Rubber Roller Heidelberg SM74 PM74 High Quality Offset Press Rubber Roll Stock

Product Description

The rubber type and hardness of the printing rubber roller are very important for different printing methods, and different printing requirements have different mechanical and chemical standards.

For most ordinary printing, the hardness of the printing rubber roller can reflect the quality of the rubber to a certain extent. If the hardness is too high, its corrosion resistance may be enhanced to a certain extent,

However, the ability to carry water and ink decreases, and the wear and tear on the printing machine and the graphics and text of the PS version increase. If the hardness is too small, the service life of the rubber roller may be too short due to poor compressive and corrosion resistance. For the hardness requirements of printing rollers: On the premise of ensuring good water and ink filling ability, as well as sufficient resistance to chemical corrosion and physical effects, the hardness of printing rollers should be appropriately reduced. Currently, XINBAO is providing printing machines for Heidelberg SM74 PM74 ,The hardness standard for the rubber rollers of ordinary ink printing machines is Shore A 28.

The XINBAO high-end rubber roller has a bright color from the appearance, with a delicate and smooth surface of the colloid, and a strong bonding between the glue and the core. The size of the rubber roller does not change significantly at different temperatures and can adapt to high temperature and humidity environments or harsh cold and dry climate conditions.
