Sustainability is no longer a niche consideration but a core principle in modern manufacturing, and the paper industry is no exception. NINGBO INNO PHARMCHEM CO.,LTD. champions the use of Alkyl Ketene Dimer (AKD) wax as a key enabler of sustainable papermaking practices, primarily through its compatibility with neutral and alkaline papermaking processes.

Historically, paper sizing relied heavily on rosin-based agents, which required acidic conditions. These acidic environments led to several environmental and operational drawbacks, including increased corrosion of papermaking machinery, higher energy consumption for maintaining specific pH levels, and potential for paper degradation over time. The shift towards neutral and alkaline papermaking, facilitated by agents like AKD wax, offers significant advantages.

One of the primary benefits of using AKD wax in an alkaline environment is its synergy with alkaline fillers such as Precipitated Calcium Carbonate (PCC) and Ground Calcium Carbonate (GCC). These fillers are more cost-effective and contribute to brighter, more opaque paper. AKD sizing ensures that the paper retains its hydrophobicity and printability even in the presence of these fillers. Furthermore, operating at neutral or alkaline pH significantly reduces the corrosive effects on equipment, extending the lifespan of machinery and lowering maintenance costs. This also contributes to a safer working environment.

The reduced environmental footprint of AKD sizing extends to waste management as well. Paper produced using AKD in alkaline conditions tends to be more stable and less prone to yellowing or degradation, meaning a longer product life. Additionally, the efficiency of AKD in imparting desired properties can lead to reduced chemical usage overall. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing solutions that not only enhance paper quality but also support the industry's move towards more environmentally responsible practices. By embracing AKD wax, paper manufacturers can effectively balance performance, cost-efficiency, and ecological responsibility.
