Sponge sandpaper is a type of sandpaper. Compared to general sandpaper, sponge sandpaper does not use paper or cloth as the abrasive carrier, but instead plants the abrasive on the sponge or TPU. This is the main difference between sponge sandpaper and general sandpaper. In addition, the two have the following differences:


1. Generally, sandpaper is often used to polish rough surfaces, while sponge sandpaper is more suitable for surface grinding.


2. Generally, sandpaper is in the form of sheets, while sponge sandpaper can be made into various shapes and specifications.


General sandpaper is usually milled, while sponge sandpaper can absorb water and has good water resistance. It can be ground dry or wet.


With the creation and use of sponge sandpaper, more and more occasions are starting to use it. Can sponge sandpaper replace sandpaper?


Sponge sandpaper, like ordinary paper sandpaper, has a layer of abrasive planted on the paper, and another layer of abrasive planted on the sponge or TPU. It can be said that sponge sandpaper is an upgraded and advanced product of ordinary sandpaper. Relatively speaking, sponge sandpaper is more durable, softer, and has a better draft than ordinary sandpaper. Moreover, because sandpaper is made of sponge, it has a very good pressure feeling during polishing, and the force will be very uniform, Although the polishing efficiency is similar to that of regular paper sandpaper, it feels better when polishing than paper sandpaper, and sponge sandpaper of the same thickness is more evenly polished than regular sandpaper.


The biggest advantage of sponge sandpaper is that its surface treatment effect is superior to that of ordinary sandpaper under the same abrasive and particle size. At coarser particle sizes, sponge sandpaper has a higher cutting and durability than traditional sandpaper.


Therefore, overall, sponge sandpaper is better than general sandpaper and can replace general sandpaper. However, sponge sandpaper has a higher cost compared to general sandpaper. Therefore, it is mainly used for manual polishing of furniture, surface polishing of plastic products, polishing of car repair paint areas, surface treatment of metal rust spots and plastic, and other areas with high polishing requirements. Generally, sandpaper is still more economical and cost-effective for general polishing. Both have advantages and can be selected based on actual usage needs.
