Silicone is a miracle product in that it’s non-porous, non-toxic, contains no BPA, BPS, PVC, lead, latex, phthalates, nitrosamines, formaldehyde, or other toxins found in petroleum-based plastics. 

It can also withstand temperatures from -58 F to 450̊ F. While you can put a Silipint in an oven, boil water in it, and microwave the heck out of it, you should not put Silipints on direct flames, a burner, or try to broil them. It’s flexible, packable, and light; you can freeze it; nuke it; throw it through the dishwasher. 

Silicone products are unbreakable and reusable, so Mother Earth loves them too. Furthermore, silicone is derived from abundant, easily accessible elements (no petroleum products that need to be drilled for). While silicone has the ability to undergo a lifetime of use, if it’s deposited in a landfill incinerator it will be broken back down into inorganic, harmless substances such as amorphous silica, carbon dioxide, and water vapor.
