PRODUCT INTRODUCTION
Defoamer & Dispersant for Papermaking is a high-performance papermaking auxiliary designed to control foam formation, suppress foam accumulation, improve fiber/filler dispersion, stabilize slurry system and enhance machine runnability in paper and board production.
This product is widely used in paper machines, pulp preparation, black liquor treatment, white water recovery, paper forming and board production. It provides foam control, good dispersion, good stability, easy use, non-hazardous property and good compatibility.
Our papermaking defoamer and dispersant is produced under strict process control. It is available in different grades according to pulp type, paper grade, foam level, slurry condition, pH range, machine speed and application system. Each batch is inspected for appearance, solid content, viscosity, surface tension, defoaming performance, dispersion performance and stability before shipment.
We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and dosage according to your papermaking system, machine condition and destination country regulations.

Formula Guidance:
Use PDD-100 for general systems, PDD-200 for high foam systems, PDD-300 for black liquor treatment, PDD-400 for high speed machines, PDD-500 for recycled fiber and PDD-600 for board. The dosage should be confirmed by defoaming test and production result.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Insufficient Foam Control
Unsuitable grade, insufficient dosage, wrong pH or high foam source causes poor foam control.
Solution: Select suitable grade, increase dosage, control pH and reduce foam source.
Poor Dispersion Performance
Unsuitable grade, insufficient dosage or wrong formulation causes poor dispersion.
Solution: Use high performance grade, increase dosage and optimize formulation.
Foam Rebound Problem
Unsuitable grade, short foam inhibition time or wrong adding point causes foam rebound.
Solution: Use high foam inhibition grade, extend action time and optimize adding point.
System Buildup and Scaling
Unsuitable grade, high polymer or wrong pH causes system buildup.
Solution: Reduce polymer dosage, control pH and select compatible grade.
Poor Compatibility with Additives
Wrong grade or incompatible additive causes precipitation or poor performance.
Solution: Test compatibility before production and select matching grade.
Uneven Foam Control Result
Poor mixing, uneven distribution or wrong adding point causes uneven result.
Solution: Improve mixing condition, optimize adding point and ensure uniform distribution.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
High COD Load in Wastewater
High organic content or excessive dosage increases wastewater treatment load.
Solution: Optimize dosage, use concentrated grade and cooperate with wastewater treatment.
