Silicone |
| -50 °C to 80 °C | -50 °C to 230 °C |
| Excellent compression set | Excellent compression set |
| Poor weather resistance | Excellent weather resistance |
| Poor resistance to heat, chemical attacks, fungus attacks, UV and Ozone attacks | More resistance to heat, chemical attacks, fungus attacks, UV and Ozone attacks |
| Poor tensile and tear properties at high temperature | Excellent tensile and tear properties at high temperature |
Despite their differences, both of them can be found in a wide variety of products which include automotive applications, cooking, baking, and food storage products. Other than that, they also can be found at apparel such as undergarments, sportswear, and footwear. They are also can be found in electronics, medical devices & implants, and in home repair and hardware with products such as silicone sealants.
Therefore, for all Relax® products, no matter they are thermal flasks, thermal tumblers, thermal carafes or water bottles, we will be using food grade silicone straw/o ring so that our customers will feel safe when using our products.
