Our cotton swab sponge is polyurethane sponge, also known as "PU" polyurethane sponge, the raw material is imported from Japan.The sponge material is divided into two kinds of Open-cell and Closed-cell.

Closed-cell sponges

The pores in Closed-cell sponges are isolated from each other and float on the water surface.Closed-cell sponge is hard, its shape will not change significantly due to the change of temperature, its size is relatively stable, and it also has stronger wear resistance.For example, CM-FS706,CM-FS707,CM-FS708, if it is a clean part that needs strong wear resistance, you can choose Closed-cell sponge.

Open-cell sponges

The Open-cell sponge will change its shape due to temperature change, shrink and deform after cooling, and its size is unstable. However, the Open-cell sponge has higher air permeability, is softer, and has strong water absorption.If you need strong water absorption, you can choose Open-cell sponge tip cotton swabs to wipe a smooth surface.
