Hollow and floating insulating polypropylene (PP) balls, BPA-free, for sous-vide devices. They create an insulating layer preventing heat loss by 75% and water evaporation by 90%. They allow water to boil for hours without needing to add more, thanks to minimal contact between water and air. They increase temperature accuracy and help keep vacuum-sealed items submerged. They reduce steam and splash risks. They withstand up to 150°C without any problem. Compatible with containers of all shapes and sizes. Comes with a practical mesh bag with a drawstring closure. - 100 hollow and floating insulating polypropylene (PP) balls, BPA-free, for sous-vide devices. - They create an insulating layer preventing heat loss by 75% and water evaporation by 90%. - They allow water to boil for hours without needing to add more, thanks to minimal contact between water and air. - They increase temperature accuracy and help keep vacuum-sealed items submerged. - They reduce steam and splash risks. - They withstand up to 150°C. - 100 balls cover surfaces of 20 cm in diameter and GN 1/3 containers. - Comes with a practical mesh bag with a drawstring closure.
