Addovate 390 is a specialized additive used primarily in the production of rigid polyurethane foams, which are commonly employed in insulation applications such as refrigerators, panels, and building materials.
Addovate 390 belongs to the category of polyether-modified polysiloxanes, meaning it is a silicone-based compound that has been chemically modified to improve its compatibility and performance in polyurethane formulations.
One of the standout features of Addovate 390 is its role as a silicone surfactant or stabilizer, where it helps control the formation and structure of the foam cells.
In practical terms, it ensures that the foam develops evenly and consistently, which is critical for achieving good thermal insulation and mechanical stability in the final product.
This stabilizer is designed to be non-hydrolyzable, meaning it resists breaking down in the presence of water — a significant advantage in foam systems that involve water-based or humid environments.
Its medium to high activity gives it the versatility to work well in both slow-reacting and fast-reacting polyurethane systems, which makes it suitable for a wide range of industrial processing conditions.
The oxide of aluminum is Al2O3.
The natural crystalline mineral is called corundum, but the synthetic crystals used for abrasives are designated usually as aluminum oxide or marketed under trade names.
For other uses and as a powder, it is generally called alumina. It is widely distributed in nature in combination with silica and other minerals and is an important constituent of the clays for making porcelain, bricks, pottery, and refractories.
Addovate 390 is a polyether polyol. Acts as an emulsifier for water, catalyst and the polyester polyol.
Improves the open-cell structure of foams. Used in the low odor polyester flexible slabstock foam for textile application.
Addovate 390 can be used as main catalyst for the production of flexible ester foam based mainly on TDI 65/35.
Addovate 390 is used at 1.0 - 1.6 pphp, depending on the water content of the formulation (2.0 - 5.0 pphp).
Addovate 390 is insoluble in water, it can be emulsified in a mixture of water, Addovate 390 and Addovate SM.
Addovate 390 helps to emulsify water, paraffin oil, and water-insoluble catalysts within polyester polyols.
Addovate 390 is important to store Addovate 390 in a cool, dry place away from direct sunlight and sources of ignition.
When handling Addovate 390, appropriate PPE such as gloves, goggles, and protective clothing should be worn to prevent skin and eye contact.
Disposal of Addovate 390 should be conducted in accordance with local, regional, and national regulations.
The MSDS provides guidelines on the safe disposal of the product and any contaminated materials.
Addovate 390 is compatible with polyester polyols, enhancing their processing characteristics.
Addovate 390 is often used in combination with other additives such as Addovate SM and Addovate LM to achieve specific performance characteristics and prevent issues like core discoloration.
Accurate measurement and mixing are crucial for optimal performance.
The recommended dosages should be adhered to, and any adjustments should be made based on specific formulation requirements and performance outcomes.
Addovate 390 is valued for its excellent emulsifying properties, allowing it to effectively blend and stabilize components that are otherwise incompatible, such as polyols (the main reactive component in foams) and blowing agents like pentane, which create the foam's cellular structure.
This is important because poor emulsification can lead to defects such as collapsed cells or irregular foam density.
Uses:
Addovate 390 is the most widely used oxide, chiefly because it is plentiful, relatively low in cost, and equal to or better than most oxides in mechanical properties.
Density can be varied over a wide range, as can purity-down to about 90% alumina-to meet specific application requirements.
Alumina ceramics are the hardest, strongest, and stiffest of the oxides.
They are also outstanding and with electrical resistivity and dielectric strength, are resistant to a wide variety of chemicals, and are unaffected by air, water vapor, and sulfurous atmospheres.
However, with a melting point of only 2039°C, they are relatively low in refractoriness and at 1371°C retain only about 10% of room-temperature strength.
In addition to its wide use as electrical insulators and its chemical and aerospace applications, the high hardness and close dimensional tolerance capability of alumina make this ceramic suitable for such abrasion-resistant parts as textile guides, pump plungers, chute linings, discharge orifices, dies, and bearings.
One of the most common uses of Addovate 390 is in the insulation foam used inside refrigerators and freezers.
These appliances require a highly efficient thermal barrier to maintain cold temperatures while minimizing energy consumption.
Addovate 390 helps to produce uniform, closed-cell foam that offers excellent insulation performance.
Addovate 390s stabilizing action ensures that the foam structure is consistent and free from defects like voids or irregularities, which can compromise insulation quality.
Addovate 390 is also used in the production of rigid polyurethane foam panels for building insulation. These panels are commonly used in walls, roofs, and floors to enhance energy efficiency in homes and commercial buildings.
In this context, the additive enables stable foam formation during both continuous and discontinuous panel production, ensuring dimensional stability, proper adhesion to surfaces, and excellent long-term thermal resistance.
In industrial settings, particularly in the oil, gas, and chemical industries, polyurethane foam is often used to insulate pipes, tanks, and vessels to maintain process temperatures and prevent energy loss.
Addovate 390 plays a key role in such systems by helping to form durable, evenly distributed foam that adheres well to metal or other pipe materials, even under challenging conditions.
This contributes to both safety and energy savings in industrial operations.
Another use of Addovate 390 is in cavity filling applications, where polyurethane foam is injected into hollow spaces within walls, doors, or other structural components.
This method is used for thermal and acoustic insulation as well as to reinforce structures.
The foam must expand and cure evenly within confined spaces, and Addovate 390 ensures the foam fills the cavity without collapsing or separating, which could lead to weak spots or reduced effectiveness.
Modern polyurethane systems often rely on physical blowing agents like pentane to create the foam’s cellular structure.
However, these blowing agents are often poorly miscible with polyols.
Addovate 390 acts as a compatibilizer, helping these components blend and stabilize properly.
This is especially important in formulations aiming to be more environmentally friendly, where hydrofluorocarbons (HFCs) are being phased out in favor of low-GWP (Global Warming Potential) alternatives like hydrocarbons.

Addovate 390 may cause irritation to the eyes and skin.
It is recommended to wear appropriate personal protective equipment, such as gloves and safety goggles, to minimize exposure.
Inhalation of vapors or mists can lead to respiratory tract irritation.
Utilizing adequate ventilation and, if necessary, respiratory protection can help mitigate this risk.

Proper thermal management and adherence to recommended processing temperatures are essential to prevent decomposition.
Although Addovate 390 has a flash point exceeding 100 °C, indicating a relatively low flammability risk, it is still advisable to keep the product away from open flames and high-temperature sources.
