The above two kinds of sound-absorbing pads (made of compact sponge or rubber) of stainless steel sinks are common in the market. But we still need to be vigilant to check this part, because some merchants may take the advantage of such a simple sound-absorbing film to increase the weight of the sink.
Why? Generally, consumers believe that the heavier the stainless steel sinks are, the more authentic the material is. Therefore, in order to cater to consumers’ buyinghabits, some businesses will use thicker sound-absorbing pads to increase the weight of their products. Many of these silencers are made of recycled materials or even scrap tires. They have no environmental certification at all, and some odors cannot even be covered by the anti-condensation coating. Over time, it will break once you pinch it with your hands. As a result, the kitchen sink gives out a pungent smell emitting from that. Don't underestimate such a small piece! A pad attached to the sink can increase the weight by at least 2 to 3 kilograms.
There are even some profit-only merchants, who in order to increase benefit by reducing the cost of stainless steel materials, use thickened silencers and coatings. Therefore, be noted that the thicker the anti-condensation coating on the back of the sink does not mean the better the quality of the sink. If a stainless steel sink is too thick, oil will collect and leak. Generally, the coating thickness from a regular factory is about 0.6 to 0.8mm.
