Functional additives are chemical agents that impart special properties to the process and the final product during pulping and papermaking, with significant effects.

1. Defoamer

Higher alcohol defoamers,

complex alcohol defoamers,

polyether defoamers,

polyether ester defoamers,

silicone defoamers,

mineral oil defoamers,

silicone-polyether compound defoamers.

Foam issues have long been a persistent challenge in pulp and paper production processes. They often lead to reduced dewatering efficiency on the wire, decreased washer efficiency, increased conductivity, further limiting production capacity, and even causing product quality degradation. Foam overflow also leads to poor site conditions and increased safety hazards. Therefore, the correct use of defoamers is crucial. Customers can directly choose the appropriate product type based on their actual mill conditions, and our professional engineers will assist in recommending the corresponding product model.

2. Retention Aids, Drainage Aids, Sizing Agents

Retention and sizing are two fundamental steps in the papermaking process, playing a crucial role in controlling production and imparting properties to the paper.
