What role does 'TPE', listed among the wine stopper materials, play?
Although it is listed as a stainless steel product, the plastic material TPE is also indicated, which raises questions about what function it serves.
It is a safe, rubber-like plastic that gently fills the opening of the wine bottle to block air, ensuring it can be used with peace of mind even if it comes into contact with the beverage.
TPE refers to a polymer material that has soft elasticity like rubber yet is easy to process like plastic. When making 스테인레스 와인 스토퍼, rhombus lab used TPE, a food-grade plastic, alongside stainless steel[1]. Because it is difficult to completely seal the minute gaps in the opening of a glass bottle with rigid metal alone, a flexible material was added around the perimeter that goes inside the bottle to provide an airtight seal.
When you press the stopper measuring 20mm in width and 60mm in height[2] into the bottle opening, the TPE material fits softly against the inner wall of the bottle and prevents outside air from seeping in. As it is a food-grade material widely used in baby tableware with little concern over environmental hormones or harmful substances, you can use it with peace of mind even if it comes into contact with the beverage when storing leftover wine.
Whether the TPE part can be detached and washed separately has not yet been confirmed.
