If you are to use UV sterilizer, T-Ester bottles will be the more suitable option to choose because of its high UV resistance. When using UV sterilizer with drying function, it is necessary to place the bottle body at least 1 inch (2.54cm) away from the inner wall/ceiling where the air ventilation outlet is. This may avoid any damage or deterioration of the bottle.
If your sterilization method is steam sterilizer or boiling, you may consider PPSU which has the highest heat resistance at 180°C.
If you prefer to use a UV Sterilizer as the main sterilization method to sterilize PIGEON plastic and silicone material products, you may continue to do so.
When using UV sterilizer with drying function, it is necessary to place the bottle body at least 1 inch (2.54cm) away from the inner wall/ceiling where the air ventilation outlet is. This may avoid any damage or deterioration of the bottle.
However, do note that UV Sterilization may subject the material to premature aging, especially if it is subjected to repeated sterilization. Therefore, we recommend you replace the product when it starts to discolour and/or turns cloudy.
