In modern industrial production, foam is a common pain point across multiple fields: slowing down production lines, reducing product quality, increasing operational costs, and even causing safety hazards. With over 40 years of proven application history, silicone-based defoamers have become a benchmark product in the field of industrial foam control. As a modern chemical enterprise integrating R&D, production and sales, Shanghai YSCHEME Chemistry Co., Ltd. adheres to the development positioning of "SRDI (Specialized, Refined, Differential and Innovative)", and has created a series of silicone-based defoamer products. With the core advantages of efficient foam control, universal adaptation and stable reliability, it provides a one-stop foam solution for various industries, helping enterprises achieve cost reduction, efficiency improvement and stable production.
The core competitiveness of silicone-based defoamers stems from the unique chemical structure of polydimethylsiloxane. Relying on cutting-edge R&D technology, Shanghai YSCHEME further amplifies product performance, forming six irreplaceable core advantages that comprehensively surpass traditional defoamers:
Wide Application Range: Polydimethylsiloxane is insoluble in both water/polar substances and hydrocarbons/organic substances, so it can be used in both aqueous and oil systems, covering almost all industrial foam control scenarios.
Low Surface Tension, High Defoaming Efficiency: The surface tension of silicone oil is only 20-21 dyne/cm, far lower than water and most foaming liquids, enabling it to quickly break foam bubbles and achieve excellent foam control effect with minimal dosage.
Excellent Thermal Stability: Common dimethyl silicone oil can withstand 150°C for long-term use and 350°C for short-term use, with its Si-O bond remaining stable, ensuring the product works reliably in a wide temperature range and adapting to high-temperature production processes.
Strong Chemical Resistance: The high stability of the Si-O bond gives silicone oil excellent chemical inertness. With a reasonable formula, it can be used normally in systems containing acids, alkalis and salts, unaffected by chemical environments.
Strong Defoaming Power with Extremely Low Dosage: It can not only effectively eliminate existing foam, but also significantly inhibit foam generation. Only 1ppm (one part per million of the foaming medium weight) is required to take effect, with a common usage range of 1-100ppm, greatly reducing usage costs and not contaminating the defoamed material.
Long-Lasting Foam Suppression: It maintains excellent foam suppression performance even in harsh environments (high pH, low pH, high temperature, high pressure), maintaining a long-term foam-free production state, indirectly reducing foam control costs and ensuring continuous and stable production.
Different industrial fields have different performance requirements for defoamers. With its diverse performance advantages, Shanghai YSCHEME silicone-based defoamers can accurately meet the differentiated needs of various industries, becoming the preferred solution for full-scenario foam control:
Resin Synthesis: Requires stable performance, cost-effectiveness and ease of use. The product ensures smooth resin synthesis without affecting product quality.
Industrial Cleaning: Demands alkali resistance, high defoaming efficiency, stability and good compatibility. It effectively eliminates foam in alkaline cleaning solutions and improves cleaning efficiency.
Water Treatment: Needs fast defoaming, stability and ease of use. It quickly removes foam in sewage treatment and water purification processes, ensuring the smooth operation of water treatment systems.
Metalworking Fluids: Requires good compatibility, long-lasting performance and filter resistance. It controls foam in cutting fluids and grinding fluids without clogging filters, protecting metal processing equipment.
Pulp Making: Needs alkali resistance, high temperature resistance and adaptability to different pulp types (softwood/hardwood). It eliminates foam in pulping and papermaking processes, improving paper quality and production efficiency.
Textile Printing and Dyeing: Requires good compatibility, stability and high temperature resistance. It controls foam in dyeing and finishing processes, ensuring uniform dyeing and product qualification.
Acrylic Emulsion Systems: Demands good compatibility with no adverse effects. It eliminates foam in emulsion production without affecting emulsion stability and performance.
Latex Systems: Requires excellent dispersibility and compatibility. It controls foam in latex production and application, ensuring smooth construction and product quality.
Food and Beverage Processing: Needs safety, high efficiency and compliance with food regulations in various countries. YSCHEME food-grade silicone defoamers meet Chinese and international food safety standards, ensuring food safety while eliminating foam.
Shanghai YSCHEME silicone-based defoamers cover a full range of product types, providing accurate selection solutions according to customers' production processes and usage scenarios to meet diverse needs:
Emulsion Type: The most widely used, featuring fast defoaming, economy and easy dispersion. Representative products such as AFE-1410/0120/1430 are suitable for most aqueous industrial scenarios and are the first choice for general use.
Improved Emulsion Defoamers: Optimized and upgraded on the basis of basic emulsion type, with improved durability, high temperature resistance, compatibility/dispersibility and acid-alkali resistance, balancing fast defoaming and long-term foam suppression, suitable for complex working conditions.
Powder Defoamers: Used in solid state, suitable for special scenarios such as dry powder products and powder processing, with convenient use and stable storage.
Concentrate: Used after dilution or emulsification, with high concentration and low transportation and storage costs, suitable for large-scale, standardized production scenarios.
Compound: Mainly used in non-aqueous systems, and can also be emulsified for aqueous systems, suitable for foam control in oil-based and non-polar systems.
Special Fluid: For special scenarios where ordinary dimethylsiloxane is not applicable, customized formulas solve foam control problems under extreme working conditions.
Silicone-based defoamers offer wide application compatibility, low surface tension, high defoaming efficiency, excellent thermal stability, strong chemical resistance, and long-lasting foam suppression performance.
