Description

For paper manufacturing, sizing is the important process, the main material of sizing agent is Gum Rosin, such a process can improve water resistance, intensity and smoothness, prevent stretch & penetration of ink. With the development of chemical technology, we can have further processed rosin that called Modified Rosin for high grade paper product, the modified rosin include Hydrogenated Rosin & Maleated Rosin which can improve the stability and durability, and reduce the cost of paper production.
