　　Rubber rollers are divided into polyurethane rubber rollers and silicone rubber rollers, and silicone rubber rollers are further divided into solid silicone rubber rollers and liquid silicone rubber rollers. The difference of various materials also shows that the processing technology of each added material is different.

　　There are many types and different uses of rubber roller products. There are rubber rollers for lamination, thermal transfer, anti-static, and dust and dust removal. Each type of rubber roller has different performance requirements for silicone, so how to judge the quality of the rubber roller?

　　To make a rubber roller with liquid silicone, the first thing to do is to choose the right hardness. Generally, rubber rollers from 0 degrees to 60 degrees can be used. The lower the hardness of the liquid silicone, the more likely the surface of the cured rubber roller will be sticky and dry. If the surface of the rubber roller is sticky and dry, it will easily lead to traces and lines on the surface of the pressed product, which is not up to the standard.

　　The dust-removing and sticky rubber roller is a special requirement that the surface of the rubber roller has a unique viscosity after curing. This viscosity is similar to the viscosity of tape, which can well remove the dust and particles on the surface of the product. The liquid silica gel used to make the dust-sticking rubber roller needs to be added with special additives during the production and preparation of the silica gel to achieve the effect of sticking dust.

　　The last requirement is that the rubber roller made of liquid silicone can be wear-resistant, aging-resistant and high-temperature resistant. Many liquid silicone rubber rollers work in a high temperature environment, or are often exposed to corrosive solvents. In this complex and changeable environment, silicone rubber rollers are required to have good performance. Generally, the rubber roller made of two-component addition silicone has higher performance. The two-component addition silicone can withstand high temperature of 200-300 degrees, acid and alkali resistance and aging resistance.
