What is the best material for insulated cup liner

1, stainless steel: stainless steel liner is the most common insulation cup liner material on the market, with corrosion resistance, high temperature resistance, no deformation, easy to clean and so on. At the same time, the stainless steel liner has better thermal insulation properties, which can effectively maintain the water temperature. However, it should be noted that the texture of the stainless steel liner is relatively hard, easy to bump, not suitable for storing some acidic or alkaline food.

2, ceramic: ceramic liner is a relatively new insulation cup liner material, with high density, high temperature resistance, easy to clean and so on. At the same time, the ceramic liner is also able to resist the erosion of a variety of chemicals, will not release harmful substances, and therefore very suitable for drinking water. However, it should be noted that the ceramic liner has poor insulation properties, and needs to be used with a good insulation cup shell.

3, alabaster: alabaster is a traditional insulation cup liner material, with high density, high temperature resistance, not deformed and other characteristics. At the same time, alabaster liner is also able to resist the erosion of a variety of chemicals, will not release harmful substances. In addition, the thermal insulation performance of alabaster is very good, able to maintain the temperature of the water for a long time, which is very suitable for thermal insulation of hot water. However, it should be noted that the price of alabaster liner is relatively high, and at the same time, you need to avoid collision and fall.
